Homes in London
Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.
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.
- Insulated roof perimeter with plastered pelmet
- Glazed roof lantern and windows or doors
- Heating, electrics and decoration-ready finish
How much should I budget for an orangery?
Indicative costs for orangeries. London and the South East usually sit towards the top of each range.
| 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?
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. 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.
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.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
