First floor extension atop existing garage.

Still not clear to me how far the side of your proposed extension would be from the window to your neighbours bedroom. You said 0.3m to the boundary and quoted a figure of 1.5m. Does that mean your neighbour's house is 1.2m from the boundary and your new brick wall would be 1.5m from this bedroom window?
p.s. with respect but it isn't a very attractive front elevation and poorly presented which can't help your case.

Yes, we are 0.3m from the boundary and the neighbours house is 1.2m from the boundary, meaning 1.5m between our extension and their window.
How would you make the front elevation more attractive? And what do you mean by poorly represented?
Thanks, Hayley

Can't explain in words on here how I would design the front elevation, or how I would draw it, apart from I would not render it like that .Presentation means how the drawing is presented - how good it looks ,for instance what is the cross hatching on the extension ,if that is meant to be brickwork you would show it as horizontal lines to represent brick coursing, you can just tell it hasn't been drawn by a professional architectural person. As far as the width of the extension goes, if you see it from your neighbour's point of view, would you want a brick wall built 1.5m from one of your bedroom windows, I wouldn't ? If it was a landing or a bathroom window it would be different. Trying to help really, what is the minimum internal width you would accept for the extension, is it just for a bedroom or a bedroom and an en suite , what is the floor layout ? Reducing the width by 1m would presumably leave you with an internal width of approx. 3m which would be the length of a bed plus 1m. If that was acceptable you could then start looking at the structural implications. You just need somebody designing it who knows what they are doing.

Thanks Leofric, we have reviewed dozens of planning applications (some drawn in biro!) submitted over the past year to our local council and followed the best one's drawn by architects. The cross hatching represents the new brickwork but I will take your advice and amend the plans. The plans are two pages full of existing and proposed projections and floor plans, if planning gets approved we will pay for building control plans to be drawn by an architect. The extension is to add 2 bedrooms and a small on-suite. Reducing the width would be possible however not preferred so hopefully it doesn't come to that. Wall to wall the distance would be 2.3m but I agree I'd prefer an open view.

You can tell the amateurs just by their hatching.

'You can tell the amateurs just by their hatching' Touch of sarcasm !

'Wall to wall the distance would be 2.3m' - does that mean you are amending the drawings to reduce the width of your extension by 800mm as you said previously the distance between your new wall and neighbour's window would be 1.5m ?
ps
'we have reviewed dozens of planning applications (some drawn in biro!) submitted over the past year to our local council and followed the best one's drawn by architects. ' - which local authority area are you in ?!

No, seriously. You can.

Hatching, together with line weights, line styles and shading are the giveaways.

The diyers do it because they see it on some of the "pro" drawings, but those drawings are complete ****e. If the designer can't even be bothered to hatch and present it properly, then what hope is there for the actual design or the precise detailing required when it comes to the technical drawings?

'Hatching, together with line weights, line styles and shading are the giveaways. etc, - absolutely right , couldn't agree more.
