Description
The Swallow Mallard 8t x 20ft greenhouse comes as a t-shape design with a front porch, not only offering a mammoth place to grow all of your favourite plants and flowers but will make a magnificent addition to your garden. It's classically styled and built to last with highly durable Thermowood®.
Thermowood is Scandinavian timber which has been heat treated to remove moisture, it has minimal expansion and shrinkage, and therefore is highly unlikely to warp. The wood is also rot-resistant and doesn't need to be treated with preservatives, making it ideal for long term use outdoors.
Four opening vents create a lovely flow of air that your plants will certainly appreciate, and 3mm toughened real glass glazing lets in masses of light. Inside you'll find two front returned stagings as standard, although more for the rear can be added, as well as shelving throughout.
The greenhouse is illustrated in the photos as being both the standard wood boarded base, and the alternative build sited on a brick dwarf wall. As standard the building is constructed on a boarded base, but you can select the dwarf wall option below at no extra cost. Both are very attractive and are designed to support your garden preferences.
Please note: The imagery on this page shows the Swallow Mallard Greenhouse in multiple sizes and colour variations.

Select Your Options
Choose Your Build Design
Choose from the standard freestanding build with wooden boards, or select the dwarf wall build option if you plan on having your greenhouse on a brick dwarf wall.
If you decide on the dwarf wall version, a wall height of around 607mm will need to be built beforehand by yourself, in which a wall plan will be sent to you in advance to pass onto your builder in order to construct the wall to the correct dimensions. Your greenhouse will then be installed sited on top of the wall.

Choose Your Colour Finish
Oiled Finish - Upgrade to an oiled finish to receive the same benefits of Thermowood from the standard finish, plus an an added oiled coating.
The oiled finish will help to protect the timber even further, and lasts for 12 months on average before requiring retreatment for continued protection.
Painted Finish - Alternatively, upgrade to one of the painted colour finishes which utilises standard Thermowood, along with two topcoats and then glazed and sealed in your chosen colour. On average, the painted colour finish will persist and protect the greenhouse for around 3-5 years before requiring repainting.

Delivery Information
Delivery & Installation Overview
Where We Can Deliver To As Standard -
Inclusive delivery and installation is available to the majority of mainland England, Wales and Scotland up to a maximum of 15 miles further North of Glasgow.
Where We Can Deliver To That Requires An Additional Surcharge -
An additional surcharge will be applicable for Swallow greenhouse delivery and installations to areas of Scotland above 15 miles North of Glasgow or the Scottish Highland, if the location is available to service, and isn't part of our exceptions listed below. For serviceable locations, the surcharge price can be found under the ‘Delivery & Install Options’ above, and this option will need to be selected upon ordering.
Where We Are Unable To Deliver To -
Unfortunately, delivery and installation cannot be carried out to the following locations due to service limitations:
- All IV Postcodes
- All HS, KV, ZE Postcodes
- All PA Postcodes
- Limited PH Postcodes
- KA27 and KA28 Postcodes
- Any Other Offshore Islands and Isles
- Northern Ireland
- Republic of Ireland
Delivery & Installation Timeframe
*Delivery and installation will typically be made within 8 - 12 weeks to the majority of England and Wales locations, along with Scotland, Devon and Cornwall.
Delivery timeframes start from when confirmation has been submitted that your base area is prepared and ready for installation of your new greenhouse, and not from the date of your order being placed.
Both the delivery of your new greenhouse and the installation service will be completed at the same time and so the installation team will be the ones to deliver your greenhouse when they arrive to install it.
All Swallow greenhouses are crafted to order, so maybe 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.
Pay In Full or Pay Just a 20% Deposit
On our Swallow greenhouse range we allow the ability to pay in full at the time of ordering, either online through our website or on the phone. Or alternatively, we can arrange to confirm and take your order with just a 20% deposit taken at the time of ordering, with the remaining balance to be paid on the day of your greenhouse delivery and installation. If you'd like to order your Swallow greenhouse today by paying a 20% deposit, simply give us a call on 0121 355 7701 so that we can send you over a unique order invoice for your deposit payment, and all of the handy details relating to receiving your new greenhouse.
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 or rebooking charge may apply.
Base Preparation
A suitable, flat, and level base must be prepared prior to the arrangement of delivery and installation, which can affect the delivery and installation timeframe - so please ensure that this is pre-prepared as soon as possible so that your greenhouse can begin production. The installation team will contact in advance and will request a photo of the proposed installation area before being able to confirm a delivery and installation date. This is to ensure that the area is ready and suitable, ensuring successful installation on the day.
Dimensions do not include any applicable overhang or guttering, so please ensure that there is sufficient space around your proposed greenhouse base without obstruction, for it to be sited and installed successfully.
