Working in Ammanford
We cover Ammanford and the postcode districts SA18. The same team covers Llanelli (11 miles), Carmarthen (14 miles), Pembroke Dock (41 miles), Haverfordwest (42 miles), all within easy reach.
Clydach, in West Glamorgan, is roughly 8 miles from Ammanford and also on our list. In Wales, terraced houses with rear offshoots are common in the towns, while detached houses and bungalows dominate in rural areas.
Planning and approvals in Ammanford
In Wales a glazed or orangery-style extension follows the normal single-storey limits (up to 4 m at the rear). Welsh building regulations also limit glazing and heat loss, so glass-heavy designs need calculations.
The planning position for a specific Ammanford address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. Wales has its own building regulations and approved documents; the council or a registered building control approver checks the plans, inspects the work and issues a completion certificate.
The Party Wall etc. Act 1996 applies in Wales as in England: notice must be served before work to a shared wall, building on the boundary, or excavating close to a neighbour's foundations.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).
What we take care of
- Design of piers, roof perimeter and lantern proportions
- Aluminium or timber lantern and full-height glazing
- Heating sized for the glass area
- Thermal calculations where glazing is generous
- Opening into the main house
- 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.

Common questions in Ammanford
How long does an orangery extension take to build in Ammanford?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Do you cover all of Ammanford?
Yes. We cover Ammanford and the surrounding parts of Dyfed. Site visits are free and there is no obligation.
Do I need building regulations approval in Ammanford?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Will an orangery be too hot in summer?
Not if it is designed with solar-control glass, a solid perimeter and ventilation. We size the lantern and opening vents with that in mind.
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.
