Backyard ADU Studio

Purpose & footprint

• A detached backyard ADU studio on a Texas lot, seen from an exterior three-quarter angle at dusk: crisp soft-white board-and-batten siding under a simple gabled composition-shingle roof, a full-lite black-framed glass door and a wide black-framed window revealing a warmly lit efficient interior with a compact oak kitchenette, a daybed, and a small desk zone, a cedar-wrapped entry surround with a single step, a gravel-and-paver path crossing a bermuda lawn from the main house, a mature live oak overhanging one corner, black gooseneck lights just switched on over the entry, the interior glow contrasting the cool dusk sky.

Design details

• Detached backyard ADU studio — roughly 400 sf
• A detached backyard studio at dusk: crisp soft-white board-and-batten siding under a simple gabled composition-shingle roof, with a full-lite black-framed glass door and wide picture window revealing a warmly lit interior. Inside sit a compact oak kitchenette, a daybed, and a small desk zone. A cedar-wrapped entry surround with a single concrete step anchors the door, black gooseneck lights glow over the entry, and a gravel-and-paver path crosses the lawn from the main house under a mature live oak. The intent is a real, permitted second space — guest suite, office, or studio — that earns its keep.

Project assumptions

• Roughly 400 sf studio with kitchenette; no full bath in scope
• Utilities extended from the main house within trench reach
• Lot meets setback and coverage rules for a detached ADU
• Tree protection for the existing live oak during work
• Appliances at a compact mid-spec allowance

Options

• Keep sound existing components where compatible.
• Compare stock, semi-custom and custom selections before ordering.
• Confirm samples in the room’s natural light.

Trades & site requirements

• Carpentry and finish installation; confirm any specialist trade needs on site.
• Check access, working clearances, occupied-home protection, waste removal and delivery space.
• Check substrate condition, moisture and concealed services before installation.

Permits & engineering

• Structural capacity, setbacks, drainage, utility capacity and any required engineering remain unverified. Do not treat the concept as a construction drawing.
• Confirm anchoring, concealed wiring and applicable fire-clearance requirements.

Sequence & duration

• Measure and inspect → confirm scope and selections → check approvals → order materials → protect the site → install → inspect and finish.
• 4–8 months
• Installation window excludes design, approvals, fabrication lead times and unforeseen repairs.

Estimate basis & inclusions

• $90,000–$136,500
• Adjusted sample planning allowance. Feasibility at this budget has not been verified against current supplier and trade quotes.
• Covers only the stated quantities and installation scope; decorative objects and adjacent rooms are not included.
• Site condition, access, material choice, waste, permit requirements and concealed damage can change the written quote.

Exclusions & unknowns

• Exact product selection and current availability are unknown.
• Concealed damage, structural repair and utility relocation are excluded unless explicitly scoped.
• Permit and engineering fees, taxes and contingency require confirmation; they are not guaranteed included.
• Furniture, styling and loose appliances are excluded unless explicitly listed.

Care & maintenance

• Inspect exterior seals, drainage and fasteners seasonally; maintain finishes to the manufacturer’s schedule.
• Final maintenance instructions depend on the products selected.

Next steps

• Bring room dimensions and existing-condition photos to a walkthrough.
• Confirm a written scope, selections, permit needs and site-specific quote before work.
