ETC

Just go with a pitched roof and a flat roof with a parapet - it will look nicer.

Why have a pitched main section and an elongated flatish section?

It’s not expensive if they save you from c**king everything up. A good architect with experience in conservation/listed building work will save you money in the long run and from those charlatans who will try and sell you quick fix solutions to a plethora of problems that can be encountered when renovating a listed building.

I’ve your drawings in my “to do” pile. I’ll be in touch.

Yes of course. Please PM me.

That’s what I love about this forum - people prepared to spend vast amounts of money on a house but not prepared to appoint appropriate professionals to deliver the project. I have a serious question for you - if you spent £450,000 on a car would you let an inexperienced and unqualified apprentice service your car?

Read the BBA Certificate for the underlay. It will say if you need roof ventilation and under what circumstances you can omit eaves and or ridge ventilation. Some underlays can be installed without roof ventilation subject to a well sealed ceiling being installed. On reflection I think Tyvec might be one of those that do allow an unvented roof but I think down lighters are not allowed. Check it out.

Er…….ask your engineer. Don’t make it up yourself.

Get rid of that shit cement strap pointing for a start otherwise you’ll end up with spalled brickwork.

With a lot less imagination too!

Central living space - bedrooms to each end.

A couple of sketches I’ve done in the past.

There’s nothing wrong with your concept - take a look at contemporary Scottish vernacular architecture - here in Ireland the development of the home started off in a linear fashion - a central living space - much like what you have with bedrooms off the room and a long front corridor. Leave it with me. I’ll sketch a few ideas.

So much great Scottish architecture out there.
