Granny Annexe Julia (34 mm + cladding), 22 m² £6,940.00
  • Bitumen roofing shingles + underlay

    These shingles have a fiberglass mat base and are coated with a durable bitumen mixture on both sides. The bottom layer consists of cold-resistant, self-adhesive bitumen, ensuring a strong bond to the roof surface. The top layer is finished with mineral granules, providing both protection and an attractive appearance.

    Superior Quality
    Bitumen shingles guarantee quality, backed by the international ISO 9001:2008 and the European standard EN544. They are resistant to open flames and offer significantly better heat and sound insulation compared to other roofing materials.

    Easy Installation
    Applying bitumen shingles is simple. Remove the protective tape from a single sheet, place it on the roof, and secure it with nails. This makes the installation fast and easy.

    Underlay
    We also offer an underlay (1 x 10 m) that can be placed beneath the roof shingles. This underlay extends the lifespan of your roofing material and helps it maintain a beautiful appearance for longer.

    Colorless water-based primer for indoor use

    Treat your log cabin with an eco-friendly and transparent coating. This treatment is ideal for protecting the interior of your log cabin or wooden garage. It contains ingredients that are gentle on both you and the environment while providing protection against mold. Unlike other treatments on the market, this solution is almost odorless. It is supplied in cans and should be applied after the building is completed.

    The treatment provides only initial protection for the wood against rot, mold, and insects. It does not fully protect the cabin from external influences; therefore, paint or wood protection should be applied afterward.

    Remmers Paint

    Remmers is a paint that offers high durability and protection for wooden surfaces. The semi-matte finish is available in three colors: transparent, brown, yellow, or white. Thanks to REMMERS technology, the paint remains intact under all weather conditions and will not peel or crack over time. Additionally, the wood becomes more resistant to water damage.

    Technical Information:

    • Density: Approx. 1.3 kg/l, ISO 2811
    • Solid Volume: Approx. 41%

    This paint is suitable for untreated natural wood or surfaces previously coated with other paint. It can be applied using a spray, brush, or roller. The paint dries within just one hour and requires an interval of two to four hours between coats under normal weather conditions. Please note that drying time may be longer in humid environments.

    The paint is supplied in cans and should be applied after the completion of the building.

    PVC Windows and Doors

    Enhance the Insulation of Your Cabin or Garage with UPVC Windows and Doors from Wink Haus®

    These gray windows and doors with a white interior are manufactured in Germany and utilize the advanced KBE system_70 technology. UPVC windows and doors feature a 70 mm profile with 5 chambers and 24 mm double glazing filled with argon gas. This ensures maximum thermal and sound insulation, with a noise reduction level of up to 35 dB.

    German Quality

    Wink Haus® is a family-owned company founded in 1854 with extensive experience in manufacturing windows and doors. The quality of their products is certified by multiple standards, including ISO 9001:2008, ISO 14001:2004, DIN EN ISO 9001:2000, and DVC 189G.

    Installation Service

    If you order an installation service for a cabin, the installation of PVC windows and doors will cost an additional 8% on top of the total installation price for the cabin or garage.

    Floor: 18-20 mm wooden floorboards, crossbeams, and skirting boards

    Floor Sets for Every Need

    Our floor sets are designed for optimal durability and include pressure-treated foundation wood (crossbeams) to ensure the longevity of the wooden structure. Each set includes skirting boards, 18-22 mm kiln-dried wooden floorboards, corresponding nails and screws, and, depending on the house design, the necessary insulation.

    Various Options

    We offer three different versions of our houses, each with matching floor sets:

    • Simple Houses Without Insulation: The floor set for these houses does not include insulation.
    • Insulated Holiday Homes: This floor set includes 50 mm floor insulation to maintain a comfortable temperature.
    • Extra Insulated Homes: For these houses, the floor set includes 100 mm thick insulation and elevated foundation supports for extra protection and stability.
    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

    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.
