Notes from the studio on planning, approvals, fit-out and how projects are procured, written from our own work in London.
Practical guides for clients planning a building, interior or fit-out project.
Commercial

Planning
Planning permission and building regulations approval are separate systems that ask different questions. Many projects need both, and having one does not mean you have the other.
Commercial
CAT A and CAT B are the standard terms for the two stages of an office fit-out. Knowing where one ends and the other begins helps when you are comparing buildings, leases and quotes.

Planning
