A home that works at every age.
Plan around the household you have and the changes ahead. Consider bathrooms, sleeping space, entrances and stairs together, whether you are welcoming a parent, preparing for recovery or staying in the Chester County home you know.

Aging in place & universal design
NK Construction & Design brings remodeling and structural construction together for Chester County households. Founder Nebojsa "Nebo" Keresevic leads aging-in-place planning as a Certified Aging-in-Place Specialist (CAPS). Begin with the routines that are becoming difficult, the people who use the home and the changes you want to prepare for.
A fieldstone farmhouse assembled through several additions raises different questions from a West Chester twin, a postwar split-level or a later colonial. Review floor heights, entrances, sleeping and full bathing, kitchen use and the existing construction together. A new first-floor bath, a recessed shower floor, a wider opening or a connector can be explored with the qualified design and approval work the actual scope needs.
The plan may begin with a stroller, a parent joining the household, crutches during recovery or a decision to stay for decades. Bring recommendations from your occupational or physical therapist when clinical input is needed. NK connects household priorities with the remodeling scope, written alternatives, early cost guidance and possible phases; individual clinical and engineering roles remain distinct.
Census QuickFacts reports that 19.8% of Chester County residents are 65 or older, using July 1, 2025 Population Estimates (V2025). Planning more usable rooms and routes can also help younger households consider daily comfort and changing needs.

6 homeowner situations.

The features considered in aging-in-place remodeling can be useful at different stages of life. A level shower entry, a usable doorway or main-floor sleeping space may help a household today as well as support future plans. The right combination starts with your household's routines and the spaces you use most.
For a parent joining the household, a first-floor suite with its own bathroom can be explored alongside mixed-height work areas and routes between the kitchen, living room and bedroom. For families, an entrance used with a stroller, groceries or a laundry basket is a useful place to start the conversation.
A common starting point

Bathroom accessibility is a common starting point for aging-in-place improvements. Easier shower access, comfortable circulation and well-placed supports can address everyday priorities while helping you consider the routes and rooms around the bathroom.
A tub or shower replacement in a layout that already works is a different scope from moving a bathroom downstairs, changing the shower floor or widening an opening. Look beyond the package name to see which layout changes, construction and approvals are included.
Compare what the contract actually provides. If someone will use a walker, wheelchair or shower seat, consider the whole route and room layout before selecting a shower product. NK can discuss whether a focused change or a more connected remodel addresses the priorities.

| Planning question | Focused replacement | Connected remodeling |
|---|---|---|
| Purpose | Update the tub or shower within a layout that fits the user. | Review where the bathroom is and how the household reaches and uses it. |
| Shower entry | Check the proposed base, threshold and relationship to the existing floor. | Explore a low-threshold or curbless arrangement where framing, waterproofing and drainage allow. |
| Location | Confirm whether the contract retains the existing bathroom location. | Assess whether a new first-floor bathroom is practical in the available space. |
| Doors and walls | Check whether any doorway or wall work is included. | Coordinate opening changes with structure and services where required. |
| Materials | Understand the offered product system, finish choices and maintenance needs. | Choose tile, stone, panels or other appropriate finishes as part of the full room design. |
| Supports | Confirm support-bar locations and the underlying wall construction. | Plan suitable backing and support positions with the wall assembly and user needs. |
| Permits and design | Determine requirements from the actual work, including connected trade work. | Coordinate drawings, professional input and permits that apply to the alterations. |
| Schedule | About a day on site is a planning example for a suitable focused installation; confirm preparation and the actual contract. | Days for a shower conversion; weeks to months for structural work are planning examples, not completion promises. Design, approvals, investigation, materials and connected construction determine the schedule. |
Explore design concepts for everyday tasks, from reaching a kitchen cabinet to moving between floors. The layout, finishes and support features can be tailored to your home; lift and elevator options also need an equipment specialist's assessment.

