How do I bathroom / kitchen / extension? etc.

Not sure how important it is to you but where will the TV go in that lounge area? Can't tell scale but I imagine there's nowhere to wall mount with that glass on either side which means a corner unit - a bit 90s.
Yeah I wondered that. We only have one TV at the moment which is in the living room. We do have a smaller one that we could put in the extension but we'll probably just balance it on some accumulated crap, we're not really TV on wall people.

I like the roof design..
Thanks, I guess it's the only interesting thing about it. One of my concerns is we've just raised the pitch of the lean roof quite substantially so we'd need to work out a good way for the extension roof to join this nicely as it won't be a continuous form.

Thats going to be lovely!
Hopefully!
Wouldn't have the peak of the roofs in the centre make the whole extension feel a little bit higher with more headroom?
Yeah I guess so, but then you'd lose the form? You think it looks claustrophobic on the iso view?

Nice! Are you dead set on the dormer being en suite? Could the door be on the landing to make it a stand alone shower room and toilet? IE two doors between someone night pooping etc.
Not dead set, GF has brought up the seperate room / night pooping thing so that'd need looking at for sure.

Got a proposed location for a boiler and flue?
The very north west corner of the lean to on the ground floor. It's being fitted on Monday hence the need to raise the lean to roof to fit the pipework.

My personal opinion is to infill the side and gable end the extension. This will make the space much less segregated and clean the roof design.
Don't really understand the infill the side bit.

*will add significant cost.
Boo.

Hah - we used to live in Blenheim Park.
Where's that?!

I like it - the double pitched roof is nice, is there a reason for it or just because?
Just because i guess. The 1st floor windows are pretty low to the ground which I think potential designs.

Bench seating internal and external of the picture window could be nice (it’s what we’re doing) and might help with connection
Yep, just picked up a lovely 3m church pew from a local church last week

How do those corner doors work - in summer will it be easy to get in and out and the house/decking feel connected?
Not sure, GF not convinced and wants sliding french doors.

Are there windows all along the side of the utility? Seems like a lot of nice light to be giving that space over the main living space
Good point, we're having 2 velux fitted in the utility room so maybe a window centred on that through to the kitchen.

be interesting to know how the rear extension roof(s) drain.
Yep, I wondered that. A friend round the corner is having bad problems with leaking on his new rooflight and that's a straightforward one.

I don't know what your objectives are for the top floor room, but it might be worth exploring exactly how much space remains in it once there is a king sized bed in it, and whether there are options for increasing the size. I'm slightly confused by the diagrams how the proposed design accommodates the chimneys - does it envelop them or not?
Yeah it is a bit confusing, I'm not too sure why he's drawn it like that. It's a really big loft though so I don't know why it looks so small in the drawings. Think we're gonna have to lose a chimney or two, just internally though.

Also as this looks like your stage 1 - make sure they have a really clear idea of your costs and that any designs you go forward with won’t suffer endless reduction due to requiring value engineering.
He's aware it's a very tight budget. We're possibly gonna have to go first fix only and I'll have to do the rest over the coming years. Fun.

Nice, I like the matched slope of the roofs and that angle will give more of an open view while providing a bit more privacy for and from the neighbours.
Yep, it'll get the sun and there's already quite a high wall next to the neighbours so they should hopefully be used to it.

I'm thinking we might lose the proposed new living room doors, as we need space for a shit load of records and a wide turntable set up. Not sure what benefit they have apart from providing a quicker route to the living room for TV dinners which I hope we'll do less often anyway.

Phew.
