Wooden summer house M735 – 370 x 360 cm – 13,24 m2
Create extra garden space with the TIMBELA M735 Wooden Summer House. This 12×12 ft garden building is suitable as a bright garden retreat, hobby room, teen leisure area or practical storage space for items that no longer fit in the home or garage.
Large windows help fill the interior with natural light, giving the building a more open and inviting feel than a basic garden shed. A ventilation grille is included for air circulation.
This summer house uses a sturdy timber frame construction. 30 x 60 mm timber frame sections are joined together to form a stronger 60 x 60 mm frame structure. Combined with 17 mm wall boards, this gives the garden building added stability, while the roof has a snow load rating of 160 kg/m². Suitable internal insulation can be added if required; insulation materials are not included.
A complete roof covering set is supplied as part of the kit: 12 mm OSB roof boards, bitumen underlay and grey hexagonal bitumen roof shingles.
Important: assemble on a prepared, solid and level base with a moisture barrier between the base and wooden walls. Untreated pine/spruce wood should be treated or painted according to the care instructions.
Includes wooden parts, fixings, hinges, handle, lock, keys and printed assembly instructions. Standard 2-year warranty applies; see product documentation for full terms.

InstructionWe only use high-quality FSC® C110730 certified dried and planed pine/spruce. High-quality wood has minor and fine branching, smooth and light color. Wood is a natural raw material that varies according to natural weather conditions.
Therefore, small cracks and discoloration are not defects in the wood but characteristics of the wood as a natural raw material.
The small gaps that appear between the boards are also a reaction of the natural material. If the product has been properly treated, after some time the wood’s “movements” stop.
Due to the natural characteristics of the wood, product dimensions may vary by 1–2 mm.
Untreated wood can turn blue or grow mold. To protect the wood, you must coat the wooden parts on all sides with a wood impregnator before assembling the product.
It is possible to distinguish shades between the different boards. But these differences are reduced with sunlight. It has no effect on the product stability.

Untreated wood can develop blue stains or mold. To protect the timber, you must apply a wood preservative to all wooden parts from all sides before assembling the product. The treatment must be done only when the wood is completely dry. Treating or painting damp wood poses a high risk of mold growth.
We recommend repainting the house every 3 years, or more frequently if needed.
Proper ventilation is essential to prevent moisture buildup inside the wooden house – ventilate regularly and ensure air can circulate freely.
To ensure the longevity of your wooden house, we recommend performing the following checks at least once per season:
– Inspect for any cracked or damaged boards.
– Check the condition of the roof covering – look for damage or gaps that could let water in and damage the structure.
– Look for signs of moisture accumulation or mold.
– Remove any debris or fallen leaves around the base of the house – this helps prevent moisture buildup.

Installing a garden house begins with preparing a perfectly level and square foundation. The minimum distance between the upper edge of the foundation and the first wall/floor element of the garden house should be 45 mm. Pouring a concrete foundation is not essential for that purpose, lightweight construction blocks, concrete slabs or posts are also suitable as a base. A damp-proof barrier should be used between the foundation and the wood structure. When choosing a spot for the hut, please make sure the hut will not be exposed to extreme weather conditions (strong winds or snow). Otherwise, you should additionally use anchors.
A roof felt as a covering material (if included in the set) is designed for short-term (1 year) use only. If you want to protect your garden house roof from moisture and adverse weather, you must apply additional final roof cover (example – bituminous roof shingles). When installing the roof felt overlap between pieces must be min 8cm.
