FAQ
What licenses, certifications, and professional experience does NK Construction & Design have?
NK Construction & Design combines remodeling and structural construction experience, Pennsylvania HIC registration, a Philadelphia contractor license and an owner with the NAHB CAPS designation.
Remodeling experience with a structural foundation
Owner and founder Nebojsa (Nebo) Keresevic brings more than 20 years of construction and remodeling experience, including residential and commercial work. NK specializes in structural construction and structural remodeling alongside finished kitchen, bathroom and whole-home renovations.
That background connects the room you want with the work behind it: load-bearing wall removal, beam and lintel installation, floor leveling, structural framing and the finishes that complete the space. Kitchen work includes full remodels, open-concept layouts, expansions into adjoining dining and family rooms, and aging-in-place kitchens. NK coordinates design, structural modifications, permits, construction and finishing within one project. A dedicated licensed structural engineering partner handles beam, post and footing design, stamped drawings, permit submissions and special inspections as required by the agreed scope.
NK's corporate office is at 1324 Locust St, Philadelphia, PA 19107, in Center City, with a design studio at 4900 S Broad St, Philadelphia, PA 19112. The team serves Philadelphia and Bucks, Montgomery, Delaware and Chester counties.
Pennsylvania registration and Philadelphia licensing
NK holds Pennsylvania Home Improvement Contractor Registration #176617 through the Pennsylvania Office of Attorney General. This is the state registration for home-improvement contracting; it is distinct from a professional license and is not an endorsement of a contractor's skill.
NK also holds Philadelphia Contractor License #059408 through the city's Department of Licenses and Inspections. It applies to contracting work in Philadelphia and is separate from Pennsylvania HIC registration. When comparing contractors, ask for the city license number rather than relying on advertising that says they serve Philadelphia. Outside the city, the team confirms the contractor, trade and permit requirements applicable to the property and scope during planning.
NK is insured. Insurance documentation and the contractor, trade and design-professional credentials appropriate to your project can be discussed before work begins. Contractor registration and licensing do not confer professional engineering licensure.
Nebo Keresevic's Certified Aging-in-Place Specialist designation
Nebo holds the Certified Aging-in-Place Specialist (CAPS) designation awarded through the National Association of Home Builders (NAHB). The program focuses on home modifications for aging in place, supporting thoughtful choices about access, circulation and everyday use in kitchens, bathrooms and the wider home.
CAPS is Nebo's individual professional designation. It does not itself confer structural engineering licensure; engineering remains the role of the appropriately licensed professional.
Industry memberships
NK is a member of the National Association of Home Builders (NAHB), the national home-building industry association, and the Building Industry Association of Philadelphia, a local association focused on residential development and construction. These memberships connect the company with its industry; they are separate from contractor registration, licensing and individual designations.
Customer reviews and independent profiles
Past review snapshots have shown a 4.9-star Google rating from more than 60 Google reviews, a BBB A+ rating and BuildZoom Top 1% recognition.
