Even if you take out the cupboard there is not enough room for an island and a table.

If you have to have the dining table in here then I would do this

If you are set on an island you could do this

Or this

Depending how much remodeling you would like to do, and how you would like to heat, one thought would be to remove the corner between the kitchen and rear sitting room. This would give you some hallway space and potential for a more open rear living space. This was may possibly have been the rear exterior wall at one stage so could mean more heavy duty work than you might want - making removing the cupboard and moving the doorway to create an area a more viable option.

Thanks both. Definitely wouldn’t want to knock the wall between the lounge and kitchen so does it look like them the only option is L shaped kitchen to accommodate a table & chairs? No option to have an island or breakfast bar plus a table & chairs?
