Denver Home Additions Built with Engineering Precision

Expanding a historic property requires a balance of technical expertise and creative vision. Established in 2003, Squareroot is a Denver based general contractor that combines the skills of a Professional Engineer and an Urban Planner to provide a practical approach to building site challenges. We specialize in the city-close neighborhoods including Wash Park, the Highlands, and Congress Park, where we create Denver home additions that modernize your lifestyle while protecting the soul of the original 1920s architecture. 

Plan Your Addition

Structural Mastery for Complex Urban Perimeters

While many builders treat structural engineering as a subcontracted phase, our firm is led by a licensed Professional Engineer who applies technical rigor to your project from the first walkthrough. This background allows us to solve complex issues involving foundation stability and structural integrity that other firms might view as roadblocks.

Vertical Home Additions

When your property has a limited footprint, moving upward is often the most effective strategy. We specialize in vertical expansions, also known as pop-tops, for historic bungalows that require careful structural analysis to support a second story. Our engineering-first approach identifies site challenges early, enabling us to add significant square footage while respecting the original character of your home.

Horizontal Home Additions

Horizontal expansions, also called bump-outs, are ideal for creating master suites, expansive kitchens, or additional living areas that flow naturally from the existing floor plan. We focus on seamless integration to make the new construction appear as though it were part of the original design. Our team manages the technical complexities of foundation work and city-close zoning to make the process predictable and transparent.  

Accessory Dwelling Units (ADUs)

For the infill visionary, a detached addition provides a blank slate for luxury modern amenities or multi-generational living. We design these structures to respect the fabric of the neighborhood while incorporating features such as home gyms and small but highly efficient kitchens. Our urban planning expertise allows us to navigate the specific regulatory requirements of the Denver metro area.

A Disciplined Process Grounded in Transparency

Our Built for Good mission means acting as your ally to guide you through the involved process of expanding your home. We remove the guesswork by combining thorough preconstruction planning with real-time project data. Through the CoConstruct platform, you have total access to the financial and operational health of your project.  

This system provides the organization and precision that professionals expect during a complex build. 

Initial Alignment

We work with you to define the project scope and evaluate your property. This includes on-site sketches and a ballpark estimate to make certain your vision aligns with the budget and site requirements. 

Live Budget Tracking

You have constant access to your financial data within the CoConstruct portal. This allows you to see exactly where your capital is allocated throughout the build.

Real-Time Progress

Monitor the daily health of your project through detailed schedules and photo logs. Our field teams upload progress notes daily to provide a clear record of the craftsmanship in your home. 

Direct Accountability

Every decision, contract, and change order is documented within the platform. This maintains a relationship based on trust, mutual respect, and professional integrity.
