Building Regulations Drawings for Home Extensions

Building Regulations drawings are required whenever you intend to undertake construction work to your property, such as an extension or loft conversion. The purpose of Building Regulations drawings is to ensure that the works meet the standards set out in the Building Regulations and meet the required thermal performance, fire safety, and various other standards set out.

We can then submit your drawings to your local authority online and manage the planning process for you.

Planning Decision

The local authority will then decide your application. This process typically takes 8 to 12 weeks, after which you will receive your fomal planning decision.
