Can a fairly new material be used in the same way as the conventional ones we have been building with for centuries? Would it be a viable option to replace, say, concrete, with an environmentally responsible alternative and still get the same results in terms of architectural performance? And how can a structure be intrinsically linked to its locale? It is questions like these that London-based designer Asif Khan set off to explore with his Wallpaper* Re-Made project, ‘Coral Reef ’, created in partnership with American cement industry innovator BioMason.
The North Carolina-based company, co-founded by CEO Ginger Krieg Dosier and her partner Michael Dosier, is revolutionary in its eld. It ‘grows’ sustainable cement by employing microorganisms, just as coral reefs are formed in marine environments. ‘A regate is mixed with our microorganisms, pressed into shape and fed an aqueous solution until hardened to specification,’ explains Krieg Dosier. ‘BioMason’s process enables materials to be formed in ambient temperatures by replacing the curing process with the formation of biologically controlled structural cement.’ The company is also researching marine biocement with the ability to self-repair.
The idea for ‘Coral Reef ’ was born of one of Khan’s ongoing projects in the UAE – the new Museum of Manuscripts in Sharjah. The structure is currently under construction (with a view to completion in 2021), and its surface is made out of many small stone elements, referencing traditional local coral-stone buildings and the geometry of Arish, the region’s palm-leaf architecture. ‘When we started working with BioMason, I wondered if we could recreate an element of our building from its biocement, and I wanted that product to use Sharjah’s sand as its a regate material – a resource that is plentiful,’ says Khan. ‘It’s an experiment, but the idea of making a structure from what we found on site is very simple and poetic. We decided to create a prototype section of external wall as our Re-Made project to test this possibility.’
Creating the structure with Sharjah sand is not as straightforward as it may seem, even with BioMason’s strong, existing ties with this part of the world. ‘We first used the sands and indigenous a regates in Sharjah in 2009 when we created the technology,’ says Krieg Dosier. ‘We will seek to bring this technology full circle by using Sharjah a regates to produce our BioLith tile product [the company’s main product for commercial and residential applications] as a building façade material.’ The collaborators agree that a lot of research and strength testing will be needed to ensure the end product’s workability.
