House Design
Who Designed it: Architect from a construction company
What Do You Like Most? Why? Side driveway to garage, direct access from garage to house, separate apartment concept, open ground floor design, upper floor is perfect in our opinion, gallery
What Do You Like Least? Why? Living/dining area is somewhat too large (wife worries it may be hard to arrange cozily), bedroom window position in the separate apartment is tricky, (north entrance → long access route for guests)
Preferred Heating System: Air-to-water heat pump + photovoltaic system + battery storage

If You Have to Cut Back, On Which Details / Extensions
- Can be cut: Office on upper floor, a few square meters in living/dining area
- Cannot be cut: Remaining room program

Why Has the Design Turned Out As It Is Now?
The room program was provided by us. Furthermore, many requirements and the plot itself influenced the design.
Why Was the Drawing Created in Sweet Home 3D?
The architect’s design is drawn to scale but not dimensioned, so I transferred it to SH3D.
What Is the Most Important / Fundamental Question About the Floor Plan, Summarized in 130 Characters?

Definitely an improvement, I would say. The walk-in closet and bedroom still need to be swapped, although I would also reduce the size of the walk-in closet and allocate more square meters to the bedroom. Then, of course, the corridor could be reduced as well, resulting in a very large bathroom. (Sketch(!)) This raises the question of whether the square meters could be rearranged differently so that there would be a master bathroom and a kids’ bathroom. However, with a house width of 7.75m (25.4 feet), this is not an easy task.

The corridor on the ground floor is a bit too narrow, in my opinion. Once the kitchen cabinets are planned, you can see how many centimeters remain for the corridor.

If the ground floor home office is used as a guest room or second bedroom, I would swap the utility/storage room with the shower on the ground floor so that you don’t have to pass through the entrance area to reach the small bathroom.

Do we have an overhang on the right side according to the plan? Is that intentional? Some views would be helpful.

What is the purpose of a vestibule? Essentially, it is just one extra door. A hallway feels more welcoming if it is also illuminated from the entrance side by windows, among other things. Be sure to plan ample closet space for coats and outerwear!

Additionally, when arranging the children's rooms, consider dividing them so that the smaller room receives a corner for a built-in wardrobe taken from the other room. This not only balances the size difference but also turns the planning error of the door positions into a positive feature.

Then, of course, the hallway could be made smaller, resulting in a huge bathroom. (Sketch(!))

However, given the 7.75m (25.4 feet) house width, that’s not an easy task.



The hallway on the ground floor is a bit too narrow, in my opinion. Plan the kitchen cabinets – then you can see how many centimeters remain for the hallway.

Bedroom and walk-in closet will be swapped. The bathroom would then be approximately 20m² (215 sq ft) – somehow very, very large.

If the home office on the ground floor is used as a guest room or second bedroom, I would swap the utility/storage room with the shower on the ground floor so that you don’t have to go through the entrance vestibule to reach the small bathroom.

The measurements refer to clear distances between walls. Exterior wall thickness is 36.5cm (14 inches), interior walls 25cm (10 inches). We basically do not need a children’s bathroom. The hallway on the ground floor is 1.30m (4.3 feet) wide, in the entrance vestibule 2.50m (8.2 feet).

Yes, there is an overhang on the right side of the plan, covering the entrance on the ground floor.

Also, the children’s rooms should be arranged more thoughtfully, and the smaller room should have a corner carved out for a built-in wardrobe from the other room – this not only balances the room sizes but also turns the flawed door positioning into a positive feature.

The wall in the entrance vestibule would be entirely glass, so not masonry. Whether it will be built at all is still uncertain. Thanks for the tip regarding the children’s rooms, that makes absolute sense.

Small update:
Tomorrow we will receive the offer for the latest floor plan from our currently preferred general contractor. Additionally, a second general contractor will also prepare an offer based on the floor plan.
Alternatively, we have a meeting on Wednesday with an architect through whom we would realize the house using a contract package system. The more I research and study the topic, the more I lean toward using a contract package approach. Let’s see how the discussions go.
