UNIQUE LOG CORNER ASSEMBLY: This quality garden room features a unique corner assembly system, which is both attractive and strong and combines the benefits of a log cabin with a conventional summerhouse. Each wall log slots into full length aluminium connector poles. The first log is laid at the bottom and the rest slot into each other, working upwards one log at a time. The aluminium is not visible inside and concealed outside by timber cover trims. The logs and the aluminium connectors are precision milled to ensure a neat fit. No screws or nails are required which makes installation easier and also allows for timber movement. The finished corner assembly is strong, weatherproof and draughtproof.
DOUBLE GLAZING: Our double glazed doors and windows ensure that your log cabin is warmer and cheaper to heat. We recommend double glazing if you want to use your cabin all year round. Double glazing also provides additional sound insulation. If you expect to use your cabin frequently and often for prolonged periods we also recommend floor and roof insulation. Insulation ensures a more comfortable environment on the hottest days in the summer and the coldest days in winter.
HEAVY DUTY TONGUED AND GROOVED FLOOR: The timber floor kit features tongued and grooved floor boards and substantial floor joists. Skirting boards are also included to ensure a neat internal finish. The floor joists and tongued and grooved boards are supplied loose for fast assembly on site. Unlike many log cabin floor kits all timber is cut to size which saves time during installation. It also ensures that there are no visible joins in the finished floor. The floor is assembled quickly with no visible joints. With some cheaper cabins only the joists are cut to size and the boards must be cut in on site. This takes much longer and many of the joins are visible afterwards.
PRESSURE TREATED FOUNDATION BEAMS: Substantial foundation beams are laid on the base to support the walls. This ensures that the wall logs are not in contact with the ground. The foundation beams are pressure treated for durability. Pressure treatment is a lifetime preservative treatment. The preservative is forced into the timber under pressure in a vacuum and penetrates below the surface. All other treatments apply a coat of stain to the surface of the timber only. With pressure impregnated timber, the chemicals are permanently fixed in the wood. Tanalith E is the most popular preservative used so pressure treated wood is often described as tanalised. With the foundation beams this log cabin can be built without a floor. If required a timber or concrete floor can be laid inside after the walls and roof have been fitted.
JOINERY DOORS & WINDOWS: These log cabins feature joinery made door leaves and window sashes with morticed and tenoned joints throughout. This traditional jointing process is commonly used in the housebuilding industry when timber windows and doors are specified. A rebate or mortice is cut out in one piece of wood which precisely matches a tongue or tenon cut in the other piece of wood. Morticed and tenoned joints are the strongest type of joint used in the construction of wooden windows and doors. High quality handles, locks and hinges are also included.
HIGH PERFORMANCE DOORS AND WINDOWS WITH WEATHERSTRIPS: Our high performance premium window and door frames feature weatherstrips to reduce draughts. Weatherstrips are rubber gaskets which are fitted to the door and window frames. The weatherstrips are fitted in the rebates between the fixed outer frames and the hinged parts i.e. the window sashes and door leaves. As the doors and windows are closed the weatherstrips are compressed to form a seal. Heat loss is significantly lower through windows and doors which are fitted with weatherstrips.
DECORATIVE FELT TILES: Mineral coated bitumen felt tiles are an attractive and durable roofing material which is far more hardwearing than standard roofing felt. Traditionally used for small buildings only in the UK, felt tiles are used much more in Scandinavia and North America where they are used widely in general housebuilding. The sophisticated design features a strip of almost dry bitumen adhesive. Over time each tile sticks to the tile below for improved waterproofing and windproofing. All fixings are covered by the next row of felt tiles, partly to ensure a neat appearance with concealed fixings but mainly to protect the fixing holes from any possible moisture. Mineral felt tiles are made using asphalt with a bitumen binder and an external covering of durable and attractive natural stone chips. Mineral felt tiles are often described as felt shingles because the design resembles traditional cedar shingles.
