Detached Guest House in Keller, TX
The Project
The homeowners in Keller's Hidden Lakes community reached out after a health event with one of their parents made it clear that an independent but close-by living arrangement was needed — and needed soon. Their half-acre lot had plenty of room for a detached structure; the question was how to build something that would genuinely work for aging-in-place, not just check a code compliance box.
We designed a single-level, 920 sq ft guest house with aging-in-place priorities built into every decision: a zero-step entry from the covered walkway connecting to the main home, a curbless shower with built-in grab bar blocking, 36-inch doorways throughout, and a full kitchen designed at accessible counter heights. The utility connections were run from the main home's systems, with separate metering for transparency on costs.
Exterior design was a deliberate match to the main home's stone-and-stucco facade so the guest house reads as an intentional part of the property rather than an afterthought. The covered breezeway connecting the two structures was a custom addition the family requested — it's now described as the feature they use most.
The project was permitted through Keller Building Services and completed in seven months from design kickoff to certificate of occupancy.
Scope of Work
“They designed something that actually works for my mother-in-law — not just something that technically counts as a guest house. The covered walkway was their suggestion and it was the right call.”
