Description

Alton Victorian Westminster – Half Boarded – 10’9″ Wide

Heritage cedar craftsmanship with the warmth, privacy and protection of a traditional boarded base

The Alton Victorian Westminster Half Boarded greenhouse is a masterclass in classic English design. Combining Western Red Cedar with elegant Victorian proportions and a solid boarded lower section, it delivers a beautifully sheltered growing environment with a timeless, architectural presence in the garden.

The half‑boarded base adds insulation, reduces draughts and provides a sense of enclosure, while the upper section of 3mm toughened safety glass floods the interior with natural light. It’s a greenhouse that feels warm, calm and wonderfully usable throughout the year — whether you’re propagating, potting on or simply enjoying a quiet moment among your plants.

Made from Cedar

Alton Greenhouses are made from Canadian Western Red Cedar. Cedar is a very low maintenance timber, with fewer knots than Redwood or Whitewood, giving it a smoother appearance, making it ideal for painting.

Cedar has an attractive deep red colour, which silvers down over time, and contains natural oils which protect against wood rot, fungal disease & insect attack.

Cedar has higher insulative values than other timbers, and a desired service life in excess of 30 years with suitable maintenance. Alton Greenhouses are supplied treated in a clear wood preservative. We recommend that Cedar should then be treated with a solvent based wood preservative every 6 – 8 years to protect against moisture ingress.

Bar Capping

Alton’s Evolution bar‑capping system grips the glass tightly and uses it as part of the structure — eliminating rattles and dramatically increasing rigidity. Combined with thick cedar glazing bars and precision jointing, the result is a greenhouse that feels solid, quiet and built for a lifetime of growing.

Alton greenhouses come with Cedar bar capping as standard, but also offer an upgrade option to Aluminium bar capping. With this upgrade, you really can have a virtually maintenance free Cedar Greenhouse – and the stylish moss colour blends in perfectly with the Cedar as it ages to the distinctive silvery colour.

Installation & Base

Installation services are available via Bourne Buildings in some locations

Alton buildings need to be placed on a flat, level, compact (firm) base, with paving slabs or concrete being the best options.  The base should be the same size as the building itself*, level (with no drainage slope) with 2 inches above ground level to avoid surface water running underneath.

Alton Greenhouses can sit on either a solid paving or concrete base as described above, or on concrete strip footing. Dwarf wall models will require a suitable dwarf wall to be constructed – Exact measurements will be supplied once you have placed an order.

Clearance

We recommend at least 18” clearance all round for installation, airflow, and future maintenance. Victorian models: Please allow 24” clearance all round.

*Bases can be larger than the building if required by the customer but must not be any smaller.
