Lean To

A lean to greenhouse or orangery is a wonderful option if you have a high wall. The wall collects and stores the sun’s heat during the day and then emits this at night which helps maintain the greenhouse temperature. Our beautifully designed lean to greenhouses and orangeries usually have full length ventilation to the ridge as well as side ventilators to maximise air circulation. The size of a lean to greenhouse is governed by the height of the high wall. In general, for a width of 2.4m (8 feet) the wall will need to be at least 3.2m (10 feet 6 inches) high. If your wall isn’t high enough, then a 3/4 span (also known as an offset ridge) is a very attractive alternative.

Griffin’s glasshouses offer these gardener-friendly features:

  • The beauty of wood without the maintenance headaches.
  • Maximum ventilation so that your plants won’t dry out or suffer the effects of humidity.
  • Large covered water storage tanks so that you can store clean soft rainwater inside your greenhouse for watering your plants without shocking the roots at the height of summer.
  • Flexible shelving and benching to accommodate changes to your growing schemes.
  • Cold frames with lids especially designed not to lift off in high winds.
  • Doors designed to fit a wheelbarrow.


Every glasshouse is unique and so are your needs as a gardener when it comes to creating the perfect environment for your plants and accessorising your glasshouse in style. Whatever your chosen style and planting plans, we can manufacture or source a full range of accessories on your behalf or put you in touch with other recommended suppliers. From propagators to potting benches and floor grates to grow lights, we will ensure that your glasshouse is fully equipped with everything you need and share the benefit of our advice and experience to help you choose (and spend) wisely.
