From the picture this looks like a very ordinary garden shed, but take a closer look and you will discover that it is far more than it appears. The shed is constructed in such a way that the main structure is in two halves that can be moved on runners to create a variety of different spaces. The shed is described in an article by Eleanor Gibson which I came across on the Dezeen website.

Sliding walls create various layouts inside Garden House by Caspar Schols
Timber and glass walls slide along runners to reveal or enclose this gabled garden shed in Eindhoven, designed and built by Caspar Schols as a hobby space for his mother.
Schols designed the pavilion with no formal architecture training after his mother asked for a pavilion that could be used for dinner parties with friends, theatre performances by her grandchildren, painting and meditating.
The Garden House sits on the edge of a pond in Schols’ parents’ garden. It is made almost entirely of douglas fir wood and at first glance looks like a typical garden shed.
But Schols separated the inner beam-and-glass structure from the outer wooden walls and metal roof and set them on runners. The walls part in the middle and can be wheeled inwards and outwards to create different layouts.
