Covering Weymouth
Alongside Weymouth, we also cover Dorchester, Bridport (15 miles to the north-west) and Poole.
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 is 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.
- Planning or lawful development certificate drawings
- Building regulations drawings and specification
- Structural engineer’s calculations
How much should I budget for architectural design and planning?
What architectural design and planning typically cost. These are guide ranges; the written quote for your house replaces them.
| 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 |
Do you need permission for architectural design and planning in Weymouth?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 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 Weymouth homeowners check first?
- 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.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
