Removing a wall

man knocking a wall supporting beam down with a mallet If removing a wall, for whatever reason, it is first important to determine whether the wall is a supporting wall or a load bearing wall. The best way to be certain about this is to call in a contractor to look for you. If your wall to be removed is a load bearing wall you may want to rethink your project. Removing a load bearing wall is a difficult task and should only be undertaken by a professional or a very experienced DIYer.

Removing a load bearing wall

Load bearing wall framework If you have decided to undertake the task of removing a load bearing wall, the first factor to consider is how much weight the wall bears. All of its weight needs to be taken into account and this will include roofing beams, rafters etc. A structural engineer will be able to calculate this weight and how many props will be needed, or an online calculator can be used.

If removing a load bearing wall, a post, pillar or lintel will need to be inserted to take the weight from the wall.

This area should go beyond the length of the wall about 15.2cm (6″ approx) either side. The lintel can then be inserted and the masonry rebuilt.

Remember – Make sure you inform your local council of the intended work, as removing a wall may require a building control inspection first!
