Concrete and alternatives

Concrete is a wonderfully versatile material, which has been in use since Roman times and with it we can build amazing structures that would otherwise be impossible. Unfortunately it also carries a huge environmental cost, caused mostly in the cement binding used. Whilst gravel extraction is also an issue, for that there are some alternatives

Rain gardens

Rain gardens are a relatively new approach on how to deal with water in the environment. In the last 10-15 years, there has been a big rise in the use of SUDS (sustainable urban drainage systems), the practice of delaying the entry of rainwater into the drainage system by the use of swales, ditches and

The beauty of resilient planting design

The emergence of the idea of resilient planting is a response to a number of different pressures which all have one underlying cause – climate change. Whatever the cause – and I’ll get on to that later – I see it as the most exciting change to the way we design our gardens and landscapes.

Biomembranes for living buildings

NOTE: This article was first written in 2006, so some aspects have been updated to reflect current realities. Biomembranes is a term I’m borrowing from biology (the structure bounding a cell) to describe the outer skin of future self-sustaining buildings. I have stated elsewhere that I believe that for the built environment – and therefore

Biological filtration of ponds

The maintenance of ponds is the one thing that people seem to be the most uncertain about – it seems shrouded in myth and confusion. Some of this is basic ignorance of simple biological structures but this is enhanced, in my view, by the profession’s over-mechanised solutions to obtaining clear water. There is also a

The future of gardens in an age of climate change

This article was first published in 2007 and has been updated 2018. Future gardens will be an integral part of a living bio-system that is part house, part garden, an energy conserving and production environment.  It will also be a resource for water retention and cleansing, food production area, biomass and environmental haven. Above all,
