Whether rising to the highest room of the tallest tower in a Disney-esque castle, giving an admirer the chance to confess their love on an apartment building fire escape, or connecting a basement or attic room with a decorative period feature, there’s something unavoidably romantic about spiral staircases. But there’s more function behind these coiling forms than just their good looks.
One common-held theory is that spiral staircases were first installed in historic castles as vertical baffles, tiring out enemy infiltrators before they could make it to the top. This is why – it is said – many are set to turn clockwise on the ascent, so attackers have a smaller arc for swinging weapons (mostly held in right hands) than defenders making their descent.



Working within the restrictions of a limited carbon footprint can be one of the hardest – but also most rewarding – parts of a modern architect’s role. Whether to suit a large multinational corporation’s sustainability report, to achieve LEED status or similar for a commercial developer, or to build an eco-home for a climate-conscious private client – or even one who just wants to spend less on energy, it’s imperative to keep up-to-date with the latest carbon-neutral and low-carbon building practices and materials.
Whether looking at a project’s structural beginnings, its high-grade finishes, or thinking more holistically about its entire lifetime, there are huge gains to be made with sustainable substitutes and alternatives to traditional materials and techniques.

Kengo Kuma uses materials to connect with the local context and the users of his projects. The textures and elementary forms of constructive systems, materials, and products, are exhibited and used in favor of the architectural concept, giving value to the functions that will be carried out in each building.
From showcases made with ceramic tiles to the sifted light created by expanded metal panels, passing through an ethereal polyester coating, Kuma understands the material as an essential component that can make a difference in architecture from the design stages. Next, we present 21 projects where Kengo Kuma masterfully uses construction materials.
