Before I give this architect a kick, it would be more appropriate to compare your modifications against his planning. Usually the layman makes everything worse with his "improvements."
I would have to compile that.
What does adjust mean? Moving a wall by 30cm is not enough here.
You must!
Okay, that was clear.
So including ancillary construction costs?!
… that won’t work even with a lot of own work involved.
Cross out garage and basement and possibly another 20sqm of living space, then it might work.
So
160sqm x €3000 …. €480,000
Ancillary construction costs €50,000
Minus own work €30,000
Then you would manage with €500,000!
Good, then back to start! Here are once the basic thoughts from us (on the procedure and the design I presented - I hope that helps):
Development of the property ultimately only possible from southwest or southeast (i.e., at one of the two building boundaries)? Two parking spaces must be present on the property, whereby it must be taken into account that parking spaces in front of garages and parking spaces arranged one behind the other without their own free access are not recognized as parking spaces (this is so in the determination). That means a single garage with a narrow driveway without an additional parking space is ruled out. There are no specifications regarding ridge direction. Single-sided shed roofs must be built with the lower part of the roof towards the street. All roof types allowed. Restrictions (offsets) for recessed top floors. The terrain has a slight slope along the southwestern property boundary, as can be seen in the front view.
We initially excluded development from the southeast (building boundary bottom right). Background: after deducting the setback areas, not much buildable area remains (very narrow), without generating special forms, e.g., along the building boundary (more expensive!). The garden resulting above would possibly have some morning sun very early, would be shaded during the day by the building, but would have some evening sun, though only in summer. Depending on the design of the parking spaces, e.g., by a garage, there could be additional shading here.
For the above reasons, we decided on development from the southwest. After that we proceeded further with the determination and space requirements. Roughly summarized, we arrived at the following space requirements:
[*Upper floor
[LIST]
[*]Office
[*]Child 1, 2
[*]Master bedroom
[*]Bathroom with walk-in shower
[*]Small storage room
[*]Ground floor
[*]Living and dining area
[*]Kitchen with small storage room
[*]WC with shower, ground level
[*]Guest room, ideally convertible to an office
[*]Basement
[*]Large workshop
[*]Storage room
[*]Laundry room
[*]Technical room
[*]Optional sauna
Cross-cutting requirements that we believe had direct influence on the design:
[*]Planned is a controlled residential ventilation system with Spiro pipes, therefore preferably a technical shaft as central as possible in the house where risers for ventilation etc. can be routed.
[*]Laundry chute
[*]Fireplace wish
[*]Wide staircase, desired width approx. 1.1m
[*]Roof designed accordingly for a large solar system
[*]Garage
[*]Balcony
Based on that, we eventually arrived at the currently available design.
Now, as I see the whole thing, the red pen must be applied. So a rectangular house shape would be most suitable, without frills. On the upper floor we would cut out the office, on the ground floor reduce the living and dining area, in the basement the optional sauna. The balcony will probably be omitted then as well. I would be reluctant to give up the garage, possibly the basement below it though and increase the budget for that a little... Then you could probably get a good deal further, right?
Why is the boundary garage 10 m long on the boundary?
12 m are allowed.
Why 6 m distance of the garage to the street?
5 m minimum must be maintained, although 6 m fits better for vehicles. Under 6 m becomes quite tight.
In which direction is the prescribed ridge direction?
No specification, except for single-sided shed roofs, see above.
It can go like this without a basement. Possibly with garage?
or like this
The second proposal has something. What does CP and Abs mean in this case?
Because you have to have that in front of a garage, unless the development plan allows less.
The nice thing about a shed roof and an allowed 10 meter ridge height is that you could cover the roof fully with photovoltaics and still be able to put windows corresponding to the window.
That’s why we ultimately decided on a shed roof because of the solar criterion. What do you mean by putting a window next to a corresponding window?
But here is a house with approx. 9.80 m height, allowed eaves heights on roughly named property.
Orientation of the roof surfaces roughly north-south. And under the shed roof two nice living rooms as well as enough storage space are generated.
In this case the driveway is not successful, as it is too long (carport with AB behind the house), but everything could be planned better.
What is an AB? That would be similar to the proposal from hanghaus2023, right? I like the approach, but does it also fit the parking criteria as mentioned before (hard to estimate by the dimensions)? What do you do with the long driveway? If you move the garage forward, a small north garden will form in the back – how could that be used?
