First floor cavity wall construction on top pf the ground floors existing thinner wallx
Anonymous user 09/03/2024 - 3.21 PM
Hello There We are adding a first-floor bedroom on the side of the property. Ground floor walls are 1930’ 250mm walls with an empty cavity between the two brick skins. The new first-floor wall will be a 302mm brick/block standard cavity wall. The outer face of the new wall to be aligned flush with the existing ground floor brick face. This means inner blockwork will be about 50mm projecting out from the existing inner brickwork. How to support the bottom of the first-floor blockwork? Thank you so much in advance?
Are you a tradesperson and able to answer this question?

Personally I would go timber frame. In this case I would also advise using an architect rather than letting a builder decide! It could save you a lot of drama.

The new walls can simple be build on the existing structure (100mm outer leaf with 50mm filled cavity and a 100mm inner leaf) then it is a simple matter of the correct insulation thickness and plasterboard to be bonded to to inner face.
Many jobs have been done to this spec with B.C. approval
