If anyone can help me with some pointers then it would be great!

Thanks One Plan for your recommendation. Would it be good to go for Herringbone pattern in hallway and in the open plan vinyl straight planks and then matching tile in the decking area. We have shortlisted karndean vinyl for open plan (Von Gogh Distressed Oak) althought not sure. Also what type of anti-slip material should I go for if I had to matching wooden look vinyl ?

SJ , With due respect to your personal choices, for a family of 6 this is certainly looking over the top. I would suggest you to cut down the TV units to 2 or 3. You may not need 25 seats for a closely knit family it looks like we are trying to create silos in the home where everyone just sticks to their rooms, with separate baths, accent chairs, study and TV units. I would recommend you to convert the NE bedroom's bath as a common one with entrance from living. You can then do away with powder room. SE bath has a wardrobe inside the bath, I wonder why would you need that. It may not be a ideal placement. Thanks, Nitin CORNERSTONE DESIGNS Bangalore.

This is possible. Black pen shows the placement of dining table, red line shows the partition at the entrance to avoid the direct vision of dining area from the entrance, red cross shows the kitchen entry which will be shifted from the present entry.
