Terrace package (16.2x1.2 m)
A terrace is a valuable addition to your wooden house. It offers maximum functionality, a beautiful design, and optimal comfort. Made from sturdy natural softwood, it allows you to expand your living space and spend more time outdoors.
Our terraces, crafted from thick planks of high-quality softwood, are easy to install yourself. Of course, you can also opt for our professional installation service.
A terrace with direct access from the main entrance provides the perfect spot to enjoy a morning coffee, soak up the sun during the day, have cozy family dinners and barbecues, and relax in the evening while watching the sunset.
Would you like to enhance your home with a terrace? Our friendly team is ready to answer all your questions. Contact us today via email or phone.
SIP floor - 174mm (Insulated)
The 174mm SIP-insulated floor package is suitable for homes on ground screws or PVC floor supports. This system provides excellent insulation and stability.

SIP floor - 174mm (Insulated)
Wooden frame base
As an alternative to our concrete foundation, we offer a custom-made and pre-treated wooden frame on which our buildings can be mounted.
The wooden foundation offers the following benefits:
It helps level the ground and prevents moisture penetration.
It is an excellent solution when a concrete foundation is not an option.
It is more affordable and quicker to install than a concrete foundation, requiring fewer building materials.
It is ideal for creating a larger surface area that can be extended into a terrace or seating area.
We offer two different options for the wooden foundation:
With PVC floor supports
With METAL screw foundations
What is the difference?
The wooden frame with PVC floor supports can only be placed on a flat surface (such as compacted soil, concrete blocks, paving, or metal or concrete posts). In contrast, the foundation with metal screw foundations can be installed regardless of ground level. Choosing metal screw foundations generally simplifies the construction process and saves time and money. Additionally, using metal screw piles allows for quick installation, as the foundation is ready for use immediately after setup.
The wooden frame consists of:
Wooden beams (44x140 mm)
Adjustable floor supports or metal screw foundations (depending on the chosen option)
Screws (4x50 mm)
Screws (6x120 mm)
Breathable membrane

With metal screw foundation (5.7x11.7m)

With PVC floor supports (adjustable support) (5.7x11.7m)

The base structure is made of 28 mm thick wood, complemented by 20 mm thick roof planks.
Please note that the installation of accessories is only possible if you have also selected the installation of the main product.
Storage 2.7m x 1.6m
This storage unit, made from slow-grown softwood, is our most popular accessory due to its excellent functionality. Customers appreciate the extra storage space it provides and the ease with which it can be attached to any of our cabins and garages. The construction consists of 28 mm thick wall planks, while the roof and floor are made of 20 mm thick tongue-and-groove boards. With external dimensions of 161 cm in width, 273 cm in depth, and 190 cm in height, this storage unit offers ample space for all your belongings.
