Project Overview


Three Quarter Span


4.6m x 4.6m



The clients came to Alitex with the plan to build a structure onto the back of an existing garage. Several options were considered before deciding on a 3/4 span Traditional glasshouse. In order to be harmonious with the overall height of the garage, a relatively low pitch of the greenhouse roof was needed on this small 4.6m x 4.6m structure.

Although listed consent was not necessary as the greenhouse was not to be attached to the house, planning permission was needed to build within the grounds of the Grade 2 listed property.

As the greenhouse was almost square, it required special design input to ensure wind and snow loadings were not compromised, whilst not interfering with the overall aesthetics.

The existing garage was a rather unsightly 1960’s construction, so the client decided that the rear elevation was to be knocked down and rebuilt in a more sympathetic brick.

Our clients had an antiques business, Spencer Swaffer of Arundel in Sussex, which meant the greenhouse was destined to be the most stylish in town. They thought that a stone trough sink on brackets and copper plates would be a good addition to disguise the irrigation mist risers which were built into the gable end plinth walls.

Every single greenhouse is going to be different, specific to you. What you want is what you get with an Alitex greenhouse.
