Covering Tonbridge
Tonbridge sits 12 miles south-west of Maidstone, with Tunbridge Wells 4 miles to the south and Sevenoaks 6 miles to the north-west.
Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
What do you get with 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.
- Measured survey of the existing house
- Design options and 3D views
- Structural engineer’s calculations

What approvals does architectural design and planning need in England?
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 affect architectural design and planning?
- Planning and building regulations are separate approvals; most projects need building regulations even when planning is not needed.
- Pre-application advice from the council can help on sensitive sites.
What are the steps?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- 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.
What people ask before starting