OCTAGONAL BUILDING SIZES: For ease of reference these octagonal log cabins are measured as a rectangle. The first dimension listed is the overall width from side to side and the second dimension is the depth from front to back. The external wall sizes are listed alongside the price. These sizes do not include the roof overhang. Many other suppliers quote the overall roof size which is much larger.

TRANSLUCENT WOOD STAIN TREATMENT - FACTORY FINISHED: This high quality preservative finish is professionally spray applied in the factory to both sides of the timber. The cabin is treated inside and out in a choice of colours. You can choose one or two of our colours. The doors and windows can be sprayed the same colour as the wall logs and roof or painted a different colour. Treatment of the roof includes the rafters and boards. Microporous woodstains offer superior protection plus greater durability. Microporous woodstains are impervious to water but not to water vapour, which allows the wood to breathe. Colours are only as accurate as reproductive techniques allow.
SEMI OPAQUE PAINT TREATMENT - FACTORY FINISHED: This high quality preservative finish is professionally applied in the factory. A colourless basecoat is applied to both sides of the walls. Then a semi opaque paint treatment is applied to the outside of the wall logs and to the doors and windows. You can choose one or two of our colours. The doors and windows can be painted the same colour as the wall logs or a different colour. Microporous woodstains offer superior protection plus greater durability. Microporous woodstains are impervious to water but not to water vapour, which allows the wood to breathe. Colours are only as accurate as reproductive techniques allow.
MICROPOROUS PRESERVATIVE - DELIVERED TO YOUR DOOR: Our quality microporous preservatives are impervious to water but not to water vapour. This allows the wood to breathe. You can order up to 3 separate colours if required. At least two coats are normally required with a further coat at periodic intervals.
Our 3 star preservative is practical and affordable with a choice of 4 colours. It covers around 10 square metres per litre and normally lasts 1-2 years before a further coat is required.
Our 4 star preservative is a high quality preservative which covers around 9 square metres per litre and normally lasts 2-5 years before a further coat is required. It is available with a choice of 12 colours.
Our 5 star preservative is a deluxe high build preservative which can be used to achieve a stunning finish. Each extra coat increases the colour and sheen. It covers around 8 square metres per litre and normally lasts 2-5 years before a further coat is required. It is available with a choice of 12 colours.
Based on average coverage five litres of our 4 star preservative is enough for two coats on an 8'x10' shed or an 8'x8' log cabin. Ten litres is enough for three coats on a 10'x16' shed or a 12'x10' log cabin. Coverage varies according to the smoothness of the surface and the porosity of the timber. We recommend that you order more than you need to be sure that you have easily enough. All of these preservatives are safe for use with children and pets. These microporous preservatives are only available when you purchase a Summer garden building or if you purchased a Summer building in the past. Prices include free mainland delivery to England, Wales and southern Scotland. Colours are only as accurate as reproductive techniques allow.
WATERPROOF COLOUR SEAL - DELIVERED TO YOUR DOOR: This advanced water-based microprous timber treatment uses the latest high-tech nanotechnology to create a long-lasting waterproof wood coating that is environmentally friendly. It is suitable for use on all softwood and hardwood products and is especially recommended for use on pressure treated timber, including sheds, summerhouses, gazebos, fencing and garden furniture. This timber treatment will colour, protect and enhance your exterior wood. It contains a mould inhibitor to protect the coating and can be used on all outside and inside timber. It gives a traditional matt wood stain finish in a range of natural colours. It can easily be applied by sprayer, brush or roller. It is recommended that the second coat is applied as soon as the first coat is touch dry. We advise for ultimate performance the timber has a wood preservative pre-treatment. For the first treatment, two coats are recommended and will give a traditional wood stain finish that is long lasting. A further coat is recommended every 2-5 years. One litre covers approximately 10-12 square metres. Coverage varies according to the smoothness of the surface and the porosity of the timber. On average five litres covers a 12x8 shed with two coats and ten litres covers a 10x20 with three coats. It is recommended that 2 coats be applied. We recommend that you order more than you need to be sure that you have easily enough. Colours are only as accurate as reproductive techniques allow. Prices include free mainland delivery to England, Wales and southern Scotland.
