Because our plot is relatively long and narrow (20x43m (66x141 ft)), we have already given some thought to the possible arrangement of the house and garage. Here is the thread on that topic.

At first, we focused on the first variant with the garage located above the house to the north. However, with the garage and house together, it would have become very tight toward the south. The architect's first draft surprised us (garage on the east) but we generally liked it very much, so we are now presenting this as the basis here. Many of our wishes have already been met, and the draft is definitely a good starting point. I have to add that currently we do not have any eastern sun exposure and do not consider this a problem. The only drawback is that the house stands relatively centrally and garden space is “wasted,” partly due to the 6m (20 ft) setback on the east. But we will submit a preliminary building inquiry to possibly reduce the distance to 3m (10 ft).

So, here are the plans. North is at the top of the plan.

Our bathroom measures 3.3 m by 2.45 m (10.8 ft by 8 ft) and feels quite spacious. Even when we help the kids brush their teeth, it doesn’t feel cramped... so I don’t think it’s too small.

I’m quite glad about the extra row of bricks and the resulting clear ceiling height of 2.6 m (8.5 ft) on the ground floor. Apart from possibly slightly higher costs, there are no downsides.

Is it a modern invention that everyone has to fuss around in the bathroom at the same time? After all, there is also a full guest bathroom.
In our house, the bathroom was locked before, and we were five family members sharing only one bathroom.

I don’t think you have to invent uses and personal needs.
Some people lock the door, others don’t. But why would you lock the door if you only want to use the sink to brush your teeth?
Even if it is agreed within the family that, for example, the downstairs toilet is used in the morning (it’s not uncommon for children to be with a parent in the bathroom, at least in the first years), they get in each other’s way in front of the sink (a double basin). I experienced this myself and then installed a sliding door in the bathroom—even though there were only two of us. My parents had and still have the same situation, with the result that the first sink remains dry—as a place for brushes and makeup stuff.

In this regard, I find my comment completely justified.

Overall, I don’t find the bathroom small, but I do find the washing area too cramped with the door right behind you at neck/shoulder/hip level 😉

1. But then the kitchen tends to become even bigger and the living room smaller.

Not necessarily. You still have to place the pantry… you could also put it on the inner wall (without looking at the plan again now).

Also, I would prefer the living room on the south side.

Why?

Sure, everyone has different priorities. But if you want both a towel radiator and a tall cabinet, it becomes quite challenging.

I don’t know the exact dimensions of the bathroom, but I think it is roughly the same size as ours.
In Winterkind’s thread, Yvonne sketched a bathroom layout that pretty much matches ours.

Our bathroom includes a walk-in shower, a standard bathtub, a washbasin with a cabinet hanging next to it, a toilet, and a heated towel rail. Everything fits and it is quite practical to use, even with a child.
However, it doesn’t have enough seating for four people to use the toilet simultaneously. 😉
Jokes aside, it is functional, but of course not as spacious or luxurious as the glossy brochures showing 2 m² (21.5 sq ft) of shelves around the bathtub rim and a sea view from the tub.

According to the design, the bathroom is approximately 2.70 m x 3.70 m (9 ft x 12 ft). Would it be possible for you to send us the floor plan of your bathroom? That might help us with further planning.

Why?
Because we prefer more sunlight in the living room than in the kitchen and pantry. Also, the living room would then be located in the northwest, which is definitely not ideal for us.

Thank you very much for the pictures! That’s definitely a good idea. What are the dimensions of your bathroom?

Guest bathroom measuring 2.4 m x 2 m (7.9 ft x 6.6 ft):

Main bathroom measuring 3.28 m x 2.4 m (10.8 ft x 7.9 ft):

Floor plan of a bathroom with bathtub, toilet, and sink


Both shower enclosures are made of glass – in the main bathroom, the shower ended up being 1.2 m (3.9 ft) wide instead of 1.4 m (4.6 ft), and the bathtub has about a 10 cm (4 inch) platform on both sides. The door swings the opposite way. Behind the door are wall shelves; at the end of the "hallway" (top of the plan) there is a wooden towel rack.
