Why we still draw by hand before we draw on screen

Halston is a digital practice. We model every project in BIM software, deliver technical drawings in coordinated digital files, and use environmental simulation tools that would have been unimaginable to architects of a previous generation. None of this changes our conviction that the early stages of architectural design should be conducted by hand.

The reasons are not nostalgic. They are practical. Hand drawing forces decisions about proportion, scale, and material that digital modelling allows the designer to defer. Working in pencil and on paper, the designer cannot defer the question of what wall thickness is appropriate, what proportion of opening is appropriate, what scale of figure to draw alongside. Each decision is made and committed, and the resulting drawing is the trace of a sustained design judgement.

• Every project at Halston begins with hand drawing at multiple scales: site sketches at 1:500, plan studies at 1:100, detail explorations at 1:20 and 1:5
• Physical study models in card, balsa, and 3D printed plastic are produced alongside the drawings at every stage of concept design
• BIM modelling begins only when the design intent has been resolved through hand drawing and physical modelling, typically at the developed design stage

The transition to digital

The handover from analogue to digital is one of the most important moments in any project. Conducted at the wrong stage, it can lock in design decisions that should still be open. Conducted at the right stage, it allows the digital tools to do what they are designed to do: coordinate, communicate, and document a design that has already been resolved through more flexible means.

• Hand drawing remains the primary design tool through brief development, site analysis, and concept design
• Physical study models support hand drawing through massing studies, material exploration, and circulation testing
• BIM modelling takes over at developed design, when the project geometry, materiality, and structural strategy are sufficiently resolved to benefit from digital coordination

"The drawings we hand to our consultants and our clients are digital. The drawings we make for ourselves, while we are still deciding what the building wants to be, are almost always still on paper."
