Covering Horsham
We work in Horsham (RH12) and the places around it, including Crawley, Horley and Haywards Heath.
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 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
- Glazed roof lantern and windows or doors
How much does an orangery cost in Horsham?
Guide prices for orangeries, including VAT where it applies. Your fixed price is confirmed in writing after the survey.
| Orangeries | Guide price incl. VAT |
|---|---|
| Standard specification | £3,000 to £3,500 per m² |
| Good specification | £3,500 to £4,100 per m² |

How is an orangery approved in Horsham?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it 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. Deeper extensions, up to 6 m or 8 m, need prior approval from the council first.
What can change the price or programme?
- 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.
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.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Orangeries: common questions
Does an orangery need building regulations?
Usually yes, because it is built as part of the house rather than as a separated conservatory.
Can it be used in winter?
Yes. It is insulated and heated like any other room.
Can you visit a house in Horsham 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.