NK Construction & Design has its main office at 1324 Locust St, Unit 527, Philadelphia, PA 19107, and design studio at 4900 S Broad St, Philadelphia, PA 19112. We serve Chester County, from the Main Line and Great Valley to West Chester, Phoenixville, the Brandywine Valley and northern, western and southern communities, as well as Philadelphia, Bucks, Montgomery and Delaware counties. Coverage does not imply a Chester County office or a documented local project.
Founder and owner Nebojsa "Nebo" Keresevic brings more than 20 years in construction, including beam installation, load-bearing wall removal, sagging floors, bowing foundation walls and staircase relocation. He leads NK's aging-in-place planning as a Certified Aging-in-Place Specialist (CAPS), connecting the household's priorities with remodeling and structural work.
CAPS is a designation from the National Association of Home Builders (NAHB), covering communication with homeowners, livable-home design and practical construction solutions. The programme includes an ethics pledge and ongoing education. That background helps connect the household's changing needs with remodeling choices, while engineering, specialist equipment and clinical advice remain distinct professional roles.
NK remains your project point of contact for the design and construction scope. The company is a BIA member, rated A+ by BBB and ranked in BuildZoom's Top 1%. Explore NK's projects and client reviews, then discuss the rooms, routes and priorities in your home.
Costs follow the scope of work. The examples below are planning ranges, not fixed quotations or guaranteed completion periods. A support or lighting upgrade, a complete accessible bathroom and a first-floor suite involve different construction and planning. Planning related changes together helps you understand the full investment and choose priorities before construction starts.
Start with a conversation about your plans, the suitability of the project and its likely scope. Following that conversation, NK may choose to provide an estimate without charge, at its discretion. The estimate should account for the work and supporting design, coordination and approvals needed for the agreed scope. Existing conditions, structural changes, trade work, finish selections, material availability and access during construction affect the budget and sequence. Specialist work and applicable design or engineering are included or coordinated according to the agreed contract scope; they are not automatically excluded or separately charged. The planned Home Safety & Longevity Assessment provides written priorities and preliminary budget ranges, with scope, deliverables and any fee confirmed before the visit.
These are planning examples, not quotations or fixed commitments. A farmhouse opening, addition or equipment installation may involve different investigation and connected work from a focused bathroom change. Consider useful provisions during an existing remodel without assuming a saving for every feature. Site construction after approvals differs from the full design, review and procurement interval; NK confirms a written schedule for the agreed scope.
Chester County's original Whole Home Repairs announcement described awards below $25,000 for eligible repairs. That historical limit does not establish an available award. The county's October 22, 2026 update says the program concludes December 31, 2026 and demand exceeded capacity. It names Good Works, Habitat for Humanity of Chester County, Good Neighbors Home Repair and the Housing Partnership of Chester County as repair resources; confirm actual availability and terms before relying on assistance.
The Chester County Department of Aging Services can be a starting point for older residents' support. Savings, home-equity borrowing and NK's Project Financing resources are separate options. VA housing-adaptation grants may assist people with qualifying service-connected disabilities; some medically necessary changes may be relevant under IRS Publication 502. Confirm program eligibility and ask a tax professional about your household's facts. No award, deduction or return on investment is promised.
Discuss support locations and backing, a second rail where suitable, lighting, lever hardware and fixture changes. Access to the existing construction and the selected products influence the work. Planning example: hundreds to low thousands; usually days.
Plan the entry, shower controls and seating, door and fixture layout, waterproofing, drainage and related plumbing/electrical work together. The existing floor and services affect the scope. Planning example: thousands to low tens of thousands; usually days to weeks.
Consider usable room area, new service routes, framing and openings, exterior access and any addition. Professional design and applicable approvals are part of developing a realistic scope before a project-specific price and schedule. Planning example: usually months, including permits; priced after engineering.
An original stone core, later wing and more recent kitchen can create a home with several construction histories and floor levels. Review the actual connections before choosing how to make daily living easier; the age or farmhouse label does not establish dimensions or feasibility.

