I was never a conservatory lover and it would certainly wouldn't have worked on a sunkern, NW facing garden at our previous house, but our current one has a south facing double sized one. Generally it is useful from March to October, but even at this time of the year, it's good for a large Christmas tree, and the kids do go in to play where there's more space. In most of the warmer months it can be ventilated well enough without cooking. Opening the kitchen and lounge doors lets lots of heat through to the rest of the house.
I like a kitchen/ diner, it's easier for serving dinner, and it is more sociable. The neighbours kept the original seperate rooms and both feel tight in comparison. The lounge needs to be seperate though. Much more cosy and relaxing.
Our utility room was clearly designed by a man with poor domestic skills. I'm grateful to have one, but it is too tight and easy to get tangled with the laundry basket, washer door and back door!
An en-suite is good on the master room, but I'm not fussed about additional en-suites, particularly for children's rooms. I'd rather have a bigger main bathroom.
I'm not a fan of the monotonous grey fashions, minimalism or words used as decoration. To me, the most homely homes are a little bit eclectic as people gradually buy things they love.
