Timberwood Park isn’t like most of the San Antonio metro. The custom homes sit on 1- to 5-acre wooded lots, the HOAs are strict, and the terrain rolls. An ADU here is a different project than one in a dense infill neighborhood: you’re balancing generous acreage against tight aesthetic rules, rocky ground, and a climate that punishes cheap cooling and drainage decisions. We’re Seedling ADU San Antonio, led by Ben Ortega. We build accessory dwellings, garage conversions, and home additions in Timberwood Park with written pricing before any work starts and the 365-Day Done Right Promise behind every job. Call (210) 981-6358 to talk through what your lot can hold.
Why Timberwood Park Homes Are Different
Timberwood Park’s housing stock is mostly custom and semi-custom homes built from the 1980s onward, with limestone and brick exteriors that read as distinctly Hill Country. That matters when you add an ADU: the new structure has to look like it belongs. A detached unit that ignores the main home’s materials or roofline will draw immediate HOA attention – and rightly so, because the covenants here are specific about aesthetic continuity and setbacks.
The terrain adds another layer. Lots along the Hill Country edge of Timberwood Park often slope noticeably, and dense oak cover means a buildable site isn’t just about where you want the unit. It’s about where a level spot exists that still respects Bexar County’s 25-foot tree preservation rules and impervious cover limits. We spend more of the early planning phase on siting here than we do in flatter parts of the metro, and that’s the right call: moving a foundation even eight feet on a sloped, treed parcel changes drainage, utility runs, and the final look of the project.
Hot, humid summers are the third piece. Any ADU in Timberwood Park needs high-efficiency cooling, storm-rated windows, and drainage that handles the sudden heavy thunderstorms this area gets. Those aren’t optional upgrades here; they’re what keeps a unit livable in August and bone-dry after a spring storm.
Our Main Timberwood Park Services
Most Timberwood Park homeowners call us about three things: adding square footage to the main home, converting an existing garage into living space, or building a new detached ADU. Each has its own page with full detail, including local pricing and what the process looks like inside your home.
Home Addition Contractor in Timberwood Park
Home additions in Timberwood Park tend to be more involved than in a standard subdivision, because the existing homes are often custom builds with limestone or brick exteriors that are expensive to match poorly but straightforward to match well if you plan early. Material matching, foundation work on sloped lots, and roofline continuity are the three things that decide whether the addition looks like it was always there. We walk the site with you before pricing anything. Full detail is on the Home Addition Contractor in Timberwood Park page.
Garage Conversion Contractor in Timberwood Park
Converting a garage into a bedroom, office, or in-law suite is a natural fit for Timberwood Park, where most homes have generous garage footprints already under the main roofline. The work centers on insulation, cooling, egress, and flooring – taking a space built for cars and making it comfortable for people. HOA rules here sometimes restrict how much the front elevation can change, so we plan garage conversions to keep the exterior looking residential. The Garage Conversion Contractor in Timberwood Park page covers the process and cost.
ADU Builders in Timberwood Park
A detached ADU in Timberwood Park is effectively a new small home on your lot, and the lots here are big enough to do it well. The work is finding the right site among the oaks, managing the foundation on rocky or sloped ground, and designing a unit that passes HOA review while keeping long-term comfort in mind. We work with prefab brands like Abodu, Cover, and Tuff Shed as well as stick-built construction, so the design doesn’t fight the lot. See the ADU Builders in Timberwood Park page for what a project typically costs and how we phase it.

Every project we price includes a written line-item quote before work begins, and that number doesn’t change once the crew arrives.

FAQs About ADU Company in Timberwood Park
The HOA review comes before permitting, and it’s where most Timberwood Park projects live or die. We prepare the design submittal, including material samples, roofline drawings, and site plans showing setbacks, then walk it through review alongside you. Expect the HOA step to take two to six weeks, with the design fee in our pricing table covering the documentation, not the HOA’s own application fee.
Usually yes, but it changes the foundation approach and the budget. Sloped lots may need a pier-and-beam foundation, retaining, or additional grading, and the county’s impervious cover rules mean you can’t just pave over the grade problem. We’ll evaluate your specific site before quoting, and we’ll tell you plainly if the slope makes a particular unit type impractical. Call (210) 981-6358 to schedule a site walk.
A prefab ADU can be placed in four to seven months from contract to completion, including design review. A custom stick-built unit or a home addition typically runs six to twelve months. The wild card in Timberwood Park is the HOA review window, which we sequence early so it doesn’t stall the build later. For an exact timeline on your lot, call (210) 981-6358 – estimates are free.
