Mortise and Tenon is one of the most traditional and strongest joint in history. However, this
joinery is not widely used in the industry as it is technically difficult and requires a lot of time to
construct. However, we found that LVL panels are actually very suitable for this joint as it is
laminated timber, therefore, we are proposing a solution to ease the production of these joints.
Generally, the LVL panels are arranged accordingly before pre-pressing to create the joints.
If this joint is successfully used, we are confident that timber buildings are able to achieve to
another level. Throughout the whole building, we focus on using this joint including the fitting of the
new building to the existing structure.
As we are building in a high altitude, joineries of the building are important. This is because
the building will face a harsher environment comparing to medium size buildings. By using Mortise
and Tenon joint, we are able to reduce the wood usage by strengthening the joint of the building.
Furthermore, the timber beams of the building are able to span longer than the typical timber
Moreover, the exclusiveness of our plugged in units reduces the usage of bolts and screws
during construction, as well as allowing the residents to change their apartment layout freely. Our
units slab are all placed in an angle where each unit façade is facing the exterior. This is to prevent
privacy issues after extension. Additionally, it allows the timber façades to carry out carbon
sequestration in a bigger scale.
In order to reduce the carbon footprint of the building, we proposed a few design solutions.
Firstly, the units are custom made and factory prefabricated. Secondly, we reduced the surface area
of floor slabs by allowing 2 storeys to share a common area – the ramp.
In summary, by using this joint we intend to stretch the boundaries of conventional timber