WATERPROOF CLEAR SEAL - DELIVERED TO YOUR DOOR: Our hardwearing clear seal is ideal as a clear varnish for bare timber or as a waterproof top coat for painted wood and pressure treated timber. It is also ideal as a waterproof floor varnish, especially the polyurethane clear seal. The smooth and shiny finished surface is waterproof and easy to clean. Available in a choice of acrylic or polyurethane, these colourless water based coatings are almost odourless and recommended for smooth planed timber only. One coat is normally required as a sealing top coat on painted or treated timber. A minimum of two coats are normally required on untreated wood. Up to three coats may be required for floors. An unsealed timber floor quickly shows muddy boot marks and other dirt. For best results a floor should be treated at the earliest opportunity while the timber is new and clean. On average five litres of our 5 star clear seal is enough for three coats on a 12'x12' floor, two coats on the walls of an 8'x8' log cabin or one coat on the walls of a 12'x16' log cabin. We recommend that you order more than you need to be sure that you have easily enough. The price includes free mainland delivery to England, Wales and southern Scotland.
UNDERFLOOR INSULATION: The underfloor insulation is designed to suit our timber floor. The rigid insulation boards are suspended between the floor joists and above the ground. The top face of the insulation is just below the floorboards. The solidity of the floor is unaffected by this design. The internal appearance is also unchanged with attractive and durable tongued and grooved boards. Detailed instructions are supplied. The floor insulation used is 25mm thick polystyrene which is certified by the British Board of Agrement.
ROOF INSULATION: The roof insulation is laid over the roof boards and below the roofing felt. This ensures that the internal appearance is unchanged with attractive tongued and grooved boards visible inside. No internal lining boards are required. The roof insulation kit includes rigid foam boards which are lightweight and easy to install. Longer felt nails are included for fixing the roofing felt or felt tiles through the insulation. Detailed instructions are supplied. The roof insulation is 50mm thick polyurethane foam with reflective silver alloy laminate facings on both sides. It is certified by the British Board of Agrement. The roof insulation increases the ridge height by approximately 50mm which may be of critical importance if you need to keep the overall height below 2.5m for planning purposes.
RECYCLED PLASTIC BASE KITS: Our durable eco-grid and eco-paving base kits are a practical and affordable alternative to slabs or concrete. Lightweight and easy to install within a few minutes, these 100% recycled polypropylene pavers simply click together with no fixings needed. The interlocking design helps to spread weight and ensures greater rigidity. Extensive preparation is not normally required - just level the soil and lay the pavers directly on soil or a thin layer of sand or pea shingle. Weed membranes are not needed below a timber floor. The self draining design prolongs the life of a timber floor. Unlike paving or concrete our plastic bases are fully relocatable. Where space permits the base is normally laid full size but if required in a tight location the pavers can be cut to size with no loss of structural integrity. The base is normally a few inches larger than your building. Fast delivery within 3-5 days ensures that you can start work quickly.
ECO-GRID BASE KITS: Our eco-grid plastic bases can support up to 150 tonnes per square metre. Each eco-grid is 472mm x 472mm and 40mm thick with an immensely strong 60mm hexagonal cell structure. Eco-grids should be laid on a sub-base of soil, sand or pea shingle but not on hard surfaces such as concrete. Integral pegs on the underside help to bed the eco-grids into a softer sub-base which helps with levelling. If the sub-base is concrete or a similar hard surface we recommend our eco-paving which features a flat underside.
ECO-PAVING BASE KITS: Our eco-paving is less brittle and more difficult to damage than concrete paving slabs. The pavers have a strong grid structure underneath and the surface looks similar to concrete slabs. Eco-paving is recommended if the sub-base is concrete or a similar hard surface, because the pavers feature a flat and level underside. Eco-paving can also be laid on soil or pea shingle. Each eco-paver is 385mm x 385mm and 40mm thick.
