Orangery Design Check List

orangery-design-check-list
The following are all important issues in the design & construction of orangeries and should all be added to your orangery design check list.

  • Location: Frequently an orangery is into a corner, with just two sides, or into a courtyard, with only one side.
  • Size: consider the width, projection, frame height, height at house wall. You are best assessing size within an eisting room in the house. The orangery will always look larger because of the glass and roof lantern.
  • Possible Types: Conservatory with 75%+ glass roof, Orangery having flat roof and central lantern or Garden Room with tiled or slate roof, both the latter usually require building regulations.
  • Material: from Pine, Sapele, Idigbo to the very best seasoned Oak.
  • Frame type: Storm-proof sashes, standard with 70mm frames. Flush Conservation sashes with 90mm frames, usually required 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). Too many doors can make furniture layout a problem.
  • Bi-fold Doors: If you require multi-fold doors your orangery is likely to require some structural steel?
  • Window openings: number and position of openings (recommended window width 700-800) Recommended min of 4 full height openings, 6 if orangery over 20 sq.m.
  • Frame/roof centres: Important – window sashes shouldn’t exceed 900mm
  • Roof Design: the simpler the design, the lower the price. Consideration needs to be given to what exists above.
  • Insulation: glazing with minimum of 1.1 u value 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, is recommended for South facing orangeriy frames.
  • Roof Ventilation: warm air rises – it’s essential to fit roof vents. A minimum one up to 16 sq.m. two if larger. These can be manual, electric or automatic.
  • Environmental & Green Credentials: All the oak used for our orangeries is FSC certificated and comes from sustainable forest sources.
  • 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.
  • Building Regulations: Almost all orangeries require certification by your Local Authority Building Control and the cost of this should be allowed for, including the cost of structural engineer’s calculations, as the roof lantern is likely to be over 800kg (3/4 of a ton) and will require structural beams.
