Covering Harpenden
Harpenden sits 5 miles north of St Albans, with St Albans 5 miles to the south and Luton 5 miles to the north-west.
Homes in the East of England
Housing in the East of England ranges from post-war estates and modern developments to timber-framed and period homes in historic towns, so permitted development checks and conservation controls both feature regularly.
What is included in an orangery in Harpenden?
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.
- Design to suit the house style
- Planning or permitted development check
- Foundations, brick piers and insulated base
What is the guide price for an orangery in Harpenden?
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.
What can change the price or programme?
- Timber-look aluminium or timber frames suit period houses.
- Solar-control glass in the lantern stops summer overheating.
