Straightforward architectural packages

Most Architects in London won’t hit you with their final bill until the whole job is complete… which nearly always means a costly surprise. But not so at Architecture 100.

Instead, we give you one single, straightforward 100% fixed price from the outset – and we guarantee it’ll be more affordable than a traditional architect. So what’s the catch then? There isn’t one. We want to make buying a quality architectural package as simple and as transparent as buying a pint of milk. We have a package suitable for every scenario – whether you’re ready to dive right in and get going, or whether you just want to dip your toes in and see if potential project is feasible for your home.
