Not getting ratty - just annoying when people who don’t know what they’re talking about post rubbish!
The only thing wrong with the single block wall between the garage and house is heat loss - FR is not an issue through a solid block wall.
A much better response to the site - however you’d need to see how your accommodation fits in.
Put the bins to the back - have a couple of parking spaces to the front and be able to turn on the site.
FF.
No need for a cavity wall to run front to back through the house.
Need a bigger hot press.
Look at the section in relation to the roof and how it works over the front bay window - should be ok.
Cavity walls look a wee bit narrow - looking at 170mm cavity nowadays for good thermal efficiency.
Other than the above it looks ok.
GF.
Need to thermally separate the garage - the cavity wall needs to completely enclose the garage including the door access.
You don’t need a step at the door - ideally yes - but other options are available.
Need at least the width of the staircase at the bottom of the staircase.
Garage front piers are too short.
Steel work across the back is a bit of a design flaw.
GF WC is not wide enough.
Other than the above it should work.
Good idea….I think you might need one for each bedroom plus another couple just in case there are any visitors to the house…..oh and don’t forget a space or two for disabled drivers and electric vehicles……FFS!
Maybe not both doors on either side wide open, but you'd be able to manoeuvre a car in that space and get the driver's door open for exit.
It will be as tight as a gnat’s chuff - so tight that it becomes almost unusable.
Then why have you employed an “architect” to design your house and then asked a bunch of strangers to help you re-design the windows. It’s like having a dog and barking yourself.
I’m presuming your SE has two things on his or her mind:
1. The foundation is asymmetrically loaded.
2. He doesn’t want to get sued if shit hits the fan.
I think you don’t like the way the cladding interacts with the brick - and I agree. It needs rationalising. Also you’re using too many different materials-it’s becoming too fussy for want of a better word. Plus the garage looks tacked on the end-it’s needs to be more integrated into the overall design. Watch this space!
