Across Silicon Valley, builders and designers working with tech-industry clients tell us they're highly engaged; some even want the full set of construction documents, sometimes 160 pages long, and return with questions about nearly every line.

Many are also younger than the typical custom-home client. Architect Mahya Salehi says they tend to build wealth earlier in their careers than doctors or lawyers do. Yet their taste in the house itself can be surprisingly low key, because many want a home that feels simple to live in, with the sophisticated systems tucked out of sight, often in the mechanical room.

Tech wealth is also reshaping the region’s housing market. In San Francisco, 144 homes sold for at least $1 million over asking in the first half of 2026, compared with just eight during the same period a year earlier. And only a small share of homes on the market met these buyers’ needs for larger family houses. With little open land left in Silicon Valley, custom homes often have to fit small or irregularly shaped lots and work within strict zoning limits.

This guide brings together four Silicon Valley case studies showing how design teams responded to those constraints, along with two features on how architects and builders are adapting their processes to highly engaged clients. Their experiences also offer lessons for working with tech-industry clients in other markets.
