Extension Plan

We are a small team of architectural designers and RICS Chartered Surveyors who provide a range of services to homeowners looking to extend their properties, including planning applications, building regulations drawings, party wall surveying, and structural calculations.

Since 2015, our team has helped with residential extensions across the South East London, Kent, Surrey and Sussex.

Contact us about your home extension.

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.

Quality

We never compromise on quality. Our drawings are fully compliant and just like you’d get from an architect, only cheaper.

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.
