suggestions on how to layout my new house!

[Minster2012]

We are in the process of buying a new house, 1950s with a view to bringing it up to date, extending, changing layout & making it forever home.

FYI the garden is at the back & to the kitchen side is the nicest bit

Problems:
-It's 5 bed but 5th bedroom small
-The "garden room" is horrible so need to change that, most likely with kitchen /diner.

• they have added a lobby likely because of the stupid 'u' shaped walk you have to do with shopping from front door to kitchen, so change to a door from hall??
• utility too small, we need bigger ideally as a boot room with access from back door & room for dogs to sleep in big crate
• ideally off or in utility a downstairs shower room
• the en-suite is terrible & that's not the nice side of the garden view so they use (& we would use) bedroom 2 as master
• we'd like a playroom (see below)
• the back is north facing which is where a lot of the garden is, doubtful to go outwards from the front

My only thoughts so far...

• use bedroom 2 as master, make bathroom next door en-suite? (Changing bed 5 to main bathroom) so how to get 5th bedroom back?
• would still like another en-suite in bedroom 1 so can this be gained (& 5th bedroom by a 2 storey extension on that side?)
• 2 storey extension behind reception room with large windows top & bottom (which means bottom bit can't be utility) 🙄
• knock through from kitchen to sitting room only leaving the open fire (adding in log burner in the middle somehow) to have large kitchen /diner/garden room open plan into playroom
• enclose an area next to sitting room to create a utility /boot room with back door then walking through into hall? With shower room? Probably too small

My mind 🤯
We know it can be stunning but struggling to think how we can meet what we want 🤪not sure how big an extension we can have yet, most likely not extending the back so it forms a straight line from the sitting room IYSWIM.

Any thoughts appreciated
TIA

Something like this maybe?

@YellowFish12 that looks good, thank you! I shall def take that with me & see how big it actually makes the rooms. We were thinking a 2 storey extension, do you have any thoughts on that? Top or bottom? But it might be you are right & a top storey extension isn't necessary

Can you go into the loft rather than a 2 story extension? Downstairs looks quite big already?

I would probably move in and live with it for at least 6 months. The ground floor does look a bit odd and disconnected as a layout, but it depends which walls are load bearing how easy it would be to reconfigure completely, or just adjust.
Adding a 2 storey extension would give you plenty of space, but doesn't sort out the awkward corners. Having an idea which ways you move through the house, will mean you know which bits need to be rearranged.

@YellowFish12 there is a loft, so possibly, though that's great storage space & DH is 6'6 so struggles with eaves & feeling claustrophobic, the downstairs is big enough it's just the utility room really isn't. Its smaller than our current one which we would like to address (& put the dogs in there as opposed to our hall like we do now)

@DamnYouAutoCatRectal we def are going to move in & see I'm just keen to get playing & potentially give ideas to an architect, & the layout downstairs just doesn't work!

Has the house already been extended? Which may restrict what you can further extend by.

@LizzieMacQueen it's been extended to its maximum width, (is it 50% bigger?) I believe you can then extend backwards still? I may be wrong though

@LizzieMacQueen we are happy to keep the width don't need wider, but ideally would go more at the back
