If you are going to do those changes that sounds good but you will still need a lounge and a conservatory is a bonus so you will still need to keep them. Adults will have their lounge and children will have theirs too. I don’t think you need to change either of them.

Please post the first floor as well. And how is the plot layout? The state the conservatory is in? Budget for extending or just internal reno?

That’s the first floor. Conservatory is in okay condition but eventually we will be wanting to change for a proper extension, not straight away though as need the internal doing first.

Looking at the plan, it’s unlikely you’ll be able to move the door to the garage to the bottom of the stairs as building regs require a little distance between stairs & doorways at the bottom for safety. It doesn’t look like there is room on yours. Also, I’d think the door in current location would be better to keep an eye on the children while you’re in the kitchen, etc?

Do you need all 4 bedrooms and does the house have an attic with considerable height?

Good idea to remove the wall between kitchen and reception. All rooms are not so big. I like an open concept. So I would think about removing wall kitchen-lounge as well.

i would knock the conservatory down as it landlocks somewhat your lounge. i would certainly make this lounge into a family room onto the garden and opening into your existing kitchen which for cost and existing services i'd leave where it is. you could also place double glass doors from the new family room,for flow, into what is the existing garage making that a bonus room for the children, with better borrowed light from the garden the front reception room i would leave as an escape valve room, not open plan. Children have an unfortunate habit of growing into teenagers and you will wish to have a den which could also house the computer etc to escape to & could act as a cosy homework room for now. if you are having an extension,why dont you leave the garage as it is making it into a fabulous utility with loo and washing machine etc. The money saved could then go towards a fabulous glazed extension one day and is a place to leave sports kit and detrius. have a big extra sink in there too. go online and look at how wonderful utility rooms can be. you are so lucky to have all that space !

Thanks for all your replies, definitely got a lot to think about.
The reason I want the kitchen wall knocking through is because it feels quite small so then would have a dining area at the bottom too.
Will be changing the conservatory eventually but budget probably won’t stretch that far to do it immediately. Might just have to leave it as it is for now?
Not sure I’m keen on having open plan lounge & kitchen - heard bad things about the smell of food & noises from washing machine etc.

Double doors into the kids room (garage) from the lounge sounds good! I wanted to relocate the door because that little bit of hallway seems so tiny and claustrophobic so this may just be the best solution I didn’t consider.

We had a utility in our old house & really liked it (was only a small one) would like it again but I think I would prefer more actual living space.
So many decisions !

Eventually hoping to do a loft conversion too if planning permission allows, thanks everyone

My house is open plan and with a good extractor (turned on at the same time the hob goes on) cooking fumes are not too bad. I do have a utility/boot though, would not want my washing machine in here.

When it comes to scetches, the sky is the limit. So here's my take on the house:

Since you want a more open feel kitchen dining, but not keen on opening all of it up, I removed one wall to create a spacious kitchen diner, the conservatory would be used as a lounge area, but the doors can keep in kitchen noises and fumes when needed. Moved the side entrance to create a utility. Kept the cozy front reception. Completely relocated the staircase and wc, while still leaving enough room for a study/playroom/guest.

By moving the stairs, one bedroom was sacrificed, but depending on your roof shape and loft options, a second staircase could go above (add a skylight as well, as the landing currently has no windows). Relocated the bathroom, so the master bedroom gains some space to move around the bed (it looked rather tight, was it not?). The bedroom on the top left has some extra width as well. Landing storage had to go, but if you'd like a new one can be created without hacking into more walls, as it's location in the scetch was open before.

Hope it may inspire.

Here an overlay of the first floor, for the changes I made:

i like the stairs being moved.

Can you alter stairs on my plan rinked?
