Covering Cornwall
Our architectural design and planning service in Cornwall covers Redruth, Falmouth, St Austell and Truro and more.
Because Cornwall covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.
Homes in the South West
The South West mixes stone and render cottages, Victorian terraces in the larger towns and modern estates, and many historic centres are conservation areas where materials and roof shapes are closely controlled.
What goes into architectural design and planning?
Architectural design and planning covers everything before building starts: a measured survey of the house, design options, planning or permitted development drawings, the application itself, building regulations drawings and structural calculations. We offer it on its own or as part of a design-and-build project.
- Design options and 3D views
- Submission and liaison with the planning officer
- Structural engineer’s calculations
What will architectural design and planning cost?
Typical ranges for architectural design and planning. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| Architectural design and planning | Guide price incl. VAT |
|---|---|
| Measured survey and existing drawings | £500 to £1,200 |
| Planning drawings and application | £1,200 to £3,000 |
| Building regulations drawings and specification | £1,000 to £2,500 |
| Structural calculations | £500 to £2,000 |
What approvals does architectural design and planning need in England?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
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 should Cornwall homeowners check first?
- 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.
From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- 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
Can I use your drawings with another builder?
Yes. If you buy drawings on their own, they are yours to use.
Do I need a structural engineer?
For steels, new openings, lofts and extensions, yes. We arrange the calculations.
Do you work in Cornwall?
Yes. Cornwall is within our coverage for architectural design and planning, along with nearby Redruth and Falmouth.
