1 room house of 30m² in London

I live in my home with my two daughters and grandson who are living here temporarily. We are a very friendly family and have been welcoming visitors to our home for years. I also have two sons who live in separate parts of London. We have all transport and amenities as we live in the town centre. There is a small garden which needs tlc but have to wait until spring to attend to it. We live in a cul de sac with parking.
