Covering Harrow
Our coverage around Harrow (HA2) also includes Brent, Wembley and Northolt.
Homes in London
London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.
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.
- Planning or permitted development check
- Insulated roof perimeter with plastered pelmet
- Glazed roof lantern and windows or doors
What is the guide price for an orangery in Harrow?
What orangeries typically cost. These are guide ranges; the written quote for your house replaces them.
| 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 |
How is an orangery approved in Harrow?
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.
What can affect an orangery?
- An orangery open to the house needs to meet energy rules, which limits the proportion of glazing.
- Timber-look aluminium or timber frames suit period houses.
