ThermoWood® is a modern construction material that is used only in Swallow greenhouses. Its fantastic qualities are put to good use when you consider an 8ft x 18ft Raven Greenhouse.
This is an attractive traditionally styled structure that is highly warp and rot resistant because the timber has been heat treated to remove moisture and resin it, therefore, doesn't expand or shrink and no preservatives are required.
Double doors mean getting into the greenhouse is easy even with large garden equipment or a wheelbarrow. Once inside you'll realise that this is a very productive growing area with six roof vents that automatically open and light flowing through the toughened glass that has been silicone sealed.
Staging is already in place along one side to assist sowing seed and potting, and you can choose to have a high shelf as well. Other options include a rainwater collection system for recycling and a Combination Shed that would offer storage and your working space.

Fast Free Delivery within Mainland England and Wales.
Inclusive delivery and installation are limited to mainland England, Wales and Scotland up to a maximum of 15 miles further North of Glasgow.
Unfortunately, Swallow greenhouses cannot be delivered and installed to areas of Scotland above 15 miles North of Glasgow, Scottish Highlands, Offshore Islands and Isles, Northern Ireland, or the Republic of Ireland.
Delivery will typically be made within 5 - 6 weeks for standard Thermowood and/or Oiled frames, and 10 weeks for painted frames.
Note: Some delivery locations such as Scotland, Devon, and Cornwall will naturally have extended delivery timeframes due to the additional distance required for the delivery and for our installation team to travel. This can be up to an additional 6 weeks on top of the standard quoted lead times.
All Swallow greenhouses are crafted to order, so may be extended during busy times of the year.
Bespoke Product Procedure
This product range is made to order on an order-by-order basis, therefore is exempt from our usual cancellation and returns policy. Any cancellations after your order has started production may not be able to be cancelled or may be subject to cancellation charges. Although a very rare occurrence, this does not affect any orders that arrive damaged or faulty, whereby our normal terms on receiving a faulty product will apply.
Vehicles We Use
Items will be delivered on larger lorries which can get to most places it's typically, a 7.5-ton lorry which is about the size of a dustbin lorry, this will depend on the item that is being delivered and should you have any concerns with restricted access to your property we ask you to contact us prior to placing an order.
Unloading Of Your Delivery
Back garden access is required from the front of the property, as due to the size of the product and the large sections that they are delivered in, the installation/delivery team are unable to carry these items inside your home as the sections are unlikely to pass through standard indoor door sizes. When the item is delivered on a pallet, the pallet and packaging are non-returnable. Goods can only be maneuvered on a flat and level surface (i.e. not a gravel driveway) by a pallet truck. If the installation/delivery team is unable to gain access to the installation area from the front of the property, they may not be able to complete the installation, and a cancellation charge may apply.
A suitable, flat, and level base must be prepared prior to the delivery and installation - please ensure that this is pre-prepared prior to the arrival of your greenhouse and the installation team.
