Understanding what affects the cost of an orangery in the UK helps homeowners plan a realistic budget for their dream extension. Farrow Jones specialises in bespoke orangery extensions that balance premium features with value, ensuring your investment transforms your home without surprises.

Size and Footprint of Your Orangery Extension

The single biggest factor in orangery cost is size. A compact 15-20m² orangery extension suits small family dining spaces, while larger 40m²+ open-plan kitchen orangeries naturally command higher investment. Complex shapes – like L-shaped or multi-angle designs – add to orangery extension cost due to extra materials and engineering.

Glazing, Roof Lantern and Frame Choices

High-performance glazing, signature orangery roof lanterns and frame materials significantly influence what is an orangery pricing. Triple-glazed panels with low-E coatings keep UK orangeries comfortable year-round but cost more than basic double glazing. Slim aluminium or timber frames for modern orangery extensions also elevate the total compared to standard uPVC.

Site Conditions and Build Complexity

Your property’s location affects Orangery Extension Cost. Challenging ground requiring deep foundations, limited access for machinery, or complex drainage rerouting all increase labour and time. Properties in London (the orangery London style) or Stirling (the orangery Stirling heritage look) often face stricter planning, adding professional fees.

Interior Specification and Finishes

Once the structure is complete, interior choices drive up cost of orangery builds. Underfloor heating, bespoke kitchen integration, premium porcelain flooring, and designer lighting turn a basic orangery into a luxury extension orangery. Open-plan orangeries and extensions blending with existing kitchens require structural steelwork, further impacting budget.

Planning and Professional Fees

While many orangeries qualify for permitted development, planning applications, building regs certification and structural calculations add to orangery cost. Bespoke designs for conservation areas or listed buildings (common for orangeries UK) involve architects and heritage consultants.
