Not wishing to be a party pooper but are you sure you've got the dimensions/proportions right. Your plan makes the house look much taller and narrower than your photos. For instance the first floor window heads are tight under the roof soffit but the plan shows a considerable gap, likewise the gap between the first floor window sills and the lean-to porch roof.

Another trick that might be worth trying is to lower the roof eaves slightly. It makes the extension more subservient so you can get away with a smaller set back. It is also a bit easier on the eye.

I can see your point. I have used/borrowed some plans from over 10 years ago (done by an architect)

I will revisit the dimensions and proportions. Thank you.

Thanks so much for that. Would be happy to pay but might be against forum rules!

I managed to get something similar. ish

Why have you still got that little flat roof below the extension 1st floor window?
Just run the lean-to up to the wall - it will be easier for you.

Just hadn't got round to changing that bit. GIMP takes a bit of getting used to so I'm not the quickest.

Agree though that flat roof could be problematic.

Hi guys.

I am back with the attached. I have tried to angle the roof at 18.5 degrees.

Have also extended the roof on the garage to meet just under the window.

The proportions are now spot on as I have compared them to the recent drawings done for my previous planning application.

Am I any closer

Thanks again for everyone's help.

It would look so much better if the roof pitch on the extension was same pitch as house, don't worry about the pitch of the front part of garage roof that can be shallower. Also, very minor point, but your window casement marks are back to front, where the "V" joins should be the hinge side.

 

[A_Novice]

Thanks.

I have increased the pitch of the roof but not sure how this one would join to the actual wall if it meets like this.

 

[tony1851]

Have to agree with Wessex here - it will look odd if the roof pitches are different.
In your second drawing, the rear roof slope of the extension should ideally run in the same plane as the rear slope of the house roof, otherwise you will get a very
awkward detail at the rear eaves.
Also, on the side elevation, you will still get a short horizontal abutment where the new roof meets the existing gable, because your extension is more than twice as long as it is wide (remember that the hips should be at 45° in plan). You've got the two slopes coming together at a point. This is how it should be to simplify construction looking at the rear:
PS you've got the lean-to at the front correct

now.

Thanks for that sketch. Has really helped me.

I have come to these elevations now.

I'm not convinced on the side one yet as I'm not sure it accurately matches the detail on this part.

Submit either of those monstrosities to the council and they will be begging you to do a gabled roof instead.

Seriously, you need to work on showing how bad any sort of hip will actually look.

I understand what you are saying but the council will not allow a gable. The only scenario they would consider is if we came in 1m from the side boundary.

Has anyone else got any view on these drawings before I press the go button.

As the upper floor will be timber frame i was just going to go with tile hanging all the way around so that the timber frame can sit on the single skin block work of the garage (assuming foundations are adequate).

The tiles won't be really seen on the side. Going brick could complicate the build slightly?

Thanks

Hi guys,

Quick update in case anyone is interested.

Got planning approval for my application.

Thanks for your help with this.

Do you actually need pp to turn a hip into a gable? Did they put a restriction forbidding that?

 

[A_Novice]

There were no restrictions on the notice.

I'd be too scared to try putting a gable on ha ha