Trace the transitions between the original rooms and additions. Suitable framing changes, an appropriately designed ramp or a different room arrangement may be explored, with headroom, circulation, structure and the user's needs considered together. A continuous first-floor route is a design objective, not an automatic outcome.
Review the actual masonry, supports, load paths and earlier alterations before choosing a wider doorway. Stone thickness varies; an 18-inch wall example is not a measurement of your home. Qualified engineering determines any required lintel, beam and support design, with temporary support and masonry work professionally planned for the scope.
A winding or steep stair needs an equipment specialist's assessment of transfers, landings and remaining circulation before a stairlift is chosen. A stair rebuild and rails may be considered where feasible; compare a suitable first-floor suite, different route or elevator instead of assuming any one option fits.
A new first-floor bedroom and full bath or equipment space may be explored in a suitable connector or wing. Compare the effect on historic fabric with setbacks, easements, drainage, septic fields and the complete route from parking. Leaving the stone core intact can be a planning aim without establishing that an addition is permitted or best for every property.
Different homes can present similar daily difficulties while needing different building work. These supplied housing examples are planning context, not evidence of an NK project at a particular address.
West Chester, Phoenixville, Downingtown, Kennett Square and Malvern
Review front steps, a raised first floor, steep stair, upstairs-only bath, narrow lot and any historic designation. A rear entrance, pantry or mudroom bathroom, suitable stair alteration or specialist equipment can be compared with the actual route and approval path.
Berwyn, Paoli, Devon, Frazer, West Goshen and Westtown
Consider the tub, small bathroom, narrow doorway, sunken den and basement laundry together. A ranch may offer main-floor sleeping, but the full entrance-to-bathroom route matters. Trace every half-flight in a split-level before comparing bathroom, doorway, laundry or room changes; one usable room on another level is not a complete living arrangement.
Exton, Chester Springs, Uwchlan, West Bradford, Kennett and Landenberg
An upstairs primary suite, curved foyer stair and second-floor laundry can shape the plan. Explore a study-to-bedroom conversion, powder-room expansion to full bathing, suitable addition or specialist elevator route in an available closet stack or exterior space. Actual structure, services, transfers and approvals determine the work.
Follow the entrance, kitchen, suitable sleeping space and full bathroom as one arrangement. Include groceries, a stroller, a walker or a laundry basket when discussing how the original house and additions connect.


Review long approaches, steep grades, steps, landings, thresholds, drainage and boundaries. A graded path, side or rear entrance, ramp or specialist lift needs its own site and approval review; a bank-barn garage does not establish a step-free connection.
Compare a den, study, pantry or mudroom arrangement with sleeping privacy and a full bathroom near the kitchen. Review changes in floor height, heating, emergency escape, services, proposed room use and any sewage implications before choosing a conversion.
Trace each half-flight, winder and level transition. Consider rails, lighting and visible transitions where stairs remain; specialist equipment requires review of fit, transfers and landings. A suite or addition may provide another route where the property allows.
Where sleeping remains upstairs, review lighting, the path to the toilet and the stair or equipment arrangement. Compare the practical use of an existing suite with suitable main-floor alternatives, including the connected construction each needs.
Moving laundry to an appropriate daily living level may reduce carrying on stairs. Any basement sleeping use or equipment location still needs review of access, emergency escape, moisture, flood information and approvals. The room's label or available area does not establish suitability.
Compare the alternatives
Compare specialist equipment with changing where daily living happens. The right option depends on the household, existing construction, available route, property requirements and the full connected scope.
Relative cost is a planning comparison, not a quotation or fixed ranking: equipment selection, investigation, structural work and site conditions can change the order. NK prices the realistic agreed alternatives; specialist suitability and ongoing service need their own discussion.

