My house is a 3 bed semi detached, coming up for 25 years old. We converted the garage to a playroom and downstairs loo. The bedrooms are all a good size. The downstairs has archways from the living room to the dining room and then the kitchen. This has suited us with the children young as we're all together and I can keep an eye on them easily.
The kitchen and dining room are very small. I'm starting to think about extending out from the kitchen and dining room, knocking down the separating wall, and close up the arch from the living room to dining room with double doors. This would leave us with a square living room but a nice sized open kitchen diner. One of the reasons behind this is thinking about 4 adult sized people trying to use this small space in the future. I've got plenty of time before this happens but I want to know from anyone who has done similar - are you glad you did it? How much did it cost? Any tips?
I've considered moving but the leap to the next sized properties seems to cost more than extending.
