Covering Milton Keynes
We work in Milton Keynes (MK1, MK4, MK6) and the places around it, including Bletchley, Leighton Buzzard and Buckingham.
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.
- Design to suit the house style
- Insulated roof perimeter with plastered pelmet
- Glazed roof lantern and windows or doors
How much should I budget for an orangery?
Typical ranges for orangeries. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| 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 |
What approvals does an orangery 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.
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. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.
What should I think about before starting?
- An orangery open to the house needs to meet energy rules, which limits the proportion of glazing.
- Solar-control glass in the lantern stops summer overheating.
What happens after I enquire?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Your questions answered
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.
How long does it take to build?
About 8 to 14 weeks on site.
Can you visit a house in Milton Keynes 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.
