What can you build?
Property boundaries, setbacks, easements, drainage, and existing site conditions can affect where an addition can go.
More room can change how your family lives. Getting there takes more than a floor plan. We bring design and construction together to consider your existing home, your property's limitations, and the approvals that may shape what's possible.

An addition is a major investment in the property you already own. Understanding the physical, financial, and regulatory constraints early helps you make better decisions about the space.
Property boundaries, setbacks, easements, drainage, and existing site conditions can affect where an addition can go.
Foundations, rooflines, existing walls, floor elevations, and utility connections influence how new space joins the house.
Square footage is only part of the picture. Structural changes, site access, mechanical systems, and finish selections also matter.
Building permits, zoning, HOA architectural guidelines, deed restrictions, and historic district rules may apply. Requirements depend on the property's location and project scope.
Start with your goals and an assessment of the existing home. Surveys, engineering, or further research may be needed before the project can be fully defined.
Every addition begins with a different need. These projects offer a closer look at how new spaces can become part of an existing home.
An additional living space and swimming pool behind the main residence in New Braunfels, TX. Inspired by English hunting lodges, family and friends can stay comfortably for any period of time.
Always the hosts over the holidays, this family wanted more space for comfortable entertaining by converting their existing patio to a living room.
Sometimes you need more space, but moving isn't what you want. An addition can make room for the people, routines, and experiences that matter to you.
Holidays, family dinners, and weekends with friends feel different when everyone has a comfortable place to be together. An expanded living area can make those occasions easier to host.
An aging parent moving closer. Adult children returning home. Grandchildren staying longer. A private suite or additional bedroom can give everyone more flexibility and independence.
You may love your neighborhood, your property, and the memories you've made there. Adding usable space can help you plan for the years ahead without starting over somewhere else.
The reason for adding on is personal. The plan should start there.
Talk About Your Project ↗
A Shaw Project Specialist visits your home to understand what you want to accomplish and review visible existing conditions. With a construction background, they can discuss practical possibilities and identify questions about the property, structure, and required approvals. Surveys, engineering, or additional research may be needed before feasibility, scope, and pricing can be confirmed.
Adding square footage means working with the house you already own, the property it sits on, and the requirements that apply to it. Those factors belong in the conversation before a design is finalized.
Foundations, existing walls, rooflines, drainage, and utilities can influence what's practical. Some conditions require engineering or further investigation.
Exterior materials, floor elevations, windows, and room transitions deserve attention so the addition feels like part of the existing house.
Depending on the property, construction may require permits, plan review, inspections, and separate HOA or historic approvals. These are distinct requirements.
Work may affect occupied areas of the home. Access, sequencing, utility interruptions, and inspections can all influence how the project is scheduled.
The homeowners had plenty of square footage. What they needed was a better place to gather. Their existing covered patio offered an opportunity to bring the communal spaces together.
The existing covered patio before its conversion into an enclosed living room.
Hosting family and friends is an important part of life for these homeowners. Their communal rooms were spread throughout the house, making it harder to gather in one comfortable space.
They wanted to convert an existing covered patio into a proper living room, creating more usable space while keeping the character of the original house.
The project involved more than enclosing a patio. Shaw's scope included structural foundation work, framing, roof modifications, and the required permitting and inspection process.
The team also worked through how to connect two different ceiling heights, match the existing Saltillo tile, and carry the home's exterior character into the addition.
The homeowners wanted the Saltillo tile to continue through the new living room. Matching the existing material helped the rooms feel connected. This particular tile is discontinued but the supervisor on this job, with his extensive background in tile, was able to source an exact match.
The original house and the new living room had different ceiling elevations. Shaw developed a transition that accommodates those differences while keeping the connection between spaces visually cohesive.
The addition called for cedar siding, paint, and windows selected to closely match the original home. The goal was to make the new construction feel like a natural continuation of the exterior.
A successful addition isn't just about adding square footage. It's about making the new space work with everything around it.
Discuss Your Addition ↗Permits, property restrictions, and approval requirements vary by location. These official resources are a useful starting point for homeowners planning an addition in the San Antonio area.
A few questions worth asking early, while your plans are still taking shape.
Yes. The City of San Antonio requires permits for room additions. Additions over 1,000 square feet and second-story additions require residential plan review. Electrical, plumbing, or mechanical permits may also be necessary depending on the work.
Yes. If your property is subject to deed restrictions or HOA architectural guidelines, the proposed addition may require separate review and approval. Government permits do not replace private architectural approval. Check your community's governing documents before finalizing plans.
Not necessarily. Applicable setbacks, easements, zoning requirements, and other property restrictions may limit where an addition can be built. A current survey and site-specific review can help establish the available building area.
Engineering requirements depend on the scope and permitting jurisdiction. For San Antonio residential additions requiring full plan review, the City requires a foundation plan prepared by a licensed engineer. Other structural conditions may also call for professional engineering.
Designated historic properties and properties within certain historic districts may require additional review and a Certificate of Appropriateness for exterior changes. Verify the property's designation before developing an addition plan.
Requirements depend on the property's actual jurisdiction. Unincorporated Bexar County generally does not use the same mandatory residential building-permit process as the City of San Antonio. However, floodplain, septic, driveway, and other development requirements may still apply. Other incorporated cities have their own rules.
A note about local requirements: These resources are provided for general planning purposes. The permits and approvals required for an individual project depend on its location, scope, site conditions, and applicable private restrictions. Requirements should be verified with the relevant authorities before construction.

From construction timelines to matching existing materials, these are some of the questions homeowners bring to us.
Timelines vary based on size and complexity. We plan the construction sequence to get the new structure weather-tight before opening walls where practical, helping reduce disruption to your daily life.
An addition involves more than building new square footage. The new structure has to connect to the existing home, which can require foundation work, roof modifications, utility changes, and careful transitions between old and new materials. Those conditions make the cost per square foot different from building on an empty lot.
We coordinate the planning and construction work involved in an addition, including required engineering and permits as applicable to the project. The specific requirements depend on the property's location and proposed scope.
That's part of the design conversation from the beginning. We look at rooflines, exterior materials, flooring, windows, and the transitions between rooms. Our Bluffview addition, for example, involved matching existing Saltillo tile and cedar siding while working with different ceiling heights.
Yes. Property setbacks, easements, drainage, existing structures, local building requirements, and HOA rules can all affect where an addition is possible. We begin reviewing those considerations early, though surveys or additional professional evaluations may be necessary.
