Covering Maidenhead
Maidenhead is about 12 miles north-east of Reading. We also cover Slough (5 miles to the east), Windsor and Beaconsfield.
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?
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
What will architectural design and planning cost?

Planning and building rules in Maidenhead
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 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.
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.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Architectural design and planning: common questions
How much do extension plans cost?
Typically £3,000 to £7,000 including VAT from measured survey to building regulations drawings, plus council fees.
What is a lawful development certificate?
A certificate from the council confirming that work is permitted development, which is useful when you sell.
Can you visit a house in Maidenhead to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
