Connect the everyday rooms
Consider the full entrance-to-bathroom route, rather than improving one room in isolation.
Aging in place & universal design
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 Montgomery County home you know.

Aging in place & universal design
NK Construction & Design connects remodeling and structural construction for Montgomery County households. Founder Nebojsa "Nebo" Keresevic leads aging-in-place planning as a Certified Aging-in-Place Specialist (CAPS). Begin with the rooms and routines that need to work better, whether you are making space for a parent, preparing for recovery or planning to stay for decades.
The first question is how the entrance, kitchen, sleeping space and full bathroom connect. An older stone home in Lower Merion or Elkins Park presents different planning questions from a Norristown twin, a postwar split-level or a later colonial. We review levels, circulation, existing construction and services together before recommending a room change or a larger project.
A useful plan considers everyone who lives in or visits the home: a child in a stroller, an adult on crutches, a visiting grandparent or someone who needs seated work space. Bring recommendations from your occupational or physical therapist when clinical input is needed. NK coordinates the remodeling, professional input and applicable approvals within the agreed project scope.
Census QuickFacts reports that 21.2% of Montgomery County residents are 65 or older, using July 1, 2025 Population Estimates (V2025). Planning for changing needs can also help younger households think through everyday access, recovery and shared living.

Consider the full entrance-to-bathroom route, rather than improving one room in isolation.
Review existing walls, floors, services and level changes alongside your priorities.
Discuss what matters now, what can follow and which provisions make sense during an existing remodel.
The difficult routine is often more useful than a product name. Choose the situation closest to yours and explore the connected rooms, route and building work.
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.
Include bath time with children, cleaning, groceries and carrying a laundry basket in the conversation. Consider what the same room needs to do for a parent, guest or someone recovering from treatment; individual clinical recommendations remain the care team's role.
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 Montgomery County, from the Main Line and eastern suburbs to the North Penn area, Perkiomen Valley and Upper Montgomery County, as well as Philadelphia, Bucks, Delaware and Chester counties.
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 the 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.
During a planned remodel, review support backing, future room use and connected work before finishes are closed. The cost and sequence depend on the actual house and agreed scope. A few days of site construction after approvals is a different interval from the overall investigation, drawings, review and procurement process. NK provides a written project schedule before work starts, based on the agreed scope.
As checked November 4, 2026, Montgomery County's Home Repairs Program is not accepting new applications or adding households to its waitlist. The county states that its one-time Whole Home Repairs Program will not reopen because funding is no longer available. Its official page links to alternative repair resources; those referrals do not establish that another program is open or that your work qualifies.
Montgomery County's aging services can be a starting point for older residents' support. Homeowners may also consider savings, home-equity borrowing or NK's Project Financing resources. VA housing-adaptation grants may assist people with qualifying service-connected disabilities; some medically necessary changes may be relevant to medical-expense deductions under IRS Publication 502. Confirm assistance before budgeting for it, and have a tax professional assess your household's facts. Financing is separate from public assistance and tax treatment.
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.
Montgomery County homes include older stone properties, borough twins, postwar layouts and later suburban homes. Their useful planning differences are levels, room connections, structure, services and site conditions; a house-type label does not establish what work is feasible.


