How can we help?

We can help with designs and layouts of our standard structures, all part of our service to you. We can also provide you with drawings and base plans on your behalf, for you to submit to your clients, and can even help with the installation should you wish.


Every single one of our structures are made with high quality clear and better grade Western Red Cedar that’s PEFC certified. This means we’re responsible for every piece of timber used. This, and the care of quality craftsmanship is the reason we are the only greenhouse manufacturers endorsed by the RHS.

RHS Portico

Perhaps the most sought after model in our RHS collection, the 'Portico', is without question a most visually pleasing structure.


It boasts a central porch entrance to the greenhouse, maintaining the narrow glass panes, steep roof pitch and hand turned finials.


Starting at a rather modest 11ft 8in in width, the 'Portico' and 'Grand Portico' collection of structures can increase in length. The 'Grand Portico' comes with double doors.

Classic Ten

Whatever the size of your garden there’s a Gabriel Ash Classic greenhouse that will suit your needs. Available in a variety of widths, 6ft, 8ft, 10ft and 12ft. The length increases in multiples of panels to perfectly fit your garden design.


The Classic collection has long been our customer’s favourite model of greenhouse, both amateur and professional alike.


Made using only the finest Western Red Cedar and supplemented with aluminium in all the key areas, our Classic structures are designed to be just that - classic.

Classic Grow & Store

Where space is at a premium, why not combine growing and storage with The Classic 'Grow & Store'.


With half a greenhouse and half a shed, this structure is perfect for those not able to accommodate both. Access from the greenhouse to the shed is through the space saving sliding door in the vertical wall dividing the two sections.


Whilst the standard 'Grow & Store' is approximately 9ft 4in in width, as with all the models in the Gabriel Ash collection of greenhouses, the structure can be extended.

Classic Six

The smallest of our Classic freestanding range, the Classic 'Six' Western Red Cedar greenhouse measures at six foot by eight foot length as standard, however as with all of our structures, can be extended to whatever length is necessary.

Our greenhouses are designed to easily swap out a glass pane for a cedar board or louvre vent.

​​​​​​​Our Classic and RHS range also comes with our unique full ridge automatic ventilation as well as stainless steel and solid brass fixture and fittings as standard.
