What you can estimate yourself

What you know

Floor area

The simplest figure, and the one that says most.

Number of storeys

It matters not for the multiplier but because the number of storeys determines the structure: the loading on the ground-floor walls and the bracing question follow from it.

The main spans

The difference between a six-metre and a twelve-metre span is not a factor of two but more. Long-span solutions.

The ratio of bespoke to repeating

The most important one, and the one fewest people think of. Twenty identical rooms and twenty different rooms are a huge difference in design work — the floor area is the same.

What we see

The complexity. How much structural work a given form takes, where the transfer members will be, how many connections there are, and where the services will clash with the structure.

That is what we can tell from a floor plan at a glance and what you cannot estimate — not because you do not understand it, but because it takes those few hundred completed buildings.

In practice

Describe the floor area, the number of storeys, the spans and the degree of repetition in your first message, and we can give an order of magnitude at the first conversation.

The point

Four figures are enough: floor area, storeys, span, repetition. From those we give an order of magnitude — we look at the rest.
