Could I knock down a wall between kitchen and living room?

What thickness is the wall? Is it brick or studs? Fan can be fitted almost anywhere :) Bart

If you are wanting to remove a wall in this flat to create a larger living space, you would first need to determine if the wall is load bearing, from your description it seems that it is a structural wall. Before demolition can commence, as well as seeking the freeholder's permission, you would also need to issue a Party Wall notices to all owners of flats either side of your flat, and above and below (unless of course yours is a ground floor property!) i.e all property owners that will be affected be the removal of this wall. A party wall surveyor would be the best professional to advise on all the notices that need to be served, the time frame this needs to happen in, and the procedure if any of your neighbours object to the proposed work. A structural engineer would also need to be consulted to specify a steel beam to support the opening created, there may be the need to incorporate denser engineering bricks into the parts of the wall where the ends where the new beam bears onto. A building control notice would need to be submitted to notify the building control department at the London Borough of Hammersmith & Fulham or to an independent building control organization such as the NHBC. This is to assess drawings and calculations submitted by the structural engineer and to inspect the works to ensure compliance with the building regulations. Only once all of this is done, a competent builder will know the sequence of requirements to remove the wall sections, prop the structure safely, and install the new beam.
