Residential Projects Backed by Real Work in San Marcos
San Marcos is where our featured project stands: a 3,100 square foot residence reimagined from the slab and studs upward over sixteen months, completed in June 2026. That project reflects how we approach every San Marcos job: careful planning, structural honesty, and finish quality that holds up. Whether you are building new or transforming an existing home, Riverbend brings that same standard.

Building In and Around San Marcos
San Marcos, Texas sits where the Hill Country meets the Interstate 35 corridor, with the spring-fed San Marcos River at its heart. The city has grown quickly, but its established neighborhoods hold homes with real character, and the hills west of town offer acreage that feels like deep Hill Country while staying close to everything.
Projects inside the city run through municipal review, while properties in the county follow a different path, often with wells and septic in the plan. Established neighborhoods can carry their own considerations, and older homes bring the usual honest questions about foundations, plumbing, and electrical. We sort out which of these applies to your property before design decisions harden into costs.
Our featured project here taught us the value of that discipline firsthand. The home's foundation was professionally leveled before any finish work began, the rear elevation was reengineered for expansive glass, and both HVAC systems were replaced with complete new ductwork. None of that shows in a photograph, and all of it is why the finished home works as well as it looks.
We walk San Marcos properties with homeowners before plans are final, so structure, systems, and setting are part of the plan from the start.
What a San Marcos Project Typically Involves
In our published planning ranges for the broader Hill Country market, new custom construction typically runs $350 to $650 per square foot at comparable finish levels. A substantial whole-home remodel typically runs $400 to $800 per square foot of remodeled area, and targeted single-area remodels typically run higher per square foot because the work is concentrated and finish-heavy.
On schedule, building new typically runs 14 to 20 months, and a substantial whole-home remodel typically runs 12 to 24 months. Our featured San Marcos renovation ran sixteen months, which is exactly the range honest planning would have predicted for its scope.
On remodels, we plan honestly for hidden conditions and recommend carrying at least a 20 percent contingency on top of base scope. For homes built before 1990, 25 to 30 percent is more realistic. The contingency belongs to the project and to you, and any unused portion stays yours.
Every figure above is a planning range, not a quote. The property, the scope, and the finish level decide the real number.
The Proof Is Standing in San Marcos
Most builders can show renderings. We can show a finished San Marcos home, transformed from the slab and studs upward: custom lime-washed exterior, a 10-foot 7-inch iron pivot entry, black Andersen windows and sliders, custom white oak cabinetry around a Wolf cooking suite, and a spa-inspired primary bath.
The project was a true team effort, with architecture by Alexander Ridgway of Verandah Residential Architecture, interiors by Amy Kennedy Design, and engineering by BEC Engineering. Riverbend served as builder and general contractor, coordinating every structural, mechanical, and finish decision.
That team model is how we run every substantial project: the right specialists, coordinated by one accountable builder, with decisions documented and the homeowner informed at every stage.
If you are considering something similar for your own San Marcos property, the full project is documented in our portfolio, and we are glad to talk through what your home could support. Most first conversations start with coffee and a tape measure.
