Hi,

after our first design turned out to be unrealistic budget-wise based on the initial offers, we discarded the plan with a basement and integrated garage.

The new plan is to build a lower ground floor on our south-facing slope, including a bedroom, two children’s rooms, a family bathroom, and a utility/technical room. Then on the ground floor, there would be an open living and dining area, a small pantry, a wardrobe area, and a shower bathroom. From the ground floor, you would then access the northwest garden and the terrace. The main entrance should be on the ground floor. We would prepare the attic for a future conversion or possibly integrate an office there if the budget allows. For now, the office will be set up in the second children’s room in the basement until it is needed! A carport or garage should be located on the south side or, if possible, on the east side.

Has anyone here completed a similar project or is currently planning one? Photos or ideas of floor plans would be great!

We would appreciate any feedback in any form. I have attached the list of details about the plot as well as a site plan! Our plot is number 6!

How was the positioning of the house decided? Would it be possible to move it further back?

I don’t want to check right now... But one thing is clear: there is a pinch at the bottom, and there is more space upstairs than needed. In that case, rooms should be rearranged instead of leaving upstairs unused and enlarging the lower floor. I would suggest placing the parents’ bedroom upstairs, and the children’s rooms and the home office downstairs.

I don’t find having parents’ beds above and children’s beds below ideal for such young kids. However, children don’t need their own room for a long time, and until then, a children’s room can serve as the parents’ bedroom.

I would divide it differently and try using a rectangular layout.

Hey, yes it could be moved, the position isn’t final yet... this was just a first new draft.

Thanks for rotating the plans and for the feedback... we will take your suggestions on board and improve the draft.

It gets really tight downstairs if every room is supposed to have a window, and I wouldn’t want a bedroom, bathroom, or walk-in closet without one.

So this design doesn’t work.

Since the budget seems limited, you can’t just keep expanding. Making the basement large enough to fit all the rooms with windows is therefore out of the question.

I need to consider a different layout.

I would put the living, dining, and kitchen areas downstairs. That way, there can be enough windows, and the terrace is directly accessible from the dining area. The pantry and freezer room don’t need windows. I would definitely plan for a guest toilet there, and while it’s not ideal without a window, it can work with good ventilation. Maybe you could squeeze it into the back right corner of the plan and add a small window.

On the ground floor, I would plan children’s bedrooms and an office with a bathroom. There is not a second child yet, so one of the rooms will initially be a bedroom.

Upstairs, you can eventually create a nice master suite with a walk-in closet and spa bathroom.

The kids (and the parents!) will survive if the children’s bedrooms are not on the same floor as the parents’. For toddlers, a baby monitor helps, and otherwise, there is just a staircase—not a jungle—to overcome when checking on the kids. My brother has three children, with only one sleeping on the same floor as the parents. I have not noticed any significant problems for either the children or the parents because of it (and the last child got a room upstairs by taking part of what was originally a very large bedroom).

This layout also has the advantage that teenagers don’t have to walk through the main living area with their friends. I would consider possibly preparing hookups for a kitchen in the ground floor office. That way, when the parents stop working (and maybe a small desk in the master area suffices), the teens could have their own space if they’re old enough to take care of themselves.
