Thanks for your reply. Just to clarify, we’ve already moved in, which is why I’m asking for advice on the layout.
The current dining room is not only used as a dining space, but it’s also the throughfare to the old patio doors and kitchen. The kitchen is quite far from the living room, and the split level difference between the front and back of the house only makes the distance feel worse.
There’s already a large opening (around 2m x 2.2m?) between the kitchen and dining room from the previous extension. The kitchen is in need of replacement as there are no proper fitted units, and all the services (boiler, water, electrics, etc.) are closer to the stairs than the extension, so it seems more practical to make changes in that area.
Regarding losing a reception room, I’m not sure how that would apply in our case. If we move the kitchen into the current dining room, we would still have the living room as a reception, so not losing a space there.
We could look into moving part of the partition wall between the front bedroom and the bathroom to widen it — possibly the middle 2 meters of the current bathroom. However, the original part of the house has a supporting wall only about 800mm from the end of the bathroom, so shifting it would likely involve a fair amount of structural work, as it supports the wall plate. We did think of trying to shoe in a bath into a indent into the front bedroom by moving that partition.
Hope this clears things up a bit, and I really appreciate the input!
