The first drawing on every project we take on is made by hand, at 1:100, in soft pencil on a roll of tracing paper laid over the site survey. It is rarely beautiful. It is usually wrong in a dozen places. And it decides almost everything that follows, which is why we have never handed it to a computer.
Slowness is the method
A pencil line takes time to make, and that time is thinking time. On a screen a wall is a command: you click twice and it exists, perfectly straight, at whatever length the cursor happened to stop. On paper you have to decide how long it is before you start, and while your hand is moving you are already asking whether it should be there at all. The slowness filters out the easy answers.
On tracing paper the previous idea is always visible underneath the next one.
That is the other quality we value. When we lay a fresh sheet over yesterday's drawing, the old lines show through, faint and grey. We redraw what still works and leave the rest behind. After a week the roll holds a record of every decision and every abandoned option, in order. Clients like to unroll it at the end of a project. So do we.

Scale keeps you honest
Drawing by hand also fixes the scale. At 1:100 a metre is a centimetre and a pencil line is about five centimetres thick in reality. You cannot draw details you have not thought about yet, so you do not pretend to. A screen lets you zoom from the whole site to a door handle in a second, and it is easy to start polishing a handle before you know where the door goes.
Then the computer, gladly
None of this is nostalgia. Once the first drawing has settled, usually after two or three weeks, everything moves into the model and the drawing set, and we are as digital as any practice in Porto. The computer is better at coordination, at structure, at the hundred sheets a builder needs. It is just not better at the first line. That one still belongs to a hand, a pencil and a quiet morning.
