Home Extensions





House Extension Requirements in London

A house extension typically falls under permitted development, meaning it doesn't require planning permission. However, regulations for house extensions can differ between London boroughs. As leading house extension builders in London and the Greater London area, we possess in-depth knowledge of the planning process. We will inform you about any restrictions specific to your house or location right from the start, shaping the design of your house extension accordingly. We will also prepare and submit all the necessary documents and drawings to the relevant authorities on your behalf, including:

  • Obtaining planning permission
  • Securing building regulations approval
  • Establishing Party wall agreements

Specific information is required to inform the technical and practical aspects of your planned house extension's design and construction. Typically, this information is gathered through surveys to determine factors like the precise site dimensions, equipment and tool access, soil composition, the location of load-bearing walls if they're being modified, and the positions of trees and drains that might influence the design. These surveys may need to be included in any planning application.
