Covering Horley
Our coverage around Horley (RH6) also includes Crawley (4 miles to the south) and Redhill.
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 is included in an orangery in Horley?
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
- Insulated roof perimeter with plastered pelmet
- Heating, electrics and decoration-ready finish

Planning and building rules in Horley
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 should Horley homeowners check first?
- 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.
How does the project run?
- 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.
Questions about an orangery in Horley
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.
