Yes, you can easily assemble a 3x3 m garden house, if you are equipped with some tools, normally owned by a handyman.

The assembly costs depend on size, type, location and other factors. For further information, ask your dealer.

Because of our very large range and many types it is impossible to make a plan for every single type. If the assembly turns out to be a bit complex for you, we recommend to have the assembly done by our assembly service. Our professionals have experience, it is their job.

15. Is it best to provide a wooden or a concrete floor?

No, all parts are custom-made and for own production only. Loose parts cannot be supplied separately and are always part of a unit.

26. Can I paint my garden house?

Yes, but the paint must be damp controlling so the wood can still breathe. Autoclave-treated wooden garden houses must be left untreated for at least the first 3 years. Afterwards, they can be freshened up with garden oil! Garden houses made of cedar wood are best left untreated to weather naturally. You can and may treat them, but special oil adapted to cedar wood should be used!

27. Is it normal that the inner construction of my cedar garden house is made of whitewood?

Due to manufacturing and technical (solidity) reasons, the inner construction is always made of pinewood. The inner construction thus differs from the wood type chosen by the customer.

28. What material are the support beams and cornices made of?

Depending on the chosen wood type, the support beams and cornices are either made of the same wood type, or of an equivalent and equally durable wood type. Certain wood types (e.g. iroko) are not appropriate to be used for support beams or cornices.

29. Is your garden house ready for winter?

Winter is coming! Time to move all your outdoor furniture, garden tools and barbecue to the garden house. To make sure all of it is in a good condition after winter, we recommend to give your garden house a proper maintenance before the typical winter conditions really set in.

1. Remove moss from roof and gutters

The growth of moss on roofs and gutters is not abnormal. Nevertheless, removing it has both an aesthetic as a functional value. Rainwater no longer remains on the roof and in the gutters, so internal moisture has no chance. A simple and quick job that only requires a brush, and a mixture of water and bleach. Remove dead leaves and twigs from gutters to avoid obstructed drains. Your roof will look brand new.

2. Check the roof sealing (EPDM roofing)

Water can enter your garden house through loose seams and poor roof sealing. To avoid problems, check your roof on the presence of cracks or other irregularities. Loose seams or cracks can be repaired with rubber tape. Bubbles must be cut open and repaired with rubber paste. Said repairing products can be purchased at DIY shops. If you don’t want to do it yourself, you can get help from a professional.

3. Lubricate lock and hinges

In general, garden house doors have three hinges. Use oil to lubricate the hinges as well as the rail of the sliding door, if any. Use a silicon spray to lubricate the lock bearings and the key itself. Next, turn the key to open and close the lock a couple of times to ensure a smooth performance.

4. Apply stain to the wood

Recently installed garden houses must be treated inside and outside with coloured oil or stain for outdoor use. Never paint nor varnish the wood because it stops it from breathing and results in moisture accumulation.

5. Proper venting

Good venting during winter times results in less condensation. Remember to regularly open the windows (tilt position or similar) or install an extra ventilation grid.

30. Can the concrete flooring be larger than my garden house?

No, the sizes are indicated and are always smaller than the volume of the garden house and at least 5 cm higher than the ground level. The same applies for additional terraces. However, they cannot be poured at the same level, they must be at least 5 cm lower!

31. How to avoid water splashing around your garden house?

By providing a gravel path (5 cm below the concrete slab) around the garden house, splashing water, soil or sand can be avoided. This lengthens the life of your garden house. Also read about maintenance.


32. On the outside of my flat roof garden house, I see the metal plate that is used for the roofing. Is this normal?

Ceilings are only installed on the inside of garden houses, never on the outside. Therefore, it is absolutely normal to see the metal plate used for the roofing. Moreover, for reasons of rainwater discharge, the fascia board is never installed right against this metal plate


33. Should I check my garden house with a spirit level?

A garden house is a wooden construction and wood is a yearround living material. A garden house expands in winter and shrinks in summer. When assembling, we always aspire to obtain a great visual result. Therefore, it is kind of pointless to verify the construction with a spirit level after its assembly.


34. There’s a ventilation gap all around the bottom of my garden house. Is that normal?

Yes, garden houses with wooden floors must be ventilated to prevent mould and wood rot.

35. Is it okay to leave my non-assembled garden house in the garden for a longer period?

All panels of your garden house are supplied in a horizontal position on a pallet. All parts are wrapped in shrink foil. After delivery, it is advisable to place the wrapped panels upright in a place completely protected against sunshine and rainfall. We recommend not to wait for weeks or months to start assembling the garden house. Moreover, it is a bad idea to remove the panels’ packaging and to put them in your garden where they are exposed to the elements of nature. We strongly recommend to start as quickly as possible with the assembly of your garden house, followed by the roofing.
