Welcome to Extension Plan

We are your one-stop shop for architectural solutions for home extensions and conversions, including extension Planning Applications, Building Regulations, Structural Calculations, and Party Wall Surveying services.

Fixed Price

We offer a fixed price on all our planning & building regulation drawings, so you now what you’ll pay.

Quick Turnaround

We turn our drawing around within 10 working days from the date we receive the property measurements.

Affordable

We believe that simple home extension drawings shouldn’t break the bank and, therefore, offer highly competitive pricing.

Measure

After the initial consultation, the first thing we need is the measurements of your property. This allows us to prepare accurate existing drawings. These can be obtained in one of two ways:

  1. Self Measure – You provide us with your property’s existing measurements using our simple to follow home measurement guide. Available UK-wide.
  2. Measured Survey – We arrange for one of our experienced surveyors to visit your property and undertake a measured survey. This service is available in London, Kent, Essex, Sussex, and Surrey.
