NS Design and Build helps Denver homeowners expand and improve their homes with carefully planned home additions. Whether you need a second story, a ground-level bump-out, a garage addition, or an ADU for rental income or multigenerational living, our design-build team manages the entire project. We combine transparent pricing, experienced project management, and licensed, bonded, and insured construction services to create additional living space that supports your budget, property, and long-term goals.
We visit your property, review the existing footprint, discuss your goals, and evaluate how the addition may affect your home’s layout and square footage.
Our team assesses the existing structure, foundation, zoning considerations, and potential engineering requirements.
We create a functional layout, define the project scope, discuss finishes, and prepare a clear preliminary budget.
We prepare permit applications, coordinate engineering documents, address plan corrections, order materials, and develop the construction schedule.
Our crews complete foundation, framing, roofing, mechanical, electrical, plumbing, and interior work while keeping the site organized and providing regular updates.
We coordinate required inspections, complete punch-list items, review the finished addition with you, and provide applicable project documents and warranty information.
We build second-story additions, pop-top conversions, ground-level bump-outs, full-home additions, accessory dwelling units, and garage additions. Each project is designed around the existing structure, available property space, and the homeowner’s goals.
Our design-build process begins with a free consultation and property walkthrough to define the project scope, goals, and budget. We then develop plans, coordinate with structural engineers and designers when needed, obtain permits, and manage construction through the final inspection. This approach keeps communication, decision-making, and accountability within one team.
Yes. We prepare permit applications, coordinate required plans and documentation, communicate with local building departments, and respond to plan corrections. For more complex additions, we also coordinate directly with licensed structural engineers and include their documents in the permit submission.
An ADU or properly designed second-story addition may create a separate living area that can be used for long-term rental income, short-term stays where permitted, or extended family accommodations. We can plan for privacy, separate entrances, kitchens, bathrooms, and independent utilities when appropriate.
The cost of a home addition depends on its square footage, structural complexity, foundation requirements, materials, mechanical systems, and finish selections. A small bump-out will generally cost less than a complete second-story addition or detached ADU. We provide a clear estimate after the consultation and feasibility review.
Yes. We design and construct second-story additions and pop-top conversions for single-story homes. Before moving forward, we evaluate the foundation, framing, roof structure, and other structural components to determine whether upgrades or reinforcements are needed.
Timelines vary based on the size of the addition, permitting requirements, structural work, and material availability. Smaller bump-outs may require several weeks of construction after permits are approved, while second-story additions, full-home expansions, and ADUs may take several months from design through final inspection.
Many home additions require a structural engineer to confirm that the existing home can safely support new loads or to design foundation, wall, beam, and framing reinforcements. NS Design and Build coordinates with licensed engineers and includes their plans in the permit application when required.
A well-designed addition can increase usable square footage, improve functionality, and raise the overall value and marketability of the property. Second-story additions and ADUs may offer significant value when they provide additional bedrooms, bathrooms, living space, or rental income potential.
Yes. NS Design and Build offers a free property walkthrough and estimate for Denver homeowners considering a home addition. During the meeting, we review your goals, evaluate the available space, and explain the next steps for design, permitting, budgeting, and construction.