Swipe to compare all five planning questions
| Option | Suitable use | Work involved | Relative cost | Cautions |
|---|---|---|---|---|
| Stairlift | A suitable stair and a person whose transfer needs can be accommodated, as assessed with the appropriate specialist and clinical input. | Specialist equipment selection and installation, with any required stair or structural preparation and connected remodeling defined separately. | Often a smaller equipment scope than larger alterations; total installed and connected work still needs pricing. | Transfers, landings, circulation, servicing and actual stair geometry matter. Farmhouse winders or a curved stair do not establish either fit or impossibility. |
| Home elevator | A household considering continued use of upstairs rooms where equipment and the connected route can be accommodated. | Device-specific enclosure, floor openings, supports, services and any pit or exterior addition requirements; no universal device arrangement is assumed. | A substantial equipment and building scope; compare a complete proposal rather than equipment price alone. | Suitable space, landings, remaining circulation, applicable approvals and ongoing service require review. A closet stack or image does not prove fit. |
| First-floor suite | A house with suitable study, den, living room, garage or addition space connected to the everyday rooms. | Appropriate sleeping space and full bathing, with room-use, privacy, heating, emergency escape, structure and services considered together. | Potentially a moderate-to-large remodeling scope; existing rooms and connected construction determine cost. | A powder room alone is not full bathing. Confirm sewage review where applicable, including Kennett's septic-served bedroom/bathroom requirement. |
| First-floor addition | A household without suitable spare rooms, or a property where a compatible new wing may reduce changes to the original stone core. | Foundation, framing, roof, services and finishes, connected to suitable sleeping, bathing, kitchen and entrance routes. | Often a larger construction scope; size, ground conditions and the full design may change the comparison. | Setbacks, lot coverage, drainage, easements, septic capacity and designation-dependent historic review can constrain the proposal. Approval is not promised. |
We start with what you want your home to do better, then work through the layout, building conditions and priorities together. The result is a remodeling scope shaped around your household and the spaces you use every day.
Call or send us a project inquiry. Discuss who lives in the home, who visits, which routines are difficult and what may change.
The comprehensive assessment includes a room-by-room walkthrough and measurements of doors, landings, thresholds and circulation, together with bathroom, stair, lighting and visible structural observations. Scope, deliverables and any applicable fee are agreed before the visit; this planned service is not yet bookable.
Following the assessment, NK prepares a written report with immediate priorities, comfort improvements, longer-term adaptations, remodeling alternatives, preliminary budget ranges and phasing opportunities, providing a basis for the agreed project scope.
NK provides and coordinates design and architectural services. We bring structural questions, equipment requirements and any recommendations from your clinician into the planning conversation, with the appropriate professional input for the work.
Chester County has 73 municipalities, not one countywide building-permit process. NK confirms the actual building-code authority, property and scope requirements, then coordinates required drawings, qualified professional input, submissions, trade work and inspections within the agreed project.
Discuss access to a toilet, shower, sleeping space and the entrance during work. Building a new bathroom before altering the existing one may be an option where the agreed design and conditions allow.
Coordinate required project inspections and review the agreed work with the household. Walk through the rooms, controls and daily routes together, and review how the finished work meets the agreed scope.
Planned to launch alongside Aging in Place Remodeling, NK's Home Safety & Longevity Assessment evaluates how your home supports everyday living and how it could adapt to changing needs. It includes a room-by-room walkthrough, measurements of doorways, thresholds, steps, hallways and circulation spaces, and review of bathrooms, stairs, lighting and visible structural conditions.
NK then prepares a written report identifying priority improvements, longer-term adaptations, remodeling alternatives, preliminary budget ranges and opportunities to phase the work. This comprehensive assessment goes beyond an ordinary project estimate to provide a sound basis for planning and budgeting.
The assessment identifies where architectural, structural engineering, lift-specialist or your own occupational or physical therapist's input may be appropriate. Scope, deliverables and any applicable fee are confirmed before the visit. Detailed engineering investigations, specialist evaluations and permit drawings are separate services where required. The assessment is not yet available to book.
Porch steps, routes from parking, thresholds, handrails, available site space and drainage.
Hallways, openings, door swings, furniture positions and changes in floor level or material.
Treads, rails, landings, lighting and any questions that need an equipment specialist.
The route to the room, shower access, toilet approach, supports and space for a helper.
Seated and standing tasks, storage, appliances and routes used while carrying items.
Space around the bed, transfers, controls and the night route to the toilet, guided by individual needs.
Entrances, stairs and night routes, including glare and shadows that make level changes harder to see.
Exit doors, obstacles and routes from sleeping and living areas, with requirements determined for the proposed use.

