Introduction

The planning regime for flats and maisonettes differs in many important ways to that which covers houses.

Bear in mind that the permitted development rights which apply to many common projects for houses do not apply to flats. Use the links on the left to find information about several common projects specific to flats and maisonettes.

Build Aviator's estimating service can help you plan your project by providing an accurate cost of the proposed changes. Find out more1.

Once costs have been estimated, the quick quote finance calculator2 from Selina Advance can take all of the hard work out of searching and securing the funds needed for your project.
