Local to Camborne
Across TR14, we can visit, measure and advise. We also work in nearby Redruth (4 miles), Falmouth (11 miles), Truro (11 miles), Penzance (12 miles).
Just over the Devon border, Plymouth is about 52 miles away. South West homes range from terraced streets in the cities to stone cottages and bungalows in the countryside, and conservation areas are common in historic centres.
What is included
- Foundations, walls and insulated perimeter roof
- Design of piers, roof perimeter and lantern proportions
- Thermal calculations where glazing is generous
- Opening into the main house
- Heating sized for the glass area
- 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.
Planning rules that apply in Camborne
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.
The planning position for a specific Camborne 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. 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).
