Concrete really is very beautiful. And you can make amazing structures from it too – the screenshot below from a simple Google Images search is testament to this. Beautiful shapes, structural strength, and a neutral colour  which allows focus on form. However, it has serious environmental issues as it produces one tonne of CO2 for every tonne of manufactured cement – the binding ingredient in concrete – explained in detail by The Green Age. Unwanted concrete used to go straight to landfill but is now crushed for gravel or aggregates as the world tries to deal with our unsustainable levels of consumption and waste. Recycling concrete still requires transport and processing, which in turn use finite resources… and why the reuse of the old concrete piers from under our house make me so happy.

We have just raised our house. I call it the Tower in the Sky. The concrete piers that were left in the ground varied in size and appearance. Some have smooth edges and some rough. We hired a digger for the day and moved them round the block, forming garden beds and an edging to the new paving area. Around the paving area they have a second use: at 300mm high, these smooth concrete blocks make perfect resting spots. Have a seat.
