What is architectural design and planning?
Designing and building under one roof means the drawings are priced as they are drawn, so there are fewer surprises when the quote arrives. If you only need drawings and a planning application, we can do that and you are free to use any builder.
- Design options and 3D views
- Planning or lawful development certificate drawings
- Submission and liaison with the planning officer

Do you need permission for architectural design and planning in Ashford, Surrey?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
We confirm whether your project is permitted development, needs prior approval or needs a householder application, and prepare the right submission. A lawful development certificate is the best proof that permitted development work is lawful.
What can change the price or programme?
- Planning and building regulations are separate approvals; most projects need building regulations even when planning is not needed.
- Conservation areas and listed buildings need extra design care and supporting statements.
From first call to completion
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
