Buckingham questions

Can’t find what you need? Call 01491 612820.

What sizes does the Buckingham come in?

From 5.5m × 3m to 10m × 5.5m, in half-metre steps, with a price for every size in the guide above. Other dimensions are available through our bespoke service.

What is the difference between Professional and Premium?

Both are complete, installed specifications. Premium adds an engineered oak floor, painted plasterboard walls and ceilings, Thermowood cladding, an external consumer unit, dimmer switching and brushed stainless fittings, plus external spotlights, and upgraded insulation in timber-frame builds. Compare them side by side.

Can I customise my Buckingham?

Yes. Each element can be customised or tailored, from doors and skylights to the roof, cladding and interior, or the whole room can be made bespoke to order. Your designer will price anything tailored with you.

Which doors can I have?

French or bi-fold doors as standard, set by the width. Sliding doors: ask your designer. Standard: French doors 2m × 2m at 5.5–6.5m wide · bi-folds ×3 at 7–9m wide · bi-folds ×5 at 9.5–10m wide. Every Buckingham also has one fixed tall window, 0.8m × 2m.

Can it meet Building Regulations, or become an annexe?

Yes, depending on the specification. The Buckingham is built to true building standards, and our bespoke service can adapt it into an annexe.

Will I need a base?

Yes: a concrete base or ground screws. Where your ground needs it, an optional site survey (£460 inc. VAT) recommends the right one for your garden, and we quote it separately.

Do I need planning permission?

The Buckingham is designed to comply with permitted development in most cases. Sleeping or living in it needs planning permission. Planning guide
