A modern timber-clad house at dusk with warm light in the windows

Houses that hold still.

A design and build studio in the Upper Valley, making a few houses a year and finishing every one of them ourselves.

The studio

Most houses are designed by one firm, priced by another, and built by a third. Every hand-off loses something: a detail, a dollar, a reason. We put the architect and the builder in the same room from the first sketch to the last coat of oil, so the house that gets built is the one that was drawn, at the price that was agreed, by the people who promised it.


Three houses, recently finished.

A living room with a polished concrete floor and floor-to-ceiling glazing

Ridge House, Kingsbridge

A single-storey house set into a north-facing slope, with a polished concrete floor that runs unbroken from the entry to the terrace. Glazing was sized to the view, not the catalogue.

New build, 3,400 sq ft
$1.8M to $2.2M
2025
An oak kitchen with a stone counter and brass tap

Orchard Kitchen, Lower Vale

The original timber frame was kept and exposed. Oak cabinetry, a single stone counter, and one brass tap. Nothing in the room was bought twice.

Whole-house renovation, 1890s farmhouse
$650K to $800K
2024
A dark-clad cabin set among trees

Blackwood Cabin, Hollins Reach

Charred larch cladding, a steel roof, and a plan that fits between the existing trees. No tree was removed to build it.

Guest house and studio, 1,100 sq ft
$480K to $560K
2024

Design and build, under one roof.

01Design

One architect and one builder sit at the same table from the first sketch. Cost is a design input, not a surprise at tender. You see a fixed price before a drawing is finished.

02Build

Our own carpenters and a small circle of trades we have worked with for a decade. One site lead, one weekly walk-through with you, and a schedule that is written down and kept.

03Care

We return at six months and at two years to check the house is settling as it should. Doors are adjusted, timber is oiled, and anything that is ours to fix is fixed.

The studio

“We build three or four houses a year. That number is the whole business plan. It is how many we can stand behind.”

Tessa Marrow, founder and principal. Eleven people: four architects, five carpenters, two who keep the rest honest.
