Gabriel Ash RHS Portico rangeEvery greenhouse from Gabriel Ash is made with toughened safety glass and 100% Western Red Cedar that is PEFC certified – this means they are responsible for every piece of timber used.

This, along with the high-quality craftsmanship and care that goes into building each greenhouse is why Gabriel Ash is the only timber greenhouse manufacturer the RHS endorses.  

For the enthusiastic amateur or semi-professional grower with a larger gardens, size is no object. Gabriel Ash greenhouses expand on a simple modular basis and are built to order to meet your needs.

The RHS Collection includes freestanding greenhouses, vinehouses and potting sheds in a range of sizes and many of the greenhouse models can be built on low walls, as were traditional Victorian greenhouses. All the greenhouse structures in the collection are available with the option of integral cold frames.
