Aging in place & universal design
NK Construction & Design brings remodeling and structural construction together for Bucks County households. Founder Nebojsa "Nebo" Keresevic leads aging-in-place planning as a Certified Aging-in-Place Specialist (CAPS). Start with what you want the home to do better: a bathroom you can reach, room for a parent, an easier entrance or a connected level for daily living.
A Bucks County plan starts with the route between the entrance, kitchen, sleeping space and full bathroom. A one-story slab home, a split-level, a two-story colonial and an older stone farmhouse present different questions about levels, services, space and existing construction. We consider those questions with your household's routines and the remodeling scope.
The starting point can be a young family, a parent moving in, someone preparing for recovery or an owner planning to stay for decades. Bring recommendations from your occupational or physical therapist when clinical input is needed. NK coordinates the design, professional input, connected construction and applicable approvals within the agreed project scope.
Census QuickFacts reports that 23.1% of Bucks County residents are 65 or older, using July 1, 2025 Population Estimates (V2025). Planning for changing needs can also help households with young children, a parent moving in or someone preparing for recovery.

Connect the entrance, kitchen, sleeping space and full bathroom before deciding which room to change.
Discuss slabs, framing, services and level changes together with the layout, finishes and access you want.
Compare immediate comfort, longer-term adaptations and feasible phases. Start with a conversation about the project and its likely scope.
Choose the situation closest to yours. A difficult daily routine is a useful starting point for a plan that connects the 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.
Discuss bath time with young children, cleaning, carrying groceries and the route used by a visiting grandparent alongside longer-term access needs. Surface choices and the room arrangement should suit the household's ordinary routines as well as the proposed support features.
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 Lower, Central and Upper Bucks, along with Philadelphia, Montgomery, 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.
Planning during an existing remodel lets you consider support backing, future room use and connected work before finishes are closed. The right sequence follows the house and agreed scope. Days of site work after approvals should not be confused with the overall time for investigation, drawings, review and materials. NK provides a written project schedule before work starts, based on the agreed scope.
Homeowners may consider savings, home-equity borrowing or NK's Project Financing resources. Assistance depends on current program rules, funding and household eligibility. As checked November 3, 2026, the Bucks County Home Repair Program states that it has accepted no new applications since October 21, 2025; its official page links to alternative repair resources. The county Area Agency on Aging can remain a starting contact for older residents' services.
VA housing-adaptation grants may assist veterans or service members with qualifying service-connected disabilities. Some medically necessary home changes may be relevant to medical-expense deductions under IRS Publication 502; a tax professional should assess the household's facts and applicable rules. A resource link is not a funding or tax-eligibility decision.
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.
A slab-floor ranch, a split-level, a later colonial and an older stone home can raise very different questions. The existing rooms, floor construction and changes in level determine where to start. The actual house may have been altered, and its layout and construction need individual review.


Levittown, Fairless Hills, Bristol Township, Falls Township and Middletown Township
Levittown's original development was completed in 1958 with 17,311 dwellings. Its historical slab construction and radiant heating make the existing floor an important planning question. In a slab-floor bathroom, review drainage, floor levels and any original or replacement heating and other embedded services before deciding whether a level shower entry is practical. A one-story layout may reduce stair use, but doorways, bathroom space and the complete route still need assessment.
Bensalem, Feasterville-Trevose, Warminster, Southampton and Langhorne
In a split-level or bi-level home, half-flights can separate the entrance, kitchen, bedrooms and family room. First map the levels used for daily life. Converting a lower family room or garage does not by itself put sleeping and bathing on the kitchen level. Compare a suitable room arrangement on one level, a feasible addition, or a stair and specialist-equipment plan, while considering privacy, services and access between the rooms. Where stairs remain, review railings, lighting and visible level changes.
Doylestown Township, Warrington, Newtown Township, Upper Makefield, Buckingham and Lower Makefield
If the main bedroom and full bathroom are upstairs, explore whether a den, dining room or other first-floor space could support sleeping and bathing together. Review privacy, escape requirements, plumbing, existing structure and the route to the kitchen and entrance. A step down into a family room, a proposed addition or space reserved for a future elevator needs its own feasibility review; a room's label does not establish suitability.
Solebury, New Hope, Tinicum, Plumstead, Yardley and Doylestown Borough
Narrow or winding stairs, thick existing walls, sloping floors, stepped thresholds and limited headroom can shape an older home's plan. Review the existing construction before selecting opening changes, floor work or an addition. Structural design and the property's historic character belong in the same discussion; no beam material, leveling method or new opening is chosen from the house type alone.
Housing type is the start of the conversation. What matters next is whether the available room, route and building conditions support the way you want to live. A suitable plan may combine a bathroom change with laundry, room reuse or another way between floors.
A bedroom on the main floor is useful only when bathing and daily activities can be reached comfortably. Explore the compact bathroom, hallway and doorway together; borrowing suitable closet or hall space may be considered. Moving laundry from the basement is another option to review with the appliance services and available room.
A den, dining room or sunroom may be a starting point for sleeping space. Review the nearby bathroom, privacy, openings, thresholds, existing walls and route from the entrance. An addition and specialist lift or elevator are alternatives to assess where room reuse does not meet the household's needs. Compare feasible alternatives and their project-specific budgets together.
A tight bathroom or entrance may involve common elements as well as the room itself. Review management or association rules, required insurance, work access, shared systems and any exterior-approval process. These requirements belong in the construction sequence alongside the proposed layout.
Walk the route used with groceries, a stroller, a walker or a laundry basket. Connect the entrance, everyday rooms and sleeping arrangement before choosing a single improvement. A more usable room still needs a practical way to reach it.


