ᐅ House without a garage and basement? Converting the attic? Vent pipe?

GrymWe have been considering the following:
If we want to build without a basement and without a garage, preferably with just a carport, does it make sense – and what would the cost difference be – to convert the attic instead?
We plan to build a structure approximately 10.50 meters x 8.50 meters (34.4 ft x 27.9 ft) along the street. On top, a gable roof with a 45-degree pitch (alternatively: only 40 degrees), and the knee wall on the first floor should be about 1.40 meters (4.6 ft) high. At the highest point, the interior height would probably be around 2.80 meters (9.2 ft).
Instead of insulating the top floor ceiling, we would insulate the roof. For cost reasons, the top floor ceiling would remain a wooden beam construction (I assume?). The attic would be an unheated secondary space but equipped with at least one ventilation opening.
The staircase up to the attic should be reasonably comfortable. What is the cost of a standard residential staircase? We might simply extend the living area staircase to the attic if the additional cost is not too high.
In the medium term, we want a wood-and-metal design carport for two cars next to the house, with bike racks in the rear area (which in my opinion looks much better than a concrete and steel garage box). The bikes would be weather-protected but quickly accessible. Necessary garden tools will be stored in the utility room; unnecessary items, seasonal goods, heirlooms, etc., will go into the attic (within the thermal envelope and ventilated by a controlled residential ventilation system). Likewise, winter storage of the garden chairs would be in the attic; in summer, they will remain outside permanently.
It is also unclear whether and what kind of equipment could be located in the utility room (ground or air source heat pump, controlled residential ventilation system, hot water hygiene storage tank, etc.).
Another question is what the cost impact would be for this kind of attic conversion (planned from the start and carried out by the general contractor) compared to the standard option (insulating the top floor ceiling, insulated pull-down stairs to the unheated attic space).

Sebastian7924 Jun 2015 21:13But why don’t you consult someone who can actually do the planning?
You’re approaching this completely the wrong way – going back and forth, changing this and then fundamentally changing that. In the end, you’re not making any progress and you’re not taking any advice…
Again: Why don’t you go to a planner and share those designs? In the green forum – no matter what people might think of some members there – you’re not getting such harsh feedback without reason.
You might be good with numbers, but planning a house doesn’t seem to be your strength. It’s a shame to waste time like this – how much longer do you want to keep dealing with it?

First, find a model that roughly makes sense, and then I can bother the general contractor (GC). The GC will probably ask me whether I want a gable roof or a hip roof, two full stories or not, whether the attic should be finished or left as it is, and so on – I could just tell them to calculate all 322 variants and give me the prices, since I have no idea what makes sense. It always depends on the price/performance ratio. For such preliminary, vague discussions, that’s what online forums are for.
And once I have a rough idea of the direction I want to go, then I can ask for cost estimates for 3–4 variants instead of 322. In the end, I would never blindly trust a GC, since they will also be thinking about their own profit.

From what I have read from you so far—and I think I could see this clearly in a personal conversation—I would advise caution. Without a planning contract, you wouldn’t even come close to being able to "bother" me. Grym schrieb:
