The stairs going up should also be reasonably comfortable. How much does a completely normal residential staircase cost? Maybe we would just extend the residential staircase into the attic if it doesn’t cost too much?
the costs are certainly manageable compared to the benefit of the attic, but...
and without garage
Oops... I read so many posts from you about details of a garage and storage room...
a wood-metal design carport
something expensive added again
(looks, in my opinion, 100 times better than such a garage block made of concrete and steel)
Wow... see above
Necessary garden tools will be stored in the utility room,
Oh dear, a lawnmower and the rake in the utility room next to the laundry...
Heirlooms
there’s eBay for that before they rot away on the DB or are forgotten.
I would store the garden chairs for the winter in the attic,
Have you ever lived somewhere? (in reference to the Ikea ad?)
The builder/principal will certainly ask me whether I want a gable roof or hip roof,
No, not necessarily. As a layperson, you go to someone who knows their stuff and tell them your space program. They then advise you regarding costs, space usage, and possibilities.
You of course choose a builder also within your own price range, but the most important thing is trust in quality.
Honestly: if you give me an order, either in my full-time job or my freelance work, and come to me with 100% predetermined specifications, you definitely won’t get my empirical knowledge, my brain, or my passion-driven ideas, which are of course included in the price. In almost every job, advice is part of the philosophy of the (good) entrepreneur... if it’s not wanted, you just put on blinders. Quick money doesn’t stink, after all.
You yourself are currently getting lost in the simplicity of the layperson. That happens to many amateur builders who want to piece their house together themselves. In the end, they end up with the builder who sets their line. Unfortunately, you waste too much time as a layperson with this and that... Or have you ever received a bullseye answer to your contradictory questions?
By the way, I notice that you embed your answers in your questions yourself. A rhetorically bad basis for meaningful answers.