WPC COMPOSITE DECKING KITS: This superb quality WPC wood plastic composite decking closely resembles real wood, with the same look and feel. However, it is virtually maintenance free and it will never rot. At a glance it is difficult to tell the difference between this composite material and real timber decking with a stained finish. Furthermore, the similarities are not skin deep like a thin veneer. The realistic finish has a fibrous surface which looks similar to the grain of real wood. This synthetic composite is also heavier and stronger than real wood. The strength, durability and lack of maintenance make this superb decking a popular choice with pensioners and discerning commercial buyers such as care homes. Occasional cleaning with soapy water normally restores the original appearance. If any dirt or stains become ingrained after prolonged neglect even the most stubborn marks can be cleaned with a pressure washer.
Our WPC composite decking is a revolutionary material which provides all the benefits of real wood without the maintenance. It can be left outside uncovered all year round. Unlike real wood this synthetic wood is a weatherproof material with no knots, splinters, machining marks or other imperfections. It will never develop splits or shakes and no sap will ever ooze out of it. Our wood plastic composite is an equal mixture of real wood and recycled plastic. Even the wood is a mixture of sawdust and unusable offcuts, so it is the ultimate environmentally friendly alternative to wood. The colour pigments are mixed in before the powdered composite is moulded into shape, so the colour runs all the way through the finished product. The boards are completely impervious to water. The boards can be sawn, drilled and screwed, just like real wood. You can fix it with standard woodscrews. Being heavier and denser than real wood, screw fixings are actually stronger in composite boards.
BURGLAR ALARM: This simple and effective battery operated burglar alarm kit is easy to install in any wooden garden building. The main panel features a digital keypad and a powerful built-in siren. Two pre-wired door contacts are also included complete with a length of cable which plugs into the main panel. A 9 volt PP3 alkaline battery is required, which is not supplied with the kit. The alarm is easy to set using the digital keypad. A delay allows plenty of time to enter or leave the building after setting the alarm. Once the alarm has been armed it will be triggered by opening the door or tampering with the wiring. When the alarm is activated the siren emits a powerful and unpleasant sound to deter intruders.
SOLAR POWERED LIGHTS: These ingenious and affordable solar powered lights are easy to install with no mains wiring and they cost nothing to run. During the day the externally mounted solar panel converts daylight into electricity and recharges the batteries. The solar panel is weatherproof and suitable for outside use. It is normally positioned high on the walls of your log cabin or on the roof. Our solar internal lights solve the problem of seeing inside your log cabin at night. Our solar security lights illuminate the approach to your log cabin at night and may also deter burglars. After dusk the passive infra red movement detector switches itself on when it detects movement. The more expensive solar lights are brighter and stay on for longer.
- Delivery is normally between 10 and 12 weeks after order.
- Our log cabin prices include all delivery charges - unlike others we do not add delivery charges during the checkout process.
FREE CRANE OFFLOAD: The delivery lorry normally includes a crane to unload your log cabin quickly and easily without assistance. There is normally one pack which is unloaded on the drive or verge at the front of your property. Pack sizes vary from around 3.5m long for a small cabin to 5.5m long for a larger cabin. The packs are polythene wrapped and securely strapped while in transit but after the pack is opened the individual components are easy to carry. The wall logs can be carried one or two at a time and all packages are designed to pass through a normal single door.
RESTRICTED ACCESS: The delivery vehicle is a large lorry, typically around 50' or 15m long and 9' or 2.7m wide, which is unloaded from the side. If there is no suitable unloading area at your property the driver can park several hundred yards away and carry the cabin with the forklift. The fork lift can carry the cabin sideways or end on so it can carry a long pack up a narrow lane. Although the tyres are all terrain the fork lift requires a firm and flat route from the parking area to your property with no steps or steep slopes. With advance warning we can normally overcome most access restrictions, often at no extra cost. Please contact us if you have any concerns regarding the access at your site.
DELIVERY TO SCOTLAND: Although southern Scotland is inside our normal delivery area we can also deliver to other parts of Scotland. The delivery period may be a week or two longer and there may be additional delivery costs. Please phone 01603 721590 for further details.
