Joining two Apartments together in an Apartment Block

Need to find out if this coversion is feasible.

My Neighbour is on the 1st Floor of our Apartment Block in the corner. He has bought the Apartment directly below him on the ground floor of this Apartment Block. As this three Storey Building was built in 1960's ,do you think it is a good idea to join these two Apartments together using an Intertnal Staircase. What paper work is required for this Owner to Legalise this conversion and for Building Works to commence. My Apartment is next door to my Neighbour who wishes to do this conversion and also overlooks the Terrace of this Ground Floor Apartment below.

Many Thanks

You need to consult a architect..if you are proposing structural modifications.

Laws have changed recently; you need planning permission from the town hall to do anything.

Community and Local Council permits needed

It's a hard to thing to do right on your own. You'd better hire a professional

I've been in a similar situation, and I hope my advice helps. To determine the feasibility of this conversion, it's essential to consult with a professional architect or building engineer who can assess the structural integrity of the building and provide guidance on the feasibility of the conversion.

No it's not feasable at all.
