More information

The Diana garden house is ideal as either a holiday home or a permanent abode on its own plot, for close family, relatives or tenants. One of the many fantastic features of the Diana Garden house is the glass wall of sliding doors that creates a light and airy space offering easy access to the surroundings. The house also features a kitchen or bedroom, a bathroom and a sleeping loft upstairs. Here you can arrange beds for up to six people, or a home for two people with a living room and home office. This versatile home can be configured to match your every need!

The garden house is delivered as a modular kit and can be easily assembled without prior construction experience. All wood, windows, doors, nails and screws are included in the package. Facade paint and roofing are not included. You can select from a range of materials including sheet metal, brick or roofing boards. If you would like to install shingles, we offer a ready-made installation kit as well. The same applies to the fitting of inner panels and insulation and you can tailor these and other features as you require.

”Simple to assemble. I built a house, just like that!”

"Great quality. Great service. When we received the delivery, the interior doors were missing, but the issue was easily solved.”

What could be improved?

"It's hard to think of anything negative, and any problems that arose were mostly solved over the phone. Maybe someone from the company could visit the site to solve any issues or give advice if there are any problems?”

"More detailed pictures for how to mount linings, mouldings etc. ”
