Expand Your Space
A home addition offers a multitude of benefits, starting with the immediate increase in living space tailored to your specific needs. Whether accommodating a growing family, creating a home office, or adding room for recreation, the additional square footage enhances your overall living experience.
Beyond the immediate advantages, a well-executed home addition can significantly boost your property's resale value, providing a return on investment. It also offers a cost-effective alternative to the expenses associated with relocating to a larger home, allowing you to stay in your preferred neighborhood and adapt your living space to changing circumstances..
Redesign Your Home
A thoughtfully designed home addition contributes to improved functionality and aesthetics. Customization allows for seamless integration with existing architecture, maximizing natural light and creating a brighter, more inviting atmosphere. Whether enhancing your current lifestyle or preparing for future needs, a home addition is a strategic investment that transforms your living space to align perfectly with your evolving preferences and requirements.

You’ll connect with Dylan, Tectonic’s founder, to discuss your project goals, vision, and budget. He’ll walk you through our Integrated Vision System™, so you understand exactly how we design and build. You’ll also receive a high-level remodeling estimate based on similar projects, giving you a clear starting point.
This is your opportunity to ask questions, share inspiration, and get expert insights on the feasibility of your remodeling ideas.

Yes! After our discovery call, we’ll schedule a complimentary site visit with Dylan and our design team. This allows us to evaluate your space, understand your remodeling goals, and ensure our approach aligns with your needs. During the visit, we’ll take measurements, assess structural and design considerations, and discuss potential challenges or opportunities. This hands-on evaluation helps us provide a more accurate estimate and project scope before any contracts are signed. Our goal is to give you confidence in your decision while laying the groundwork for a successful project.
-
Traditional construction requires hiring a designer, architect, and builder separately, often leaving you to manage communication, timelines, and budgets on your own.
With design-build, everything is handled in-house—one dedicated team oversees your entire project, ensuring seamless execution, clear communication, and total accountability with services from start to finish.
This streamlined approach eliminates gaps between design and construction, reducing costly changes and unexpected delays. By working with a single team, you’ll have a clear plan from the beginning and a more efficient, stress-free experience. From initial design to the final build, every step in our design build services is coordinated to bring your vision to life smoothly and efficiently.

Timelines vary based on scope and complexity, but our Integrated Vision System™ ensures a clear schedule and proactive management to keep your project on track.
During the planning phase, we’ll provide a detailed timeline so you know exactly what to expect. Our structured process minimizes delays and allows us to anticipate challenges before they arise, keeping your project moving forward efficiently.
-
Our fixed-price contracts outline all costs upfront, including materials, labor, and project management, eliminating unexpected expenses. This means no surprise charges or shifting estimates - just a clear, transparent budget from day one. We include detailed specifications for every aspect of your project, ensuring quality standards and expectations are met. By defining costs and scope early, we help you make informed decisions while keeping the project financially predictable.
-
Unlike cost-plus contracts, which can fluctuate, our fixed-price model ensures financial predictability, so you know exactly what to expect. With cost-plus pricing, homeowners are often responsible for covering unexpected costs and overages, which can lead to budget uncertainty. A fixed-price contract removes that risk by locking in costs upfront, keeping the price you agree on the price you pay. This approach gives you greater peace of mind and allows you to focus on your new space rather than worrying about cost overruns.
