The combined master bath and lounge at David Howell Design's house in San Miguel de Allende, Mexico, features a custom cast-in place concrete vanity and tub. Vintage sofas surround a custom maple table by the house's owner.

In the living room, Houshmand's maple table and cherry sofas, all custom, gather on a locally made cotton flat-weave, near another oil on canvas by Perlet.

Mesquite trees shade a concrete fountain in the courtyard, with its double-sided fireplace.

Reeds form the roof of the pool pavilion.

The kitchen's mesquite stools pull up to an island surfaced in local glazed ceramic tile. The steel pendant globe is custom.

On the dining portico, mesquite chairs surround Houshmand's custom willow table.

The courtyard's pair of mesquite trees were existing.

The headboard in a guest room was made from two mesquite doors.

The living room's 10-foot-high steel-framed windows were fabricated on-site.

A carved stone sheep's trough now serves as the sink in a guest bathroom.

Tinted plaster clads the exterior.

In another guest room, Houshmand's custom bed and maple headboard back up to a window dressed with cotton curtains and sheers.

Stone pavers surround the concrete pool.

Greenery is watered by a natural spring.

Sunbrella acrylic covers the banquette cushions in a rooftop pavilion, where Houshmand sits with friends.
