Covering Hampshire
Our coverage across Hampshire includes Southampton, Portsmouth, Basingstoke and Gosport.
Homes in the South East
Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.
What is included in architectural design and planning in Hampshire?
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
- Submission and liaison with the planning officer
- Building regulations drawings and specification
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 |
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.
What should Hampshire 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
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