Lower Merion, Narberth, Bryn Mawr, Cheltenham, Elkins Park, Jenkintown and Abington
An upstairs bedroom and full bath, raised first floor, plaster over older framing or narrow hall can complicate the daily route. Explore a library or sunroom conversion, stacked closets or a secondary stair for specialist equipment, and a compatible entrance. Confirm the actual structure, circulation and any designation-dependent review.
Norristown, Conshohocken, Bridgeport, Pottstown, Lansdale, Ambler and Royersford
A narrow footprint, upstairs-only bathroom, steep stair or sidewalk steps may call for connected changes. A powder room, rear bedroom or side or rear approach can be explored with plumbing, usable sleeping space and property boundaries. Shared-wall effects and actual equipment fit need their own review.
Willow Grove, Hatboro, Horsham, Glenside, Plymouth Meeting and King of Prussia
Review the small bathroom, tub, hall and basement laundry together. A ranch may offer main-floor sleeping, but the full route still matters. In a Cape or split-level, trace every half-flight; converting a room on another level does not create kitchen-level sleeping and bathing. Room reuse or a suitable addition can be compared.
Blue Bell, Lower Gwynedd, Upper Dublin, Maple Glen, Collegeville and Huntingdon Valley
An upstairs primary suite, sunken family room or turning stair can affect the plan. Explore study-to-bedroom reuse with a full bathroom, changes in floor level, a suitable addition or future equipment space. Existing structure and services determine the work; association requirements may apply to common or exterior elements.
Different housing types can share a need for easier daily living without sharing the same solution. Compare room reuse, additions and specialist equipment in the context of the complete home.
Review a nearby full bathroom, doorway, hall and usable entrance with the sleeping space. Borrowing suitable closet or hall space and moving laundry upstairs may be options, subject to the actual room and services.
A study, dining room, library or sunroom may be considered for sleeping. Review privacy, heating, emergency escape, bathroom access, thresholds, walls and plumbing before choosing a conversion. Compare an addition or specialist lift where room reuse does not meet the household's needs.
Common elements, shared systems and exterior work can involve management or association requirements. Review work access, required insurance and any approval process alongside the construction scope; do not assume every change falls entirely within the unit.
Follow the way the household enters, cooks, rests and bathes. Consider groceries, a stroller, a walker or a laundry basket along the same route before choosing a single fixture or room improvement.


Review steps, grade changes, landings, thresholds, railings and drainage from the driveway, garage or sidewalk. Compare a graded walk, side or rear route, ramp or specialist equipment where the property and required review allow.
Connect a suitable sleeping room and full bath with the kitchen and living space. A powder room alone may not provide the bathing arrangement needed. Review privacy, helper space, structure, services, proposed use and any on-lot sewage implications.
Trace the half-flights between entry, kitchen and bedrooms. Consider railings, lighting and visible level transitions where stairs remain. A lift specialist assesses equipment suitability, transfers, landings and circulation; no house label guarantees a fit.
Where sleeping stays upstairs, consider the bathroom on that level, lighting from bed to toilet, supports and the stair or equipment plan. A first-floor suite is an alternative to assess, not a conclusion based on available floor area alone.
A basement suite still requires a practical route and review of the proposed sleeping use, emergency escape, moisture, flood information and applicable approvals. Main-floor living and an addition can be compared; neither a caregiver room nor any basement use is automatically suitable. Moving laundry upstairs may reduce carrying on stairs.
Planning a return home
If someone is returning from Abington, Lankenau or Bryn Mawr Hospital, or another care setting, bring the discharge team's recommendations, the anticipated date and the rooms the person will use into the conversation. NK confirms the project's suitability, scope and actual availability; work before a discharge date is not guaranteed.
Follow the care team's guidance on the person's clinical needs. Construction planning can separate immediate priorities from larger decisions so that the long-term arrangement receives the attention it needs.

Review the route from the car, bathroom access, support locations, toilet arrangement, secure stair railings and lighting from bed to bath against the care team's recommendations. The actual user, building conditions and agreed work determine what can be addressed.
Compare a curbless shower, first-floor sleeping and full bathing, wider openings, a permanent easier entrance or specialist lift/elevator planning. Larger design, investigation, approvals and construction may follow a different schedule from focused work.
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.
Montgomery County has 62 municipalities. NK confirms the applicable building-code authority and current requirements for the property and actual work. Submissions, drawings, qualified professional input, trade permits and inspections are coordinated as required by the agreed scope; the process is not assumed identical throughout the county.
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.

