This is an "Yvonne" greenhouse which I've redesigned again - reducing the pane width, adding extra uprights on the gable ends, shaping the glass edges into the guttering, altering the glass rebates to improve how the glass is retained and making a "cleaner" fitting with reduced installation time. One of the benefits of being a sole worker is I can keep improving the designs without having to revise training manuals or go to committee meetings to get approval.
This greenhouse is made from tanalised pine with 3 coats of German paint (Profilan Impra Opac) and Pilkington's toughened glass. The next installation in a couple of weeks with be the same greenhouse but using Accoya wood instead (carrying a 50 year guarantee) and the paint will be mixed to Lichen (Farrow & Ball colour range) rather than Green Smoke as above. The paint can be mixed to any shade you find (any paint chart or RAL number) although most people like the Farrow & Ball range.
There are 4 auto-opening windows in the roof and 2 manual ones along the sides to give ample, flexible ventilation options. All the glass is held in 15mm deep rebates and sealed with exterior grade silcone as a water bar along the joints which has a life expectancy of 25 years.
Of course all the shelving, guttering, walls are included - even the potting tray, coat hook and touch up pot of paint should you need it (the 3 coatings of paint should give 10 years service before touch-up is required).
Next week I'm laying a concrete slab for a large greenhouse around Snowden (south of Caernarfon) before returning to North Wales to fit the top on another "Yvonne" type greenhouse.
