This Mercia 6 x 3ft Wooden Victorian Growhouse is the perfect addition to the back yard of an avid gardening enthusiast who doesn’t have much space to spare.

Styrene glazed windows are fitted to allow natural light into the building, encouraging the growth of plants and vegetables. The panels used in this wooden greenhouse are made using 12mm shiplap cladding, the interlocking nature of this construction creates a solid panel that prevents weather getting in and damaging plants and tools. Because the styrene glazed windows are UV treated, there is no need to worry about the panels cracking or discolouring over time; the UV treatment also helps to protect plants inside from harmful rays.

Opening windows feature on top of this growhouse so that gardeners can regulate the temperature inside to suit the produce they are growing.

A classic pent roofline helps with water drainage, an essential feature that prolongs the life of the timber. A savvy gardener can also use this roofline to harvest the rainwater for use on their produce.

Although a coat of treatment is applied in the factory, it is recommended that a second coat is applied upon delivery. A 10-year anti rot guarantee is supplied as standard.

Rated 4 out of 5 by from Nice product, impossible warranty Product good quality but anti rot warranty says it will be invalidated if built within 60cm of a wall. Surely that is the point of a lean to greenhouse and what is shown in the merchandising pictures. If you use it as intended the warranty is useless.

Rated 4 out of 5 by from It's up He greenhouse is just what I wanted. The idea of leaving the cover on the windows made painting around the windows really easy. The only downside is that unfortunately as we were putting it together two of the planks were rather warped. One was put in place with a longer screw but the other too badly bowed. It still does it's job well. I like that the back shelf can be dropped. I have only made one side shelf permanent, the other sits very well on the fixtures. Not the easiest to put together it took my 2 sons a whole morning!

Rated 5 out of 5 by from excellent product Really happy with this greenhouse. Took our time putting together over three days. We chose to treat (varnish/paint) before we built. Clear instructions, plenty of screws. There were so many extra we chose at some points to use larger/smaller depending what was needed. The fold down shelf was a very tight fit so would recommend making sure the two side shelfs are fitted correctly. When it was delivered, on a Tuesday one of the doors was damaged. Customer service were very helpful and we had a replacement by the Friday.

Rated 4 out of 5 by from Great small greenhouse Arrived in two deliveries, one week apart, have us time to read the instructions carefully and sort out screws etc. Took us two days to put together ( two older adults) and very ply with the end result, it's big enough for my vegetables and some annuals to grow on. My only concern is the roof, I would have liked there to be an overhang as the rain runs down the front of the greenhouse, I have ended up buying two plastic panels to extend the roof.
