William took a course on brick laying last week back in the UK, in preparation for the CEB construction adventures of Solar Village 2010 this year at Factor e Farm. Here is some documentation from his course:
In William’s words –
In preparation for building structures on the open source ecology farm, I thought it best to brush up my bricklaying skills with a week’s Introduction to Bricklaying course here in the UK. These sort of courses seem to be on offer in most cities and in my opinion give you more than enough experience to start building bungalows and small structures. This is because once the basics are mastered (which you can master in a few hours to be honest), it’s just like playing/building with what may best be described as giant Lego! In the video the structures built incorporate all the skills needed to build basic accommodations; walls, cavity walls, corners, inverted corners, spaces for windows or doors, lintels, pillars, chimneys and block work.
Our building concept for this year is evolving to double CEB brick walls, each 1 foot thick – with a 2.5 foot cavity. We have a hammer mill, and plan on chopping up large round hay bales to fill this cavity around the entire house. For the roof, we plan on a 1 foot deep cavity – the depth of the roof trusses – filled with the same chopped straw for insulation. If the bricks and hay are essentially free, we are talking of low-cost housing, and a super-insulated structure at that. The insulated cavity and its thermal performance is documented in a white paper on Chinese greenhouses. We are also considering a thermal insulation blanket as shown here.
Here’s the house plan from the top:
This .dxf drawing file is at the Open+Pario project management site, so you are free to download it and join the design process. Before we start building, we’d like to have working architectural detail drawings and visual models. If you can help, let us know. For more information, see the wiki page on the house design, and the wiki page on the masonry stove – which we will revisit this building season.
