Alton Evolution greenhouses

Since 1921 Alton greenhouses have been famous amongst gardeners as the leading Cedar greenhouse on the market. Well known for the best quality Canadian red Cedar which gives the Alton greenhouses a long life, and a strong and stable frame.

The iconic sloping sided Amateur greenhouse has led the market for decades and at the time of its introduction in the 50s it was at the cutting edge of greenhouse design. Now, the Alton design team have been pooling their vast knowledge and experience, along with years of feedback from our customers in order to create a Cedar greenhouse fit for the 21st Century. We're calling it the Alton Evolution range...

Designed and manufactured in the UK

Your Alton Evolution model is crafted in our own workshop in Staffordshire. Every piece of Cedar is machined in-house in our fully equipped workshop. Some of these machines have been reliably making Alton greenhouses for over 40 years. Other, more modern additions use CNC technology to give highly accurate results. Advances in machining and joinery technology have enabled for the first time a flat- packed greenhouse which actually takes no longer to assemble than the old system of awkward to handle fully glazed panels.

Alton Evolution Victorian Greenhouses

With their elegant tall windows and steep 45° pitched roofs, the Alton Victorian collection of timber greenhouses recalls a time when this country fell in love with gardening under glass. With uncompromising attention to detail and using the finest materials, our Victorian greenhouses are both beautiful and functional. The Alton Victorian is the orginal cedar Victorian greenhouse, the finest money can buy.

Alton Evolution Victorian greenhouses look fantastic in any garden and are available in glass to ground, dwarf wall and partly boarded options in a host of sizes. For full details of our alton range click here to request a brochure, or click here to visit your local Agent.

Do I need to paint or treat my greenhouse?

Your Alton Evolution is made from 100% Western Red Cedar. This kind of Cedar is absolutely perfect for greenhouses as, although it readily absorbs moisture - even to the point of looking soaking wet, it also readily gives it up and dries quickly - yet never warps or moves - this makes it ideal for the conditions in a greenhouse. Add to this the fact that it is soaked full of naturally occurring preservative oils which make it virtually immune to rot. What's more, the pungent aroma that we find so pleasant is also a deterrent to may insects and pests.

Your Alton Evolution greenhouse will be supplied in completely natural cedar which will be factory treated in a clear wood preservative. There is no need for us to ruin this natural look, which highlights the broad variation of colours in the different pieces of the Cedar, by treating it with any artificial colour. The greenhouse will last a very long time - (customers often tell us about their 30 year old Alton greenhouse at shows) you don't need to retreat it for it to last - it will simply mellow in time to a silvery grey colour, which the Moss colour of the metal parts complements perfectly.

Of course if you wish to stain your greenhouse a certain colour, or if you wish to prevent the natural ageing effect that occurs in the first year or two as water soaks in and out of the Cedar wood - lifting the darker natural oils to the surface of the Cedar - then you can of course apply a coloured wood preservative if you wish - the fact that it is in a convenient flat pack format means that this is easy for you to do before you assemble it or before your fitter comes.

The treatment that we use to factory treat your Alton Evolution greenhouse is Barrettine Clear wood preservative, whilst not necessary from a rot prevention point of view, this does help the wood to age evenly to the attractive silvery colour which is distinctive to Cedar and reduces the prevalence of stains that can develop from the water soaking in and out of untreated wood.

The only maintenance that we really recommend is that you clean your greenhouse every year, and you'll no doubt do this anyway - to keep your glass nice and clean. Cleaning any dirt or even algae off once a year in Jan/Feb time will help your greenhouse last years and get you ready for the growing season.

Your greenhouse frame is guaranteed for 10 years against rot - you never have to treat the greenhouse for this - just leave it as it is and clean it once a year.

Medal winning display of greenhouses honoured at Malvern show

The Alton Victorian greenhouse complete with matching cold frames formed the centrepiece of the Greenhouse People display stand at the Malvern show this Autumn. It must have caught the eye of the judges as they presented the stand with a silver-gilt medal, the highest award that we have ever won and one that rarely graces the world of greenhouses!

The display consisted of nine greenhouses including Alton models as well as Robinsons, Simplicity and Hercules greenhouses and the judges particularly liked the autumnal colour scheme of the planting in the specially made matching Cedar planters.

A stand at a trade show is quite a logistical operation with greenhouses; there is literally nothing for it other than to just assemble some greenhouses which involves a lot of work. In fact before that even starts, we have to lay a special wooden floor to give a nice level surface and an attractive backdrop to the show. This year’s show took fifteen working days to set up and involved 2 trucks, 4 vans, 15 bacon sandwiches and a fork lift!
