Castle Greenhouses For Sale

We have designed our exclusive Castle Greenhouses and our range of Peak Greenhouses as a direct result of your feedback. You can imagine that at our display sites we gather a large amount of positive feedback about what customers really need and want from a greenhouse and we have incorporated all of that into the design of these new exclusive ranges.

High eaves

Many greenhouses on the market can be too low – this limits working and growing height and shelf capacity. Most Castle models are now 'high eaves'– at around 5'4" this is about a foot higher than the industry standard.

No step at the door

Most aluminium greenhouses come with a 5" high metal base, unfortunately this causes a trip-hazard and impedes wheelbarrow and wheelchair access. All the Castle models now feature a unique ground level threshold which allows easy and safer access.

Good ventilation

Most greenhouses do not feature enough ventilation. This is vital for the health and vigorous growth of your plants. View our unique package deals which feature extra louvre side vents and automatic roof vent openers.

Quality staging and shelving

It's easy to overlook your staging and shelving when ordering a greenhouse. In fact, this is vital to your success as you can gain up to double the working space just by laying out your staging and shelving properly. Our experts will be pleased to help you plan this and we have a vast range of distinctive styles.

Built to last

In this 'throwaway age' it is refreshing to know that some things are still built in Britain and built to last. Most of our range is made in Britain and all models come with a 10-year Frame Guarantee. Add to this the fact that we are physically based in 33 garden centres around the UK so you can count on reliable support after your order is placed.

Safety

The safety of you and your family is always of primary concern. Note that 3mm horticultural glass is still an industry standard in many greenhouses. It is available from us for entry level greenhouses, but we recommend (and most of our customers choose) toughened safety glass. This is cut to size and then tempered so that if it breaks it shatters into thousands of small pieces, greatly reducing the chance of serious injury. All our recommended packages include toughened safety glass which is supplied in large panes rather than small overlapping panes. This removes the unsightly overlaps that are so common on some makes of greenhouse.

Castle and Peak aren't the only range of Aluminium Greenhouses for sale. We also offer Elite Greenhouses, our own GBC Package Deal greenhouses and greenhouses from the UK's leading supplier of superb quality greenhouses - Robinsons. All these ranges come with many options and styles to choose from to best suit your needs. You can choose anything from Victorian style greenhouses, slimline greenhouses, lean-to greenhouses and a range of fantastic freestanding greenhouses.
