Timber frame

overview

‘Timber frame’ has several meanings:

Platform frame where walls are assembled on site into storey[for the purposes of part B (fire) of the Approved Documents to the Building Regulations] this means a. any gallery[for the purposes of part B of the Approved Documents] – A raised area or platform around the sides or [...]

Insulation and wall thickness

With increasing levels of insulation, the total thickness of a wall becomes an issue in relation to land values, especially in densely built urban areas where space is restricted. The total footprint of the external walls of a house can easily be around 15 – 20% of the ground floor area and this becomes significant.

Space heating

It is reckoned that in the UK, heating houses accounts for nearly 50% of the total energy use. Poor heating can render parts of dwellings virtually unusable, partly through discomfort due to cold and drafts and partly through the damage caused to contents through condensation, dampness, mould growth, etc. effectively reducing the house size [...]

Main structure

Method of construction

How you design and build the structural elements of a house depends on many factors. Although not in particular order, because they can all dynamically affect each other, the first few do tend to set the scene, especially regarding what the planners will allow.

Traditional considerations :

Planning conditions

Planners [...]

Air tightness

‘Build tight – ventilate right’ Building Regulations

The subject of ventilation is fully incorporated into the Building RegulationsThese are the legal regulations which govern how a house is constructed. (not to be confused with Planning Permission which is about whether you are allowed to build the house at all or what it might look like) [...]

Larch and Lime passivhauses

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 [...]

‘Under the Sun’, Birmingham

Bringing existing houses up to a high standard of energy efficiency is a much greater challenge than with new ones.

This particular example of eco renovation is outstanding because of the way it will achieve a net zero carbon rating while at the same time reaching CSH Code for Sustainable Homes. A standard for [...]

The Tree House

The Tree House in Clapham, London is a recently completed and very elegant example of a self built detached house. It has, on occasion, been open to the public as part of the London Open House programme. Situated on a small urban plot of land dominated by a large sycamore tree it has [...]

Passivhaus at Denby Dale

the front of the house with double storey[for the purposes of part B (fire) of the Approved Documents to the Building Regulations] this means a. any gallery[for the purposes of part B of the Approved Documents] – A raised area or platform around the sides or at the back of a room which provides [...]

SIPs

Structural insulated panels have been around for decades but have only recently achieved the interest they deserve. They are large factory made panels including walls floors and roofs and are fixed together on site. A lot of the kit houses in the UK are based on SIPs.

Several factors distinguish them from traditional building [...]

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 [...]

Part L and SAP (England)

The Building Regulations, part L, is the section which covers energy conservation for new buildings (with part L1A covering new buildings and part L1B covering existing ones)

At present there is a period of transition which is well explained in an NHBCThe National House-Building Council describes itself as being “the leading warranty and insurance provider [...]

Chewton Mendip

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:

Very high insulation levels provided by insulating concrete forms (ICF) with added exterior face insulation Structural insulated panel (SIP) roofs Eco-slab ground floors and upper [...]

Self Build Central

Self build eco houses in the Field of Dreams, Findhorn FoundationThe Findhorn Foundation is a large community near Inverness. There is a strong emphasis on sustainable building and living.

Over the last decade or so the green building movement in the UK has gone from being fringe to mainstream.

Architects, builders and suppliers are [...]

Ventilation

How you ventilate a house depends very much on the level of energy efficiency you are aiming for. At the lower end the Building RegulationsThese are the legal regulations which govern how a house is constructed. (not to be confused with Planning Permission which is about whether you are allowed to build the house [...]

Energy Harvesting

There are several methods of harvesting energy for a house but non of them are as important as providing excellent levels of insulation, air tightness and energy efficient appliances in the first place. Witness to this fact is the design of the PassivhausSee more on the Passivhaus standard. The PassivHaus Institute has pioneered a [...]

Green Design

October 2011

Background

If you are thinking of building a green building then it pays to be aware of where this whole process is going

Eco-house design is a fairly recent development which started getting off the ground in the UK during the mid 1990s.

Passive Solar Design

Not to be confused with solar panels or 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 [...]
