Patrick and Fiona’s house

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 and Lime passivhauses

StrawBoard

Retrofit

‘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 Passivhaus standard.

Steel frame

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 [...]

Managing self build

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 [...]

Outbuildings / garages

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 [...]

Construction

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 [...]

Walls

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 [...]

Alterations & Fashion

‘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 [...]
