Practical Home Design
Ever practical, the Swedes have evolved a construction system that is based on a very simple grid principle. By designing the floor layout on this grid you benefit from great efficiencies in manufacturing and construction time on site.
But this principle does not mean that your design flair need be restricted. Most building components nowadays are made to metric dimensions, most commonly wall and ceiling boards, plywood and flooring, windows and doors.
The principle of our grid is to accommodate these standard components efficiently by effectively “dropping them” into our grid. We base our designs on gross internal floor area dimensions in modules of 300, 600 and 1200mm. For efficiency most house plans are formed with a collection of interconnecting rectangles but each of these rectangles can easily follow the same grid principle. In practical terms you might choose to start with a rectangular floor plan measuring say 9.6m by 7.2m internally i.e. 8 modules of 1200mm by 6 modules. It’s a good principle to try to stick with internal building lengths on the 1200 or 600 grid but internal spans usually require more flexibility. When planning the internal layout don’t forget to allow for the thickness of internal walls (generally 100mm) as they can account for 5% of the available floor area and of course don’t forget to design in lots of practical movement and storage space.
With our construction system you can opt to have ceilings at any height, however it makes sense to consider two standard wallboard heights of 2.4m or 2.7m (these fit nicely on our trucks). We incorporate a continuous beam along the head of our external wall elements allowing window and door positioning wherever your design dictates.
Our windows and doors come in a complete range of metric sizes with standard external door width of 1.000m including frame and windows typically 1.000m wide by 1,200mm tall and variable in 100mm increments.
Typical roof pitches are 22.5, 27, 35, 38 and 45 degrees being the most popular Ideally the roof overhang at the eaves will be at least 400mm to shelter the walls and windows from the worst of the weather in winter and the overhead sun in summer. This feature prevents excessive solar gain in summer yet allows plenty of daylight from the low winter sun.
