The Process for Extensions and New Builds

Streamlined 3-Stage Approach

1) Planning

Start by appointing an architect to create the plans for your project. Once you’ve agreed on the designs, these plans will be submitted to the local planning authority for approval.

Permitted Development: Some works may fall under permitted development, which means no official planning permission is needed. The majority of projects will require formal approval, which can take up to 8 weeks.
Flexibility: Planning focuses on the external appearance of your property. If you’re unsure about the scope of work, it’s best to include all potential areas of change in the submission; you can always scale back later. Internal layouts are flexible and can be adjusted during the build.

Inclusions: Be sure to include any major changes to gardens and driveways in your submission as well.

2) Building Regulation Approval

Once planning permission is granted, the project parameters are set. Your architect will refine the drawings to include construction details like drainage layouts, insulation, ventilation, and critical measurements.

Engineering Collaboration: At this stage, an engineer, often coordinated by the architect, will provide details on structural elements such as steel works, foundations, and roof structures. These details will be incorporated into the drawings.

Submission for Approval: The marked-up drawings, along with the engineer’s details and calculations, will be submitted to the local authority building control or a private authority for approval. Building control acts as the structural warrantor for your project.

3) Schedule of Works / Client Specification

Some architects may offer a separate document for this stage at an additional cost, but clients can also compile it themselves. This document outlines your specific needs and preferences, including:

Plumbing: Sanitaryware, heating types, and renewables
Electrics: Lighting and power
Finishes: Tiling, flooring, joinery (doors, skirting, cabinets), and decoration
Landscaping and Glazing: Areas not shown on drawings
Areas of work not shown on drawings: For example all the windows need changing

Once these three stages are complete, we’ll have all the relevant information needed to provide an accurate and realistic price for your project, ensuring you achieve your desired outcome.
