Those of us living in the Northern Hemisphere may be mourning the end of summer, and with it the diminishing prospects of enjoying much warmth until next year. However, the Invisible Garden House, by Danish designer Simon Hjermind Jensen, may offer an opportunity to receive a regular dose of Vitamin D, even well into the colder seasons.

The Invisible Garden House was installed in the home of a Danish family who wished to extend their time spent outdoors into the fall. Essentially a large greenhouse comprising three interconnected domes, the structure is heated by the sun and ventilated naturally with adjustable holes.

The largest middle dome functions as a garden house with wooden floor, while the two smaller connecting domes are used to grow vegetables and flowers.

The domes measure 3.2 m (10.5 ft), 2.7 m (8.9 ft), and 2.4 m (7.9 ft) in height, and are constructed from polycarbonate (said to offer a degree of UV protection). All the necessary parts are designed on computer, then milled with a CNC router, and assembled with metal bolts.

Jensen reports that the project is easily reproduced in different shapes and sizes to suit, and that in addition to residential use, he reckons the Invisible Garden House practicable for public and semi-public use too – perhaps as urban gardening plots.

The total cost of this pilot project was €18,900 before tax (roughly $25,500), including assembly, but not including the wooden floor.

I think that is really neat. Hopefully if they do decide to produce them, the price would go down.


$25,000. That has to include the real estate! If not, I am not pleased to learn that transparent platinum is now available.

We have occasional strong winds that would rip this apart in an instant. Not strong enough.

A degree of UV protection ends Vitamin D production in Human skin, something we get anyway with drinking milk. In fact UV protection on the polycarbonate is essential to stop crystallization.


Nice concept i like this especially at evening the domes look beautiful...


I'm in a northern climate now and have seen many free standing structures which looked much sturdier than these crumble like tissue in winter winds. These don't look like they would take even a small winter gale.


I really do like the idea but I think like others that the price is way out of scope for some bits of transparent plastic stitched together with some more plastic

The idea has potential for other shapes as well but they have to come down to earth with some reasonable prices. For this price we can build a complete greenhouse with heating AND floor
