Homes in the South East
The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.
What is an orangery?
An orangery is a single-storey extension with brick piers or walls, large windows and a glazed lantern set into a solid, insulated roof. It sits between a conservatory and a full extension: lighter than an extension, warmer and more solid than a conservatory.
- Planning or permitted development check
- Foundations, brick piers and insulated base
- Heating, electrics and decoration-ready finish
What will an orangery cost?
Use these ranges to budget for orangeries; the survey turns them into a fixed price for the agreed specification.
| Orangeries | Guide price incl. VAT |
|---|---|
| Standard specification | £3,000 to £3,500 per m² |
| Good specification | £3,500 to £4,100 per m² |
| High specification | £4,100 to £4,800 per m² |
Planning and building rules in Ashford, Surrey
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.
In England a single-storey rear extension can often go ahead under permitted development: up to 3 m deep on an attached house or 4 m on a detached one, no higher than 4 m, with eaves no higher than 3 m within 2 m of a boundary.
What can affect an orangery?
- An orangery open to the house needs to meet energy rules, which limits the proportion of glazing.
- Timber-look aluminium or timber frames suit period houses.
What are the steps?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- 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.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
What people ask before starting
What is the difference between an orangery and a conservatory?
An orangery has a mostly solid, insulated roof with a glazed lantern and brick piers, so it behaves like a room of the house. A conservatory is mostly glass.
Does an orangery need building regulations?
Usually yes, because it is built as part of the house rather than as a separated conservatory.
Can you visit a house in Ashford, Surrey 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.
