Crown Pavilions vs Green Retreats
Green Retreats' A1 (about 5.04m x 3.23m) is listed at £26,065, close to Crown's Heritage 5m x 3m at £26,650 RRP. The A1 uses steel-sheet panels with 75mm foam walls and argon double glazing, and its electrics are an optional extra. Every Crown garden room includes triple glazing, dark grey aluminium doors, smart air conditioning and a full electrical package. Green Retreats gives a 12-year guarantee on the A1, longer than Crown's 10 years. With both, the base is extra: Crown quotes it after a site survey.
