The cost of a conservatory can be from as little as £5,000 for a small and basic design, to well over £100,000 for a grand hand-crafted orangery.
How much does a conservatory cost?
Conservatories vary significantly in their style, dimensions and specification and the key factor which will determine the cost of your conservatory is the type of ‘conservatory’ you decide upon.
The average cost of building a conservatory in the UK is £9,000 for a uPVC conservatory comprising of Low-E glazing, a lean-to roof and measuring 16 square metres in ground floor area. An equivalent conservatory with a gable or hipped Edwardian roof will cost in the region of £11,000, but will create a grander feel to your conservatory.
In terms of roof materials, a polycarbonate roof is a lower cost alternative to glass and although may not be as visually appealing, it does have some benefits over glass (namely increased sound and heat insulation).
Sun room, sun lounge or garden room
Sun rooms generally cost more than fully glazed conservatories but less than solid extensions. The average cost of building a sun room in the UK is in the region of £17,000 for a room measuring 16 square metres in ground floor area.
Orangeries are traditionally constructed from solid walls with hardwood fenestration, doors and roof lights. Orangeries can vary substantially in their costs based upon the level of finishing detail you require. As a very general rule, an orangery measuring 25 square metres in ground floor area and fitted with hardwood fenestration and doors would cost upwards of £50,000, whereas an equivalent orangery fitted with uPVC fenestration and doors would cost in the region of £40,000.
