- PlanningSame limits as single-storey rear; glazing checked for building regs
- Build time10–16 weeks on site
- Postcode districtsPR8, PR9
Included in a typical project
- Foundations, walls and insulated perimeter roof
- Thermal calculations where glazing is generous
- Heating sized for the glass area
- Opening into the main house
- Aluminium or timber lantern and full-height glazing
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.
Extensions in and around Southport
Site visits are available across Southport (PR8, PR9). Neighbouring towns we cover include Formby (7 miles), Maghull (9 miles), Litherland (12 miles), Kirkby (12 miles).

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.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
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).
Our process, step by step
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
First, a site visit: we look at the house, garden, access and drains and listen to what you need.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
With the design and specification agreed, you get a fixed written price and a start date.
Build and sign-off
Work is carried out to the agreed programme, inspected by building control and signed off at the end.
Common questions in Southport
Will my neighbours in Southport be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Do you cover all of Southport?
Yes. We cover Southport and the surrounding parts of Merseyside. Site visits are free and there is no obligation.
Do I need building regulations approval in Southport?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How much does an orangery cost?
Our guide range is about £2,280 to £4,280 per m² including VAT, so a 16 m² standard-spec orangery is typically £42,500 to £53,500 in Southport.
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.
