FREE SAME DAY INSTALLATION - THE BENEFITS: Our free in house installation service is not just convenient, it is also your assurance of a better quality garden shed. This is because any building which includes free installation is invariably better made using quality components. Over time regular feedback from fitters ensures that design faults and weaknesses have been rectified. Same day installation is convenient for you and cost effective because it saves travelling costs. The fitters will deliver your garden shed and then install it, all at the same time. Others send sub-contract fitters separately, often from far away and often a week or two after the delivery. Waiting for the fitter can be very frustrating. Sub-contract fitting is also much more expensive because of the travelling costs. The fitting service does not include base preparation. A flat and level base is required, which can be made using concrete, paving slabs, pressure treated timber or plastic. In many areas we offer a base laying service as an option. We also offer heavy duty plastic base kits in all areas.

THERMALLY MODIFIED TIMBER: Thermally modified timber is a beautiful natural material with a projected service life of 30 years or longer. Only heat and steam are used in the treatment process and no chemicals are added. It is a lifetime preservative treatment. The timber is gradually heated to a high temperature which permanently changes the physical properties of the wood. The resistance to decay and stability of the wood are significantly improved as are the insulation properties. The moisture content is reduced and resin is removed so it cannot seep out of the wood. The process was developed in Finland but it is based on ancient knowledge. For example, the Vikings knew that fencing poles with a burnt surface were more durable. The finished colour of the wood is an attractive brown which can be painted or stained just like any other wood. If the wood is left untreated it will fade over time to a silver grey colour in the same way as other timber.

TOUGHENED SAFETY GLASS: Toughened safety glass is around 6 times stronger than normal glass so it is less likely to break. When it does break, toughened glass breaks into harmless small pieces. This makes toughened glass the best option for all the family including children, pets and the elderly.

SIZES - LENGTH AND WIDTH: The sizes are listed alongside the price. The first dimension listed is the width and the second dimension is the length. The width refers to the angled gable walls at the front and rear including the door wall. The length refers to the side walls. The sizes listed are the external wall sizes. These sizes do not include the roof overhang. Many other suppliers quote the overall roof size which is much larger.

COLOURED PAINT FINISH: This greenhouse is available treated inside and outside with a high quality microporous paint system in a choice of opaque colours. Microporous woodstains are impervious to water but not to water vapour, which allows the wood to breathe. Microporous woodstains offer superior absorption and protection plus greater durability. Colours are only as accurate as reproductive techniques allow.

HEATERS: We offer a huge range of heaters so whatever your specific requirements we have a heater to do the job. Our electric heaters require a standard domestic 13 amp electricity supply. Our propane gas heaters require permanent trickle ventilation when in use. As an approximate guide, a 3kw heater will heat a greenhouse up to 8'x12' or provide frost protection only up to 10'x15' in normal site conditions. A 1.5kw heater will normally heat a greenhouse up to 6'x8' or provide frost protection only up to 6'x12'. Internal partitions are often used in large greenhouses to create a smaller warm room which is cheaper and easier to heat.

HEATING REQUIREMENTS: Heating requirements vary for several reasons. Location is one factor with more heating required in Scotland than in southern England and less heating required in a sheltered position. The design is also a factor. For example, dwarf walls improve the insulation and lean to greenhouses absorb warmth from the existing wall. Another factor is the materials used. Polycarbonate greenhouses retain heat better than glass and wooden greenhouses retain heat better than metal greenhouses. We recommend you to buy a bigger heater than you need - you can always turn it down.

RECYCLED PLASTIC BASE KITS: Designed to spread weight and quickly clipped together, each paver is 500mm x 500mm. These durable and eco friendly plastic pavers are made from 100% recycled polypropylene. Lightweight and easy to install, the finished base will outlast any garden shed. Extensive preparation is not normally required - just level the soil and lay the pavers directly on the soil. No sand or shingle is required. Weed membranes are not needed below timber floors. Unlike paving or concrete these bases are self draining and fully relocatable. Our standard pavers support 150 tonnes per square metre. They are suitable for any normal use and they can be laid on a soil or shingle sub-base. Our heavier duty pavers support 350 tonnes per square metre. They can be laid on any flat surface including concrete. Where space permits the base is normally laid full size but if required in a tight location the pavers can be easily cut to size with no loss of structural integrity. These heavy duty pavers are only available when you purchase a Summer garden building. Fast delivery within 3-5 days ensures that you can start work quickly.


  • Delivery is normally between 5 and 8 weeks after order for unpainted garden sheds.
  • Delivery is normally between 6 and 9 weeks after order for painted finish garden sheds.
  • Our garden shed prices include all delivery charges - unlike others we do not add delivery charges during the checkout process.

SPECIALIST DELIVERY SERVICE: These garden sheds are normally delivered by the fitters in dedicated vehicles. This ensures less damage and no delay between delivery and fitting. Most cheaper garden sheds are delivered by national carriers who normally deliver to the kerbside only. Carriers cause more damage and normally refuse to carry glass or large panels. Their prices are based on weight and panel sizes. As a result, garden sheds delivered by outside carriers are made in small and flimsy lightweight sections with less wood. The benefits of our specialist delivery service include less damage, larger more rigid panels and heavier construction.
