Factors Affecting Conservatory Price:

Conservatory:

  • Location: Frequently a conservatory is into a corner, with just two sides, or into a courtyard, with only one side.
  • Size: width, projection, frame height, height at house wall
  • Type: Conservatory with 75%+ glass roof, Orangery having flat roof and central lantern or Garden Room with tiled or slate roof, both the latter requiring building regulations.
  • Material: from white PVC at 45% of the cost of Oak, rising through coloured PVC, aluminium, pine, Sapele, Idigbo to the very best seasoned Oak
  • Frame type: Storm-proof sashes, standard with 70mm frames. Flush, conservation sashes with 90mm frames. Typical for Listed Properties.
  • Frame features: Do you require glazing bars, such as Georgian style squares, leaded lights or coloured glass features?
  • Doors: number and position of doors or double doors (recommended door width 700-800)
  • Window openings: number and position of openings (recommended window width 700-800) Recommended min of 2 full height openings, 4 if conservatory over 10 sq.m.
  • Frame/roof centres: Important – window sashes shouldn’t exceed 800mm, if you want the roof rafters to align with the frames.
  • Roof Design: the simpler the design, the lower the price.
  • Box Gutters: Does the design require a box gutter. If so, does it need to be structural?
  • Insulation: A rated glazing with minimum of 1.1 u value insulation recommended
  • Roof glass: solar control glass should be standard unless in the shadow of a North facing house (0.9-1.0 u value, keeps out up to 78% of unwanted heat)
  • Frame glass: clear solar control glass with 1.0 u value, should be used on South facing conservatories.
  • Roof Ventilation: warm air rises – it’s essential to fit roof vents minimum one up to 12 sq.m., two over. These can be manual, electric or automatic.
  • Planning: Depending upon the position and size, amongst other factors, such as being Listed or in a conservation area or area of outstanding natural beauty, etc. will determine whether you need to allow for Planning Costs.
