CORAL – Loft London Farm Tower

The design concept „CORAL“ tries to find an optimized way for urban vertical farming. The sheer amount of technological, agricultural and structural possibilities should be considered well and have to fit into the local environment of the projects site.

„CORAL“ tries to connect to London on different levels. A first analysis shows that it is possible to find a theme for the design covering some of the problems the city is struggeling with. The Thames River next to the projects site is one of the most polluted rivers in europe. In times of heavy rainfall sewage is led into the river uncleaned, because the sewers cannot handle them.

Londons water network is very leaky and old too. So it seems logical that a design for an agricultural farming tower which will consume a lot of water should face and be able to handly these problems.

The concept of „CORAL“ suggest a cluster of several towers which are highly optimized by a parametric design. This optimization would cover the most important conditions like light, wind and temperature to grow the towers individually.


The towers themselves are grounded in a small lake with water plants like reed. Water from the Thames River will be pumped through the ground into it. The natural process of phyto purification is able to clean the water. The water then can be used for farming purposes or it can be stored in the towers for further usage. An idea would be to use it as kinetic storage for electrical power at night, when energy is produced by wind turbines but cannot be consumed immediately. As the consumptions reaches peak levels at day, water can be dumped into the Thames and electric power is produced through small water turbines.


The towers a highly automated. The process of vertical farming is very complicated and expensive, so there is no option. An infrastructure of robotic farming machines will take care of the growth of vegetables and fruits. The same infrastructure could be used to build and expand the towers on demand. The optimization process could be held up even after the project has been build. It could react to changing economical and ecological requirements.

The materials used for the CORAL-towers are chosen well. Wood-plastic-compounds and recycled concrete are already available. Nano-Carbon-Fibres could replace the usage of steel.


In the image above one can see the parametric base shape used for generating the CORAL-towers. The shape can be changed only by variation of three parameters which lead the shape to either degenerate or move closer to its neighbours in the triangular grid.
