Our experienced team specialises in designing a wide range of projects across England — including single- and double-storey extensions, garage conversions, wrap-around extensions, kitchen and rear expansions, and more. Regardless of the scale or complexity, we ensure your design is functional, stylish, and fully compliant with planning and building regulations. Explore our pricing guide for different project types to help estimate your costs.

Our Planning Permission and Building Regulations service covers all essential drawings and the complete submission process.
We provide end-to-end Planning Permission services, from pre-planning to securing approval. This includes a site visit and measured survey, preparation of existing and proposed plans (scaled at 1:100), sections if required, layout revisions, and site/location plans. We handle application submissions (excluding council fees) and act as your agent throughout. If additional documents are required beyond the basic drawings, we can source them for you at an extra cost—ensuring a smooth, stress-free process from start to finish.

We deliver comprehensive Building Regulation drawing services, including detailed cross sections, full specification drawings with construction detail callouts, and all required documentation for submission to your local Building Control. If needed, we can also provide structural calculations. Our service ensures your project meets all regulatory standards, streamlining the approval process from start to finish.
