Low-impact development (UK)
The interplay between would-be developers and the UK planning authorities since the 1980s has led to a diversity of unique, locally adapted developments, often making use of natural, local and reclaimed materials in delivering highly affordable, low or zero carbon housing. These LIDs often strive to be self-sufficient in terms of waste management, energy, water and other needs.
High-profile UK LID sites include That Roundhouse (Pembrokeshire), the Hockerton Housing Project (Nottinghamshire), Simon Dale's so-called 'hobbit house' (Wales), Steve James's Straw House, as well as ecovillages such as Findhorn (Scotland), Lammas (Pembrokeshire), Landmatters (Devon) and Tinker's Bubble (Somerset).
Transition Homes, currently under development in Transition Town Totnes, Devon, is an attempt to scale-up and mainstream LID by providing around 25 low cost, low carbon homes designed along permaculture principles. Residents will be allocated from the local housing needs register. Similarly, LILAC is currently building a 'Low Impact Living Affordable Community' of 20 homes and a common house in Bramley, Leeds, which was visited by Kevin McCloud and Mark Prisk, Minister of State for Housing and Local Government.
BedZED (London) is another example of a larger scale LID, which was built in 2000–2002 and has 82 homes, however it is not as affordable as many of the above examples as it was partly designed to attract urban professionals.
Benefits of Low Impact Development 
LIDs have innovated and demonstrated sustainable solutions including low/zero carbon housing design, rainwater harvesting, renewable energy generation, waste minimisation and innovative forms of land management, including No/low-till farming, permaculture and agroforestry.
LID has also shown a capacity to enhance local biodiversity and public access to local space, and to produce traffic movements far below the national average. This has been attributed to lift-sharing, to residents' greater use of public transport, walking and cycling and to the integration of local land based employment with other household activities. As the Welsh Assembly Government has noted, such "...Development therefore is not just describing a physical development. It is describing a way of living differently where there is a symbiotic relationship between people and land, making a reduction in environmental impacts possible".
UK policy on Low Impact Development 
The extensive research interest in LID, backed up by the practical examples of the existing LIDs, has led to a growing number of planning policies in the UK designed to allow for LIDs. These include the Dartmoor National Park Authority's emerging plan on low impact dwellings in the countryside, the Pembrokeshire Low Impact Development Policy (Policy 52) and the Welsh Assembly Government’s One Planet Development policy which is outlined in Technical Advice Note 6 – Planning for Sustainable Rural Communities.
Barriers to the growth of Low-Impact Development 
Over the years, there have been various struggles with planning authorities over LID in the UK. Tony Wrench spent over a decade fighting the planning authorities until he was granted planning permission for That Roundhouse. As Lisa Lewinsohn points out in her MSc thesis on LID, Tony Wrench and his partner Jane Faith have been “enforced against, fined, refused planning permission several times” while Lammas has “probably spent about £50,000 on the application process.” Similarly, since 1986 Tir Penrhos Tsaf has tried several times to get planning permission and only succeeded in December 2006, twenty years after their first planning application was submitted.
The residents of Tir Penrhos Isaf consider:
"that current planning and building legislation represent some of the greatest obstacles to developing sustainable systems in Britain. The legislation favours those who already have land and property, actively encourages the squandering of resources and environmental degradation and actively discourages movements towards low impact, sustainable development."
Other LIDs, such as Quicken Wood, Framfield, have been told that they will not get planning permission to live permanently on the land after 10 years of battling with the local planning authorities.
Currently, several LIDs in the UK are engaged in ongoing planning struggles, including Pwll Broga in Glandŵr Pembrokeshire.
Development of the term 'Low-Impact Development' 
Low Impact Development (LID), in the UK sense of the term, was first coined by Simon Fairlie in 1996 to refer to “development that through its low impact either enhances or does not significantly diminish environmental quality”
Fairlie later wrote about the development of the term:
"In 1996, I started promoting the concept of 'Low Impact Development' in a book of that name, a book born out of the frustration of trying to obtain permission to live in a self-built, off-grid community in Somerset. Neither the term nor the concept was new. People have been living low impact lifestyles in low impact buildings for centuries; indeed until very recently the majority of people in the world lived that way. The book borrowed ideas from several other people, notably Tony Wrench, who was facing similar planning problems in Wales."
Since his original definition in 1996, Simon Fairlie has reworked it. He now prefers to define LID as ‘development which, by virtue of its low or benign environmental impact, may be allowed in locations where conventional development is not permitted.’
Fairlie explains his new definition:
"I prefer this revised definition because wrapped up in it is the main argument; that low impact buildings need not be bound by the restrictions necessary to protect the countryside from 'conventional' high impact development – a.k.a. suburban sprawl. There are two other principle arguments in favour of LID: (i) that some form of exception policy is necessary because conventional housing in a countryside protected from sprawl becomes too expensive for the people who work there; and (ii) soon we will all have to live more sustainable low impact lifestyles, so pioneers should be encouraged."
Others have expanded on the definition of LID. A study by the University of West England acknowledged that "LID is usually integrally connected with land management and as much as describing physical development, LID also describes a form of livelihood.” However, it also states that as LID is a “multi featured and intrinsically integrated form of development,” a simple definition cannot capture the meaning of LID and goes on to develop "a detailed themed definition with detailed criteria."
Dr Larch Maxey has also given a list of what he considers to be the main features of LID:
- locally adapted, diverse and unique
- based on renewable resources
- of an appropriate scale
- visually unobtrusive
- enhances biodiversity
- increases public access to open space
- generates little traffic
- linked to sustainable livelihoods
- co-ordinated by a management plan
