Common questionsconversions

Quick answers

Does office to residential still work under Class MA?

In many cases yes, through prior approval rather than full planning, subject to conditions on size, use history and location. We check your specific unit before you commit.

What do HMO layouts have to comply with?

Room sizes, fire escape, compartmentation and amenity standards, which vary by council and licensing scheme. We draw to the standard your authority applies.

How quickly can you turn drawings around?

We aim to complete your drawings within 10 working days unless we agree otherwise, so the application is not what holds up the deal.

Why use Exp|Arc as a landlord?

One fixed price per scheme, drawings that work for both planning and building control, and a 100% refund if any application we submit is refused.
