Larch and Lime passivhauses

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 larch rain screen and [...]

Lancaster Cohousing

The Lancaster Cohousing group have recently purchased land near Halton on the River Lune near Lancaster. They are intending to build a number of Passivhauses and a communal building.

Kirk Park

Aberfeldy, October 2009

Demolitions

Building Control

Demolition of existing buildings is covered on the Planning Portal web site.

Basically the local authority Building Control require 6 weeks written notice (except for certain exempt buildings). They may then issue a counter notice with certain conditions attached. These are most likely to do with protecting neighbouring properties and the public. You [...]

Contractors

Make a contract!

Federation of Master Builders. These are a free download F220.  Domestic contract for minor building work for work up to the [...]

Suppliers

Where can I buy recycled plastic sheet made from kids wellies? At Smile Plastics of course

The world of suppliers to the building industry is a very mixed bag varying from the excellent to the appalling. When you are purchasing building materials it is of course good to go in with a positive attitude [...]

Getting started

As soon as you get on site you will probably want to organise some or most of the following:

health and safety

If you are having construction work done on your own home, or on the home of a family member, as a domestic client you do not have to notify the work to Health [...]

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

DPCs DPMs etc.

It is important to isolate all the dry inner surfaces of a building from any outer surfaces which might absorb water and be damp. The Building Regulations cover this subject here. While some outer surfaces are designed to be totally water resistant (such as roof coverings) many other areas can absorb [...]

Approved Documents (England)

The Approved Documents are ‘standard’ ways of getting Building Regulations approval. If you follow the principles and rules given in the documents you can be sure that they will be approved

The documents are as follows:

Part A (Structural safety) and see also the archived 1992 version which gives span tables for timber in floors, [...]

Hockerton Housing Project

The five earth sheltered houses. Image by WindandSun who provided the PV installation

The Hockerton Housing Project is the UK’s first (and almost only) earth sheltered housing development. It is a remarkable place, not only because of the five houses which are built into the side of a hill and are almost zero energy [...]

Thermal Mass

High thermal mass is generally seen as a useful quality in a building because it can be utilised to trap and save any spare heat which might turn up.

It can also do the same for coolth during hot weather. This quality is utilised in passive solar design, including the Passivhaus design standard. However [...]

Standards / regulations

Permissions and regulations

The two main permissions you will almost certainly require for building work are Planning Permission and Building Regulations consent.

Planning Permission deals with the overall issue of what kind of houses are permissible in which area. The planning officers are employed by the local council.

Building Regulations deal with whether the building [...]
