The current plan
The casita is now joined to the main house by a hallway connector, and a cinema has been added: about 9,700 square feet in all, planned as a pre-market spec home. The animation walks the updated plan; the sheets are the main level, the site and the roof.

In partnership and collaboration with designtank (architecture) and House of Form (interiors). Updated schematic plan, 1 October 2026; plans will change.
Architecture · designtank · September 2026
The first concept
The architects at designtank presented the first concept on 16 September 2026: a two-storey courtyard house wrapped around the pool, with the casita and garages on the street side. The renders and sheets below are from that review; the plan above supersedes it.

The idea
The existing house gave nothing back to a site that deserved it. designtank's scheme turns the whole property toward the mountain: a low house of stone and plaster under tile roofs, laid out on a single axis that runs from the entry court, through the great room, down the length of the pool to the view. Loggias with stone columns and outdoor fireplaces sit on both sides of the water, so the house lives outside for most of the year.
Inside, steel-and-glass walls open the living room and great room to the court, and the kitchen and dining run along it. House of Form is designing the interiors on the same palette: limestone, plaster, oak and iron. The earlier 2024 study, a gabled modern scheme with glass garages, is shown further down.
Program
Main house with the casita now joined to it by a hallway connector, a cinema, garages, a sport court, and outdoor living sized for a family or a full house of guests. As of October 2026 the house is planned as a pre-market spec home. The project is self-managed by our own foreman, which is how we hold hard cost well under replacement-cost benchmarks.

Gabled great room, glass garages, pool and outdoor living
The in-house studio's 2024 study on the same site: a gabled, glass-fronted great room at the center, two glass-door garages on the entry court, a vaulted living room with a stone fireplace wall. It set the program the new scheme builds on.
