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

We 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).

City villas ... are probably not that demanding in terms of construction either (although I’m taking a risk with that claim ) Self-awareness is the first step toward improvement..!

Why don’t you go to the architect? You are exactly the kind of client this professional group serves...

The local prices, which were confirmed to me again at the last building fair (and within the range of a concrete offer I have), are roughly between 1,200 and 1,300 EUR for the standard package (meaning underfloor heating, no controlled mechanical ventilation, gas heating, including groundwork for soil classes 3-5, natural stone window sills, basic but adequate electrical installation with network/SAT wiring, crank-operated shutters, finished except for flooring in living and sleeping areas as well as wall paint). The provider from whom I have an offer of almost exactly 1,250 EUR per sqm (square meter) seems to be reliable according to several online construction diaries and the price appears realistic (i.e., no hidden costs, additional charges, etc.).
Extras, of course, cost extra, but I would not calculate them per square meter. A nicer staircase is simply a nicer staircase, regardless of the house size. An air source heat pump instead of gas heating, better sanitary fixtures, higher-quality interior doors, and so on.
For 150 sqm (1,615 square feet), I come to about 188,000 EUR plus extras (controlled mechanical ventilation 10K, air source heat pump at least a few thousand EUR, etc.).
Since most new apartments for families here have 4 rooms and 90-100 sqm (970-1,075 square feet), I do wonder if 150 sqm (1,615 square feet) might be a bit excessive.
And of course, I am serious: I neither want to live as three people in a two-room apartment for a long time, nor do I want my binding land reservation to expire. The real challenge might be that I don’t have a fixed budget and I’m not necessarily set on roof style y. In the end, I want a solution that balances price and performance in a reasonable way. Diminishing returns, etc. (One child’s bedroom is a must, two child bedrooms are basically essential, three child bedrooms would be a nice bonus, seven child bedrooms are too many – how much is the first and second child’s bedroom WORTH? How much is the seventh child’s bedroom WORTH? Small hint: construction costs are always the same, but the VALUE for us and for most other families is very different between the 1st child’s bedroom and the 7th.).

Sebastian7925 Jun 2015 00:51No, it should have been "the clientele."
I still don’t know his budget, but his house prices are more than ambitious.
We also know that the plot of land hasn’t been purchased yet – I suspect that nothing will have happened there in 10 years.

No, it should have been "the clientele" I’m a few days older; thank Mother Nature, some things remain unchanged — regardless of any spelling reforms.
*Clientele, noun:
The entire body of clients or customers
*Client, noun (singular): someone who seeks advice or help from another person for payment, who is hired to represent their interests
*Source: Duden
Singular is the key word... or did I miss something along the way...?
