Stage 1 Design & Planning


This step is where we work out the cost of surveying, measuring, and drawing your existing property. We need to do this so we know what we're starting with for your new plans.

Choose Your Desired Extension

Stage 2 Planning Application Fees


To build your extension, we need to get your plans approved by the local authority. That's covered in this step.

This section includes £225 for our assistance with your planning submission.

Stage 3 Building Control Estimates


Building control is the technical part of the pre-build phase. Structural engineers will run all of the structural calculations, to make sure your new extension is safe and sturdy. We'll then get these plans approved with Building Control.
