The studio

Five people, one room,
above an old lace
warehouse.

We keep the studio small on purpose. The people you meet at the first sketch are the same ones on site at the end, and nothing gets lost in a hand-off. Around eight jobs a year, all within an hour of Nottingham.

Architect

Technical design and detail. If a drawing has a full-size section on it, he drew it, and the builder has his number.

Kitchens, bathrooms, joinery and finishes. Keeps the sample library, and the joiners honest.

Models, daylight studies and the drone. Learning the planning system the hard way, with us.

How we work

We start on site, draw it small before we draw it big, and build it once.

Every job begins with a walk round the plot, however small. Then card models and rough plans, because it's cheaper to throw away a weak idea on paper than halfway through a build. Then a set of drawings a builder can price without guessing, and a visit every week until it's done.

The tools

Card, pencil, and a computer when it earns its place.

We use the software everyone uses. The things below are what we think make the difference, and most of them are older than the studio.

A model at 1:100 takes a day and answers the questions a rendering hides: where the shadows fall, whether the roof reads as one thing or three.

A daylight model

We run every plan through the sun for the whole year before planning goes in. It's how Bridleway's kitchen moved before it was built.

A 3D model you can walk through

On a laptop in the studio, not a headset. Useful for stairs and kitchens, where a plan never tells you how a space feels.

A proper survey kit

A laser scanner for old buildings, a tape and a level for everything else. The measured survey is the one thing we never outsource.

Builders and engineers

The people we keep going back to.

We don't have a builder. We have about nine, spread across the three counties, and we tender every job to three of them. Some have done six jobs with us; one has done fourteen. They price keenly because they know the drawings won't change halfway through, and they know we'll be on site every week.

The same goes for the structural engineers, the quantity surveyor and the two joinery workshops. You're free to bring your own people. If we think they're not right for the job, we'll say so once, in private, and then it's your call.

How a job runs, stage by stage

Come and see the room.

First meetings usually happen at the site, but you're welcome in the studio. Top floor, through the arch off Weekday Yard, up the stairs that need a handrail we keep meaning to draw.
