Homes in the South West
Homes in the South West range from coastal and rural properties in stone and slate to city terraces and modern estates, so extensions are designed to match the local materials.
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.
- Foundations, brick piers and insulated base
- Insulated roof perimeter with plastered pelmet
- Heating, electrics and decoration-ready finish
What is the guide price for an orangery in St Austell?
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.
- Heating should be part of the house system, not a plug-in heater.
What are the steps?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- 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.
