Towns in Forth Valley
Included in a typical project
- Thermal calculations where glazing is generous
- Opening into the main house
- Design of piers, roof perimeter and lantern proportions
- Foundations, walls and insulated perimeter roof
- 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 Forth Valley
In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted.
Homes in conservation areas, national scenic areas and listed buildings have tighter rules, so we always check the property's status and planning history before design starts.
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Applications are decided by your council as planning authority.

Questions people ask about orangery extensions
Do you cover all of Forth Valley?
Yes, across the whole of Forth Valley. Site visits are free and there is no obligation.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Forth Valley, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will my neighbours in Forth Valley be involved?
If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.
How much does an orangery cost?
Our guide range is about £2,350 to £4,410 per m² including VAT, so a 16 m² standard-spec orangery is typically £43,500 to £55,000 in Forth Valley.
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.
