Covering Windsor
Windsor sits 16 miles east of Reading, with Slough 2 miles to the north and Egham 4 miles to the south-east.
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 goes into an orangery?
We build orangeries on proper foundations with insulated walls and roof perimeter, so they can be used all year as a dining room, sitting room or kitchen extension. The lantern size and the frame finish are chosen to suit the age and style of the house.
- Design to suit the house style
- Insulated roof perimeter with plastered pelmet
- Heating, electrics and decoration-ready finish
How much does an orangery cost in Windsor?
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 |
Do you need permission for an orangery in Windsor?
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?
- Timber-look aluminium or timber frames suit period houses.
- Heating should be part of the house system, not a plug-in heater.
What happens after I enquire?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- 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.
