I'm looking for advice designing my open plan downstairs. I want to incorporate a kitchen dinning and living area with narrow and limited space.

The "L' shape which extends further on the right will give you marginally more light into it - but this depends on the design of the roof and glazing - which is vitally important to the end result. I would consider putting pocket doors from the lounge into the kitchen (keeping the size as is) to allow the afternoon sun to be seen from the kitchen. This space might be a better option for the playroom - depending on the age of your children etc. I would put kitchen on the right hand side. Could you put a door from hall into the bike store so you don't have to go through the kitchen? Consolation prize for this orientation is that the back right hand side of your rear garden will hold the Summer evening sun the longest - so thats where to put the BBQ!

Hoping to knock the wall between the kitchen and the sitting room . Want an open plan kitchen dining room and sitting room .. Also struggling to figure out what to do with three doors utility , kitchen and hallway door? For a renovation .

I think introducing an angled wall will not give you anything other than something a bit different. We have this in our house and it is difficult re positioning of furniture etc. You are also limiting what you can do it the kitchen, ie removing a wall of presses or increasing the cost of having custom made to fit! You have lots of space so I would leave that as it is. I dont know if you have kids, but think about how you will use this open plan space as they get older and you need more privacy! In relation to upstairs I like the idea of the Jack and jill but prefer the layout of the master bedrooms in the original. That is a really big dressing room compared to the size of the bedroom, but if this is what you wanted go for it!
