Design
The structure of the building will consists of a timber framework of Posts and Beams. Posts are vertical structures while Beams are horizontal structures and together they provide a rigid framework that supports the walls and floors.
This page will outline the the various construction Elements, followed by examples of possible building Configurations.

Frame Section
Frame Section
The Post and Beam construction method will allow the use of a modular design approach. This entails the use and placement of standard components which, when put together, will form the final shape and structure of the building.
The main standard component in this project is a "Frame Section" that is shown on the left. It consists of 2 or 3 posts which are held together by a series of cross beams. The lower cross beams will provide support for an elevated floor, the middle cross beams will provide support for the ceiling, and the top diagonal beams will provide support for the rafters and purlins which are part of the roof.
The posts and beam components of a "Frame Section" can be prefabricated off side and assembled onsite thereby minimizing the exposure to unfavourable work/weather conditions.
Multiple Frame Sections
Multiple Frame Sections
In Modular Design components can be repeated along the width or length of the structure till the specified exterior dimensions of the building have been met.
The picture on the left shows a series of 6 "Frame Sections" which are placed along the length of the building. Dependent on the budget and the size of the plot, this number can easily be changed without the need for an extensive re-design.
The posts of the "Frame Sections" are connected together with girt beams. Additional joists will provide floor and ceiling support.
Rafters & Purlins
Rafters & Purlins
The image on the left shows the rafters that run across the width of the building, and the purlins that run along the length of the building. There is no ridgebeam that extends along the entire length of the building. Instead the ridge consists of a number of girt beams, each one running between 2 adjacent King posts.
NB Purlins could be replaced with OSB sheathing if needed.
Roof Cover
Roof Cover
The roof consists of timber planks or OSB which in turn support the roof tiles. The image on the left shows slate roof tiles but alternative roof materials are being considered (e.g. metal, recycled material, vegetation).
NB The roof will cover a ventilated attic space. It is the attic floor that will hold all the "roof insulation" material.
Configurations
Configurations
The images below illustrate the various building configurations of this type of construction. The "Frame Sections" have been placed on a 3x3 meter grid. The width of the structure is 2 grid units wide and can be N grid units in length. NB In France one will need an architect when the total floor area exceeds 150 m2.
The final design concept will depend on the plot of land (e.g. size, topology), on local restrictions (e.g. colours, materials, maximum height), and on the costs per grid section.
Concept 1.0, 15x6 meters, Single story
Medium, 15 x 6 meters, single story
Long, 24 x 6 meters, single story
Small, 9 x 6 meters, single story
Small, 9x6 meters, double story
