BUILDING ENVELOPE
to the local geography and building style. As a general rule, more exposed locations would have overhanging copings, sills and roof eaves to minimise the saturation of brickwork, due to wind- driven rain. In severely exposed conditions it is a requirement to use overhanging details to ensure durability and prevent water penetration.
that could give you inspiration on the design of your self-build brickwork project. There are also a number of short design guides that introduce details, such as ‘hit and miss’ and textured brickwork. The detailed design for brickwork is a
large subject – too much to cover in the space we have here. Historically, the detailed design would have varied due
WORKMANSHIP The success of brickwork is very dependent on the quality of workmanship provided by the bricklayer. Once brickwork is built there is very little appetite to take it down, so it is essential that it is built correctly the first time. Due to the nature of brickwork being a site-based trade, it can be challenging to manage expectations around the appearance of the finished work. For larger projects, the single most important step is to build a sample panel of brickwork so that all parties can agree to the quality of finish. The sample panel should be at least 1 m2
(60 bricks) and
preferably in a location where it can be kept for the duration of the project. If a sample panel is not possible then an area of brickwork should be agreed as the quality benchmark.
Brick is a natural material, which can mean there is a small variation from
The design of brickwork can influence the durability and performance of the finished building, can also affect how it will weather
one pallet to the next. To minimise the possibility of patchy brickwork therefore, bricks should be blended from a minimum of three packs. For more detail on this and a number of other workmanship tips, please see the BDA document ‘Good site practice and workmanship.’

THE BULMER BRICK & TILE COMPANY LTD
The Brickfields Bulmer Sudbury Suffolk CO10 7EF
Bulmer bricks are made from the finest London Clays, dug from our seams almost continually since Tudor times. All Bulmer bricks are hand made, using traditional methods of making, drying and are fired in a down draught kiln. This helps to give the distinctive finish that blends so well with the originals. The process takes time – something to consider at the project planning stage. We work on large projects for the National Trust, English Heritage and Historic Royal Palaces, but are just as proud of some of the small private work undertaken by individuals.
