Interior architecture

Rooms that
hold their value.

Interior architecture and bespoke joinery for houses between two and eight million — drawn to the millimetre, costed before anything is ordered, and detailed so the building works as well in year ten as it did in week one.

The service

Four stages, one drawing set.

Every commission runs on the same spine: survey, design, specification, install. You see the cost of each stage before the next one begins.

A measured survey of every room, then the honest conversation about how the house is actually used.

  • Measured survey and levels
  • Light and aspect study
  • Written brief and fixed fee

Specification

The millimetre is the product.

A kitchen that fits its room, a stone upstand set out from the window reveal, a shadow gap that stays straight after two winters. Drawings make the difference; the photography just records it.

The finish studio

Choose the room. Read the cost.

Three decisions carry most of a scheme. Change any of them and the room, the specification and the estimate change with it.

In their words

“You cannot retrofit calm into a room. You can only draw it properly at the start, and then protect it on site.”

Build sheet

How it was made.

Every build is hand-written, not templated: a bespoke layout system, custom motion, and content authored for the business it belongs to.