Bring local requirements into the plan before choosing a new room, opening, entrance or addition. The actual address, municipality, sewage arrangement, designation and site conditions determine the review.
Tredyffrin, Kennett, West Chester and the City of Coatesville illustrate why the property's actual authority and current submission path must be confirmed. Municipalities administer or arrange UCC enforcement; required plans, trade permits, professional input and inspections depend on the work. NK coordinates the agreed approval scope.
Confirm whether the home uses on-lot sewage. Kennett Township's interior alteration packet requires Chester County sewage approval when adding a bedroom or bathroom to a septic-served home. Review existing records, proposed use and sewage flows with the county evaluation process; a system modification permit is a distinct question. Do not extend one township's exact packet to every address or impose septic requirements on public-sewer homes.
Chester County sewage permittingWest Chester Borough and Phoenixville Borough have HARB processes for work within their respective review scopes. Confirm designation and proposal before selecting an entrance, ramp, porch change or addition. A compatible side or rear approach may be explored, but neither a hidden location nor an interior label guarantees exemption. NK prepares required project materials within the agreed scope; the review does not promise approval.
Phoenixville historic-review informationThe 2021 Ida flood of record at Chadds Ford is historical context, not a determination of a Chester County property's flood status. Review the actual address and water history near the Brandywine, French Creek, Valley Creek and Schuylkill before choosing basement use, equipment or an addition. The federal substantial-improvement definition uses 50% or more of the structure's pre-improvement market value, excluding land; local officials determine applicability, including stricter or cumulative provisions and exceptions. NK includes the actual requirements in planning.
Chester County floodplain resourcesReview driveway length, grades, wells, septic fields, setbacks, lot coverage, drainage and conservation easements with the proposed entrance or addition. A large lot is not automatically unconstrained. Compare practical alternatives where the first idea conflicts with a requirement; no variance or easement consent is assumed.
Carriage-home, condominium and age-restricted communities may require association review of common or exterior elements. Clarify drawings, material information, insurance, work access and review timing for the actual proposal. Interior work may still affect shared systems or elements, so neither an interior label nor a municipal permit alone establishes association consent.
NK holds Pennsylvania Home Improvement Contractor Registration #176617. Its Philadelphia Contractor License #059408 is a separate Philadelphia credential. NK carries insurance. Engineering and regulated-trade responsibilities belong to appropriately qualified professionals. The equipment specialist assesses lift or elevator suitability; NK coordinates connected remodeling and structural preparation within the agreed scope.

Questions, answered
Explore farmhouse adaptations, equipment alternatives, septic review and connected daily living.
Yes, when the property is in West Chester Borough’s Historic District and the proposed work is within HARB’s review scope. The Borough states that HARB advises on applications to demolish, renovate, and alter buildings in the Historic District and reviews supporting materials such as written documents, images, and, when relevant, floor plans. The property’s district status and proposed work should be confirmed before the remodeling path is defined.
Phoenixville has its own HARB process for proposed exterior changes in its Downtown Historic District; do not assume the two boroughs have identical procedures. For an entrance, ramp or porch proposal, NK confirms the address, designation, current review scope and required materials during planning, and coordinates the agreed submission. A side or rear location may be explored but does not automatically remove review or guarantee approval.
Chester County's original Whole Home Repairs announcement described awards below $25,000 for eligible repairs. That historical limit is not an available award promise. The county's October 22, 2026 update says the program concludes December 31, 2026 and demand exceeded capacity. It identifies Good Works, Habitat for Humanity of Chester County, Good Neighbors Home Repair and the Housing Partnership of Chester County as repair resources. Confirm actual availability, eligibility and terms before including assistance in the budget.
The Department of Aging Services can be a starting point for older residents' support. Qualifying veterans may explore VA housing-adaptation grants, and a tax professional can assess whether medically necessary changes are relevant under IRS Publication 502. NK's Project Financing resources are separate from public assistance and tax treatment; no award or deduction is guaranteed.
The cost of aging-in-place remodeling depends on the rooms and routes involved, existing conditions, layout changes, structural and trade work, finishes and applicable design and approval requirements. Start with a conversation about your project and likely scope. NK may then choose to provide an estimate without charge, at its discretion. Reviewing your home and defining the work gives you a more useful basis for budget decisions.
For early Chester County planning, focused safety work is illustrated in the hundreds to low thousands; a curbless shower or accessible bathroom in the thousands to low tens of thousands; and a first-floor suite, addition, equipment-related work or major farmhouse structural work is individually scoped and priced after appropriate design or engineering review. These are company planning examples, not quotations or fixed commitments. The actual house, professional input and agreed work determine cost.
