Invisible Garden House Can Bring Greenhouses to Urban Areas

invisible garden house photoDanish architect Simon Hjermind Jensen has created an Invisible Garden House, three small, semi-portable garden pods that are arranged in a cluster. They are designed to create a micro-climate for plant growth and recreational use in the northern temperate zone.

The domes were built in a private garden at a single-family home north of Copenhagen, Denmark. They cover small garden beds and patio spaces heated by the sun. The largest dome in the center is a garden house with a wooden floor. The other two, smaller domes are greenhouses used for growing vegetables and ornamental flowers.

The 4-mm thick shells and frames of the domes are made of UV-protected polycarbonate, which is durable and high impact-resistant. The parts were drawn on a computer and milled on a CNC router. They are held together by metal bolts. The shells are dug below the frost line to support the domes.

The inside temperature is controlled by a natural ventilation system. Latches in the top can be opened to allow heat to escape in the summer or locked to keep heat inside during the winter.

Jensen’s previous work arranged modular structures into complex shapes to promote social interaction. He considers portable structures more responsive than traditional ones, especially in cities.

The architect, who runs SHJWORKS in Copenhagen, is working on finding applications for his garden houses in public spaces and marketing the system so that people can build their own greenhouses. He envisions them being used as public urban spaces or for urban gardening on a building with a flat roof.
