Design · Systems by the House

Intelligence that disappears into the architecture.

Automation, lighting schemes, audio, and heating controls — designed with our interior studios from the first brief. The brains behind the HoWA Assistant as well.

House AI.

Specialist partner · UK-wide

House AI is our specialist partner for anything electrical, automated, or intelligent inside a home. They build systems that are meant to be invisible: lighting that does the right thing without thinking about it, audio you don't see, heating that learns.

They work with our design studios from early concept so the technology doesn't feel bolted on. House AI also powers the back-end of the HoWA Assistant — the model behind the diagnostic.

Before you commission, some questions.

How is HoWA different from hiring a designer directly?

HoWA matches, configures, and holds the record, and you keep the designer relationship.

Can I buy a package before a consultation?

Yes. Room Edit is Pay Now. Full House Edit is consultation-first.

What does “House Approved” sourcing mean?

A curated roster of makers and suppliers vetted by the House for craft and quality.

Does every action live in HoWA?

Every meaningful one. The living record is the point.
