Architectural Sketching on Location: How a Building Becomes a Drawing

The first mark on the page is never architecture. It is a horizon line set at the height of your own eye, and one or two vanishing points placed by judgement rather than instrument. Everything that follows hangs from that line. Get it wrong and no amount of careful window drawing will rescue the sheet.

The second set of marks is proportional: total height against total width, then the position of the largest openings. At this stage the sheet looks like a diagram, and it should. A drawing that begins as a diagram can become atmospheric later; a drawing that begins as atmosphere can never become accurate.

Architectural training teaches you to hide your workings. Drawing on location teaches the opposite. Those faint pencil lines running past the edges of a tower are the record of how the building was understood, and erasing them removes the most human part of the sheet.

In the finished prints from the archive — the Abbaye aux Dames study in particular — the construction lines are deliberately left in. They tell the viewer that someone stood there, looked, and worked it out.

Ink handles the things that will not change: the structural edges, the depth of a reveal, the shadow line under a cornice. Two pens are usually enough — a fine technical nib for edges and a brush pen for weight.

Wash handles everything that will change by lunchtime. Sky goes down wet-into-wet and fast. Stone is dry-brushed so the paper's tooth carries the texture. The whole wash stage should take a fraction of the time the line work took; hesitation is what turns watercolour muddy.

The rule across the archive is that a location drawing is finished on location. Studio corrections tidy a sheet but drain it. If the light has moved too far, the drawing is done — the next one can be better.

Practically, this means working small enough to finish: a sketchbook page rather than a board. Scale can be recovered later in printing, and the fine art prints are produced at sizes where the original pencil work becomes visible again.

Choose a building with strong repetition — an arcade, a bell tower, a row of identical windows. Repetition is forgiving: once you have established the rhythm, the eye accepts small inaccuracies within it.

Then draw the same building three times over three days. The third drawing is always the one worth keeping, and it is the reason the archive contains more sheets of a handful of places than single sheets of many.