Local requirements belong in the early planning discussion alongside the room layout. Review the actual municipality, sewage arrangement, historic designation, flood information and site constraints before choosing an addition, entrance or new living space.
The county's 62 municipalities do not establish one countywide building-permit process. Lower Merion, Abington, Cheltenham, Upper Dublin and Norristown are examples of places where the applicable authority and submission path must be confirmed. NK coordinates the actual required documents, professional input and inspections within the agreed scope.
In Lower Merion, designation and the proposed work inform the historic-review path. Its listed local districts include Ardmore Commercial Center, Gladwyne, Haverford Station and Mill Creek. Review an entrance, ramp, railing, addition or equipment proposal with the appropriate township process rather than assuming an old-looking home is designated or every interior or hidden change is exempt. Other Montgomery municipalities have their own requirements.
Lower Merion historic reviewThe Schuylkill corridor and areas around the Wissahickon, Pennypack, Perkiomen and Skippack creeks warrant address-specific flood review. The 2021 Hurricane Ida experience in Norristown and Bridgeport is historical context, not a flood-zone determination for your home. Review actual mapped status, water history, equipment locations and the proposed use before choosing an entrance, addition or basement arrangement. The federal substantial-improvement definition uses work costing 50% or more of the structure's pre-improvement market value, excluding land; local officials determine applicability, including stricter or cumulative provisions and exceptions.
For a property on septic, review existing system records and the proposed room, plumbing and wastewater-flow changes early. Montgomery County's Office of Public Health administers its on-lot program; its re-use/change-of-structure process considers the effect on the existing system. Confirm the actual sewage arrangement for a home in Upper Hanover, Marlborough, Salford, Franconia, Douglass or another municipality rather than assuming it from the town name. A new bathroom is not automatically an added-bedroom or system-expansion trigger.
Montgomery County on-lot sewage programIn Narberth, Jenkintown, Ambler, Hatboro, Lansdale and other communities, review actual setbacks, coverage, drainage and property boundaries before selecting an addition or changed entrance. Compare feasible alternatives where the initial idea conflicts with a requirement; no variance or approval is promised.
Shared-wall and adjacent-property effects need review where the work involves them. Carriage-home, condominium and 55+ community projects may also require association review of common or exterior elements, drawings, material information, insurance and work access. Those requirements inform the agreed construction sequence.
NK holds Pennsylvania Home Improvement Contractor Registration #176617. Its Philadelphia Contractor License #059408 is a Philadelphia credential, distinct from Pennsylvania registration. NK carries insurance. Engineering and regulated-trade work require the appropriately qualified professionals for the agreed scope; company credentials do not establish engineering authority. A lift or elevator specialist assesses equipment suitability and installation requirements; NK coordinates the connected remodeling and structural preparation, with applicable approvals confirmed for the actual device and property.

Questions, answered
Explore the planning questions that connect the existing home, changing routines and the proposed work.
Yes. NK Construction & Design can work on party-wall conditions in Philadelphia rowhomes and other attached properties. Depending on the project, this may involve structural repairs, stabilization, reinforcement, masonry work, framing, beam or support installation, or work associated with remodeling and structural alterations.
Party-wall work needs to be evaluated in the context of the existing building and the neighboring structure because the wall may serve structural, fire-separation, weather-protection, or other functions. NK reviews the conditions and project scope before determining the appropriate repair or construction approach.
Where permits, engineering, inspections, or coordination with adjoining-property conditions are required, those requirements are addressed as part of project planning.
For a basement remodel in a rowhome or twin, NK checks shared party walls for loose mortar, cracks and moisture and plans appropriate repointing and moisture treatment where needed. Structural changes or underpinning along the shared wall require engineering and careful sequencing that accounts for the neighboring foundation. The assessment determines how neighboring property is protected; it is not a promise of no impact.
Bring the discharge or therapy team's recommendations, the anticipated return date and the rooms the person will use into the conversation with NK. NK prioritizes these inquiries while confirming whether it can take on the work, the actual scope and availability. Clinical guidance remains the care team's role; a discharge date does not guarantee construction can be completed beforehand.
Separate immediate priorities from longer-term remodeling decisions. Discuss entrance and bathroom access, support locations, the toilet arrangement, secure rails, clear routes and lighting against the person's recommendations and existing conditions. A curbless shower, first-floor bedroom and full bath, wider openings or specialist equipment may require a larger design, approval and construction process. Agree what can realistically be addressed now and what needs a separate phase.
For a Montgomery County property near the Schuylkill River or the Wissahickon, Pennypack, Perkiomen or Skippack creeks, review actual flood information and water history before choosing an addition, entrance, basement use or equipment location. Norristown, Bridgeport, Conshohocken, Upper Merion, Royersford and Pottstown are planning examples along the river corridor, not a finding that every property there is mapped in a flood zone. The 2021 Ida flooding is historical context rather than your home's current designation.
The federal substantial-improvement definition uses work costing 50% or more of the structure's pre-improvement market value, excluding land. Local officials determine applicability under the local ordinance, including any stricter or cumulative provisions and exceptions. NK includes the actual property and proposed work in early planning; this does not determine your home's approval, elevation requirements or suitable living space.
