Existing houses present a much greater challenge than new ones in terms of energy saving. However in terms of reusing building materials they often provide better opportunities.
Patrick and Fiona run a very pleasant bed and breakfast near Nelson, Caerphilly and their house has been the subject of much renovation and extension over the [...]
Larch house entrance
Although not self built, the two passivhauses at Ebbw Vale may be very relevant to many self builders. Built in 2010 as show houses mainly for the attention of housing associations, they are attractive and innovative while being relatively modest. The 3 bed Larch House is clad with a locally sourced [...]
straw board
Straw board is made from waste straw with usually about 2% MDI adhesive binder. In the past the reputation of straw board has suffered mainly due to people trying to skimp on the thickness, a bit like with hardboard. It can make for very economical internal surface linings with good thermal [...]
novolit magnesite / woodwool board
There are various types of cement/wood wool board combinations with Heraklith (which uses a magnesite cement) being one of the better known makes in the UK. Although the cement component is a cause of embodied energythe total amount of energy it takes to make a material (or a building). [...]

Home of Alexander and Vinny Burnett, Kashentroch is an elegant and spacious open plan timber frame house in a beautiful setting close to the Dee. The original part of the house (with the pitched roof on the right of the picture), built about 5 years ago, has recently had an addition of [...]
‘Under the Sun’, a Victorian terrace house in Birmingham is an outstanding example of bringing a fairly typical old building up to PassivhausSee more on the PassivhausSee more on the Passivhaus standard. The PassivHaus Institute has pioneered a standard for low energy buildings. It includes very low energy usage and ways of achieving this. The word is derived from the idea of buildings which are fundamentally low energy and passive solar heated rather than using extra gadgets to heat them.

It is becoming increasingly popular to incorporate elements of steel framework into timber frame and kit houses in order to achieve larger spans than are normally available with timber. This is often down to the preferences of the engineer doing the calculations rather than being an inherent necessity. Very often laminated timber would do [...]

In day to day terms, managing a building site is somewhere between a science and dealing with a madhouse full of demented jugglers, especially if you have never done it before. Partly this is because of the number of variables which can occur. Consider using a project manager, a self build consultant or a clerk [...]

Very often outbuildings happen as an afterthought and people go off and buy various kinds of prefabricated sheds, garages or summer houses. Usually these buildings are the worst possible in terms of green design because they tend to have travelled a long way and be made of materials which are high in embodied energythe [...]

The elements in a building are roughly divided into two parts
the envelope of the building like walls floors, doors etc. the services such as wiring and drainage.
Thinking of a house as a number of elements is the traditional way of organising the construction process and works well around the various trades involved. However [...]
The main types of walls
Regardless of the type of wall construction, all walls have certain functions to fulfil and certain challenges to contend with. From a green perspective, three of the most important aspects of walls are their insulation values, the embodied energythe total amount of energy it takes to make a material [...]

A very interesting terrace of three houses, on a curved road junction, has recently been completed in this Somerset village.
Some of the main features of the design are:

‘Energy use’ is usually associated with how much energy is used to construct a new building. However, this is only part of the story. Most buildings get altered and repaired and redecorated a considerable number of times during their lifetime and taken to an extreme, some houses are constantly having ‘makeovers’. This can vastly [...]

As a very rough rule of thumb, in average parts of the UK the cost of house building (excluding the land and excluding design fees) will vary between about £800/m² for a very simple design with no frills up to about £1,800 for a house with quite a high design standard and a high [...]
