NS Design and Build creates custom second-story additions in Highlands Ranch for homeowners who need more space without relocating or expanding their home’s footprint. Whether you want additional bedrooms, an upstairs bathroom, a primary suite, a bonus room, or a complete second floor, our design-build team manages structural evaluation, engineering, permits, construction, and interior finishes. Call (720) 641-4365 or request a free quote to schedule a walkthrough and feasibility review.
We inspect your Highlands Ranch home, discuss your square footage needs and budget, and evaluate the existing roof, framing, foundation, and site conditions.
We coordinate structural engineering to assess load-bearing walls, floor joists, foundation capacity, height restrictions, and reinforcement requirements.
Our team creates a functional second-floor layout and provides a clear proposal covering stairs, bedrooms, bathrooms, roof modifications, finishes, costs, and the anticipated timeline.
We prepare permit documents, assist with HOA submissions, finalize material selections, schedule trades, and plan temporary protection for the existing home.
Our crews complete structural reinforcement, roof removal, framing, floor systems, roofing, plumbing, electrical work, HVAC, drywall, cabinetry, flooring, and trim.
We coordinate required inspections, complete punch-list items, review the finished addition with you, and provide applicable warranty and project documentation.
The effect on your existing living space depends on stair placement, structural reinforcement, and mechanical upgrades. Some ground-floor walls or ceilings may need to be opened to reinforce load-bearing walls, connect plumbing and electrical systems, or install new stairs. We plan these changes carefully to protect the main living area and help the new floor integrate naturally with the original home.
Yes. Many homeowners combine a second-story addition with a whole-house renovation to update the kitchen, improve the ground-floor layout, remodel a finished basement, or modernize the home’s systems and finishes. Coordinating the work as one project can create a more cohesive design and reduce the need for additional construction later.
Load-bearing walls and floor joists determine how the extra weight of the new second floor will be transferred through the home’s existing structure and foundation. Structural engineering helps identify which walls can remain, where reinforcement is needed, and how the new floor system should be framed to maintain structural integrity.
Yes. We plan insulation, ventilation, windows, air sealing, and HVAC modifications so the new living space remains comfortable throughout the year. The system may require new ductwork, upgraded equipment, or separate temperature controls to properly heat and cool the additional square footage.
A second-story addition is a major investment because it involves structural engineering, foundation evaluation, roof removal, a new roof, mechanical systems, and complete interior construction. There are many variables that affect labor costs and material selections, so we provide a clear picture of the budget and a realistic timeline before moving forward.
