Convert to Flat in London


At Satz Architecture & Build we have successfully designed a large number of flat conversions across London and the South-east and know how to get the best project build.

A single story extension is a great way to add more space on the ground floor whether it be a larger lounge, dining area, orangery or spare bedroom. Thanks to new regulations there are a number of options when it comes to making an application, these include: Permitted development, The Larger Home Extension Scheme and planning permission.

Our Process

  1. Property Survey – We visit your property to take accurate measurements and discuss the project.
  2. Design Stage – First we design your proposed Floor Plans for your approval and the Proposed Elevations
  3. Finalized Design – Once we have made any amendments through your comments and feedback we then send over the final design plans.
  4. Submission – We then submit the plans to your Local Authority and act as your agent during the application process.
  5. Building Regulations – Once planning is approved then Building Regulation approval will be required before building works begins.
