Board-Formed Concrete · Est. 2009

We build only in raw concrete.

FORMWORK is an architecture studio working in a single material - board-formed, in-situ concrete. Every wall carries the grain of the timber that shaped it. No cladding, no render, no apology.

01 - Ethos

Honest to the formwork that made it.

We don't disguise structure. The mark of the timber boards, the tie-rod holes, the seams of each pour - these are the architecture, not flaws to be hidden beneath a finish.

A.

One Material

Board-formed, cast-in-place concrete - and nothing else. Constraint is the discipline. A single material forces every decision into the open.

B.

The Board Is the Drawing

Timber is selected, sequenced and aligned plank by plank. The grain transferred to the wall is designed as deliberately as any plan.

C.

Cast Once

There is no second take with in-situ concrete. We rehearse the pour in full scale before it happens. Precision is the only safety net.

02 - Selected Work

Walls that remember the timber.

Houses, chapels, galleries and civic rooms - each one a study in what a single material can hold.

Residence
Ticino, Switzerland

House on the Grain Line / 2023

A four-bedroom house cast as a single continuous wall that folds to form every room. Larch boards, laid horizontally, run unbroken across forty metres of façade.

TypePrivate House
Pours11 lifts
FinishAs-struck
Sacred
Galway, Ireland

Chapel of the Vertical Board / 2022

A roadside chapel where the boards run vertically, drawing the eye and the light upward. Daylight enters only through the seams between the timber planks.

TypeChapel
Height9.4 m
BoardsVertical fir
Cultural
Porto, Portugal

Foundry Gallery / 2021

A disused foundry reborn as a gallery. New board-formed inserts are cast against the old brick, each pour deliberately mismatched to mark the passage of a working day.

Civic
Aarhus, Denmark

The Reading Bunker / 2020

A half-buried public library. Above ground, only a board-formed parapet shows; below, light wells of raw concrete carry daylight to the stacks.

Concrete remembers everything - the timber, the weather, the hand that poured it.

03 - Process

Four stages, one pour.

From the selection of a single tree to the day the formwork comes away - our method is built around the irreversibility of cast-in-place concrete.

01

Select the Timber

We choose and grade every board for grain, width and texture before a single line is drawn. The wood determines the wall.

02

Build the Formwork

The mould is a piece of carpentry in its own right - boards aligned to the millimetre, ties set on a designed grid.

03

Cast in Place

A single continuous pour, vibrated by hand. There is no correction afterward; the rehearsal is the work.

04

Strike & Reveal

The formwork is removed. The grain of the timber, now permanent in the concrete, is seen for the first time.

Build something that will outlast us.

We take on a small number of projects each year - houses, civic rooms, places of quiet. If you want raw concrete done with conviction, write to us.
