Western Red Cedar

Building a greenhouse using Western Red Cedar can be an excellent choice due to the wood's natural resistance to decay, which makes it well-suited for outdoor structures like greenhouses. Cedar is also known for its appealing aroma and aesthetic qualities.

Mortise & Tenon Joints

Mortise and tenon joints are a traditional woodworking joint used to connect two pieces of wood at a right angle, creating a strong and durable connection. ​​​​​​​


Precision. Dedication & Skills. All are integral to the unique craftsmanship evident in each and every Gabriel Ash greenhouse and Coldframes.

Autovents

They require no electricity to operate relying simply on the contraction and expansion of wax to open and close the greenhouse vents. The warmth of the greenhouse interior causes the wax to expand and push the vent open. Similarly, as the greenhouse cools the wax contracts and vents close.

Downpipes & Gutters

The roof pitch is 30 degrees to ensure an optimal influx of light for growing on the North European latitudes.

Toughened Safety Glass

Toughened glass in long panes and glazing capping for fitting the glass gives a beautiful look without the traditional glass overlaps and glass clips.

Many Sizes of Structures

Greenhouse growing is a hobby and a way of life whether you grow for eating or to enjoy the scent of beautiful roses. Greenhouse life is for everyone, with a garden – large or small, there is a Gabriel Ash greenhouse to suit your needs. ​​​​​​​
