The cost of the construction

When we mean to build

We first survey the plot, then draw the model;

And when we see the figure of the house,

Then must we rate the cost of the erection;

Which if we find outweighs ability,

What do we then but draw anew the model

In fewer offices, or at last desist

To build at all.

Enrique IV, II parte, Acto 1º

William Shakespeare
