Our Home Building & ADUs Services in Austin, TX

Custom single-family home construction

Ground-up homes built from your architect's drawings, or we bring in a designer if you are not that far along. Most of our custom work sits inside Austin city limits and out through Dripping Springs, Lakeway and Bee Cave.

Detached ADU and guest house construction

Standalone units with their own foundation, utility runs, and inspections. Austin's ADU rules are more permissive than most Texas cities, which is why a second unit pencils out here when it would not elsewhere.

Garage conversions and above-garage units

Converting existing garage space into conditioned living area, or adding a unit above it. Usually the least expensive route to a second dwelling on an Austin lot, because the foundation is already there.

Site plan review and City of Austin permitting

We file and carry the permit set under our own registration. Impervious cover, setbacks, tree ordinance, floodplain and utility taps are handled on our side, and we answer the city's comments.

Foundation, framing and structural work

Slab or pier and beam, engineered for your specific lot. Central Texas clay moves with the seasons, so foundation design gets sized to your soil report.

Full MEP rough-in and finish-out

Electrical, plumbing and HVAC from rough-in through trim and fixtures, with every trade held on our subcontracts and scheduled against one calendar.

Exterior envelope, roofing and siding

Weather barrier, windows, roofing and cladding detailed for Austin heat, UV load and the hail that comes through most springs.

Interior finish carpentry, cabinetry and millwork

Built-ins, trim, stair work and cabinetry. Selections get locked early so a twelve-week cabinet lead time never becomes a hole in the schedule.

Driveways, walkways and site concrete

Approaches, flatwork, patios and hardscape, poured once the heavy equipment is off the site so nothing gets cracked before you move in.

Final inspections and certificate of occupancy

We schedule the inspections, close the permit out, and hand over the certificate of occupancy along with warranties and as-builts.

Home Building & ADUs projects across the Austin metro

Building new in Austin means dealing with the city before you deal with a single stud. Site plan review, impervious cover limits, setbacks, tree ordinance, floodplain, utility taps — the permit set is its own project. We are a registered general contractor in Austin and we pull our own permits, which means the person managing your schedule is the same person answering the city's comments.

On custom homes we work from your architect's drawings or bring in a designer if you do not have one yet. Either way you get a real scope and a real budget before we break ground, not a per-square-foot guess that moves once framing starts. Allowances are written down. Change orders are priced before the work happens, not after.

ADUs have become the most practical way to add value to an Austin lot, and the rules changed in your favor — but they are still full construction projects with their own foundation, utilities, and inspections. Whether you are building a rental unit, a guest house, or a place for family, we build them to the same standard as the main house, and we sequence the work so the primary residence stays livable.

One general contractor, one contract, one schedule. We carry the subs, the inspections, and the punch list, and you get a single point of contact from the first site visit through the certificate of occupancy.

Reviews

Reviews from Our Customers

From homeowners, investors, and commercial clients across the Austin metro.

“

“We use them for every pre-listing make-ready now. Had them repaint the entire interior of a 4-bed listing in Avery Ranch — neutral tones, clean lines, two coats throughout. Done in three days and the house showed like new construction. Went under contract opening weekend.”

Marcus T.

Round Rock, TX — Interior Painting

“

“Painted our entire downstairs — living room, kitchen, hallway, and half bath. They matched the existing trim color perfectly and were completely done in two days. Not a single drip on the floors.”

Nicole W.

Mueller, Austin, TX — Interior Painting

“

“Had them replace carpet with LVP in a rental property between tenants. They coordinated around the tight turnover window, finished two days ahead of schedule, and the floors look amazing. New tenants signed the lease the day they toured.”
