Charred wood forms the basis for 'Beetle's House' by Tokyo-based architect Terunobu Fujimori. The blackened surface of the small house – which, evoking a kind of fairy-tale-like, cottage-in-the-enchanted-woods aesthetic, sits on Giacometti-limb-like stilts – serves to unnerve and fascinate in equal measure. Entry, via a ladder up to the under side of the structure, is for the truly committed only. What narrative lies within the interior space of this outwardly poetically expressive structure? In contrast, fellow Japanese architect Sou Fujimoto's project lays everything bare. Made of Plexiglass, his fully transparent 'Inside/Outside Tree' geometric structure, which is located at the top of the stairs from the Grand Entrance, allows a single visitor to enter it, to inhabit it, while remaining visible by others. Here, the idea of retreat is subverted as the person in question is afforded no scopic refuge. 'The tree is not a tree, but a void of a tree,' says Fujimoto, underscoring the project's concern with the presence of absence.
