Extension design — Architect
Describe the space you need and how it should connect to existing rooms, garden and access. Supply plans, site information and known drainage or structural issues so the designer can assess options rather than pricing solely from a desired floor area.

What is normally included
- Extension feasibility and layout options
- Design of new-to-existing connections
- Agreed application or technical-stage drawings
What is not included
- Guaranteed consent for additional floor area
- Construction and structural design automatically included
Typical tasks
- Develop the accommodation brief
- Review site and existing-building constraints

What to include in your brief
- Existing plans and site dimensions
- Desired rooms and relationships
- Access and garden priorities
- Known drains or structural issues
- Budget and phasing expectations
Choosing the right professional
Compare how designers approach the junction with the existing building, daylight and everyday use. Ask which surveys and specialist designs are included and whether the appointment ends at an application or continues into technical coordination.
Important considerations
- Existing drainage and foundations can constrain the layout
- A concept budget can change after surveys and design development
