Quotes (Architecture)
William Shakespeare (1564–1616) When we mean to build,We first survey the plot, then draw the model; And when we see the figure of the house, Then we must 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? (Henry IV, Part Two, I:3)