Review the driveway, garage or walk, changes of grade, steps, landings, thresholds, railings and drainage. A graded path, ramp or side or rear entrance may be explored where the site allows. A specialist assesses any lift, equipment space and remaining circulation; property boundaries and required review help determine the options.
Consider a full bathroom and suitable sleeping space with a useful route to the kitchen and living areas. A powder room, dining room, den, rear kitchen or porch may be considered. Check privacy, helper space, services, structure and the proposed use rather than assuming any spare room can become a bedroom.
Map every change of level in a split-level or bi-level, including the route from the entrance. Review treads, rails, landings, lighting and visible transitions where stairs remain. A lift specialist considers equipment suitability, transfers and circulation; converting a lower room alone does not remove the half-flight to the kitchen.
If sleeping remains upstairs, consider the bathroom on that level, shower access, fixture layout, supports and lighting from bed to toilet. Compare those needs with the stair or equipment plan. A first-floor suite is another option to assess, rather than a decision made from floor area alone.
Review laundry carrying routes, mechanical equipment, new service routes, existing moisture and flood exposure. A proposed basement bedroom or bathroom needs review of the use, emergency escape and applicable requirements. Moving laundry upstairs may reduce stair trips; access to essential rooms during construction belongs in the plan too.
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.
Bucks County has 54 municipalities. NK confirms the applicable building-code authority and the current requirements for the actual property and proposed work. Building and trade submissions, drawings, professional input and inspections are coordinated as required by the agreed scope; the process is not assumed identical across 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.

A bathroom, bedroom or entrance change needs to fit the property as well as the household. Review the applicable building authority, sewage arrangement, flood information, historic controls and site requirements early, so they inform the options and project sequence.
Bucks County has 54 municipalities. NK confirms the applicable building-code authority and the current requirements for the actual property and proposed work. Building and trade submissions, drawings, professional input and inspections are coordinated as required by the agreed scope; the process is not assumed identical across the county.
For a home served by on-lot sewage disposal, review the existing system information and proposed room and plumbing changes early. Bucks County's Health Department administers its on-site sewage program. For example, Upper Makefield's addition and renovation instructions require county approval of the existing septic system when adding a bedroom. A new bathroom is not automatically the same question as an added bedroom; the actual proposal and applicable review determine what is needed.
Bucks County sewage programFor river-corridor properties, including those in and around Yardley, New Hope, Lower and Upper Makefield, Tinicum, Morrisville and Bristol, review the actual address and flood information before choosing an addition, entrance or basement use. 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 applicable exceptions. This is an early design constraint, not a conclusion about your property's approval or required work.
A home's designation and proposed exterior work can affect the review path. In Doylestown Borough's designated historic district, exterior features visible from a public street or way fall within its HARB and Council review process. Other municipalities have their own requirements. Compare a graded approach, ramp, side or rear route, or specialist lift with the building's character, available space and required review.
Doylestown Borough historic reviewAn addition or changed entrance must be considered with the site's property boundaries, setbacks, coverage, drainage and other applicable zoning requirements. Shared-wall or adjacent-property effects need review where the proposed work involves them. NK explores feasible design alternatives within the agreed scope; no variance or permit approval is promised.
Review any HOA or community exterior-approval process where it applies. NK coordinates project documents, drawings and material information within the agreed scope. An association's decision is a project requirement to confirm, alongside applicable municipal review.
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; these company credentials do not establish engineering authority. A lift or elevator specialist assesses equipment suitability, installation requirements, landings and circulation. NK coordinates connected remodeling and structural preparation; applicable equipment and building approvals are confirmed for the actual device and property.

Questions, answered
Explore planning questions about the existing home, changing routines and the work involved.
Some homeowners may qualify for assistance, depending on current program rules, funding and household eligibility. As checked November 3, 2026, the Bucks County Home Repair Program was closed to new applications and states that it has accepted none since October 21, 2025. Its official page links to alternative repair resources. The county Area Agency on Aging can remain a starting contact for older residents' services; a referral does not establish that another program is open or that your work qualifies.
VA housing-adaptation grants may assist veterans or service members with qualifying service-connected disabilities. Some medically necessary home changes may be relevant to medical-expense deductions under IRS Publication 502; a tax professional should assess the household's facts and applicable rules. Confirm assistance before including it in the project budget. NK's Project Financing resources are separate from public assistance and tax treatment.
A den, study, dining room or suitable addition can be explored, but a spare room needs to work as part of a complete living arrangement. Review the route to a full bathroom, cooking space and a usable entrance, along with privacy, heating, escape requirements, existing construction and any changes in floor level.
In a split-level home, converting a lower room does not by itself put sleeping and bathing on the kitchen level. For a home on septic, the proposed sleeping use also belongs in the sewage-review discussion. NK evaluates the actual room and connected route before recommending a conversion, an addition or another arrangement.
Do not assume a bathroom remains usable throughout a remodel. Discuss toilet, bathing and handwashing needs before agreeing to the construction sequence. Demolition, plumbing, waterproofing and other work can require periods when part or all of the room is unavailable. The actual scope determines those intervals.
Where the house and scope allow, building another bathroom before taking the existing one out of service may be considered. Otherwise, agree a practical temporary arrangement, nearby facilities or time away with NK before work begins, taking the household's needs into account. Temporary fixtures or uninterrupted access are not automatic inclusions; confirm responsibilities, timing and costs in the agreed plan.
