Local to Hampton
Across TW11, TW12, we can visit, measure and advise. We also work in nearby Hanworth (2 miles), Feltham (3 miles), Surbiton (3 miles), Hounslow (4 miles).
West Molesey, in Surrey, is roughly 1 mile from Hampton and also on our list. Across London, terraced houses with narrow side returns and tight access are the norm, which shapes everything from party wall notices to how materials reach the back garden.
What is included
- Design of piers, roof perimeter and lantern proportions
- Opening into the main house
- Heating sized for the glass area
- Aluminium or timber lantern and full-height glazing
- Foundations, walls and insulated perimeter roof
The lantern-to-roof ratio sets the character. A wider solid perimeter gives a calmer, more room-like space and hides downlights and speakers; a bigger lantern feels brighter but needs more care against summer heat.
Will the council need to approve it?
In England a glazed or orangery-style extension follows the same size limits as any single-storey rear extension: 3 m or 4 m without an application, or up to 6 m and 8 m through prior approval. Building regulations limit glazing to about a quarter of the new floor area plus the openings it replaces, unless whole-house calculations show the design still performs.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).

Common questions in Hampton
Do you cover all of Hampton?
Yes. We cover Hampton and the surrounding parts of Greater London. Site visits are free and there is no obligation.
How long does an orangery extension take to build in Hampton?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Do I need building regulations approval in Hampton?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Does an orangery need planning permission?
It follows the same size limits as other single-storey extensions. In England many fit within permitted development or prior approval; others need an application.
What is the difference between an orangery and a conservatory?
An orangery has a solid roof perimeter with a central lantern and more solid wall, so it is warmer and more like a room. A conservatory is mostly glass. Building regulations treat a heated orangery joined to the house as an extension.
