What we were working with
A fully custom ADU in Rancho Cucamonga: a living room that opens to the yard at the corner, white oak details and a custom concrete floor.
How we handled it
Underground plumbing and an 85-yard pour in November 2024, framing that month and trusses in December. In February 2025 the Windor Systems pocket corner door went in, the piece that opens the corner of the living room to the yard. Drywall followed in March, kerf white oak jambs and doors with a recessed baseboard detail in April, the custom concrete floor and cabinets in May, and the quartz counters with a gold faucet by July.
Built with Windor Systems (pocket corner door).
