Hello everyone,
After reading a lot here and planning for three months now, I’m trying to get some help.
The plot is complicated, maybe a bit narrow to also fit a separate apartment on the ground floor.
We are unsure how to “split” the plot.
Who should get the west or east side?
Which street should the house face?
The 5.5 m (18 ft) setback area on the north side suggests itself as the driveway/parking area. Also, no one wants a north-facing garden.
We all want sunlight somehow, but with further construction progress on other houses (marked in red) and the low sun angle, hardly any sun reaches the southern area.
The separate apartment really only needs a sunny terrace (because mowing the lawn will get harder with age).
I’ve simply added the architect’s two drafts here.

We often complain that granny flats are designed as tiny spaces. In this case, it’s the opposite—63 to 67 sq m (680 to 720 sq ft) is quite large. Isn't that actually a good thing?

Does the mother definitely have to live in a granny flat? Wouldn’t a well-designed single-family home plus a suitable apartment in the town (rented or bought) be another option? Thanks for the suggestion.
The alternative: She buys a 100 sq m (1,076 sq ft) penthouse apartment with rooftop terrace and elevator—10 km (6 miles) away.
Then we’ll just build a simple single-family house with a bedroom on the ground floor and a double garage.

Thanks for your insights.
That actually ends up more expensive in proportion. First, it’s 100sqm (1,076 sq ft), and secondly, adding “pent-” before attic apartment turns it into a goldmine for sellers or landlords.
However, I don’t see why someone under 70 should still buy; renting works just as well.
But I assume you’re getting the initial capital, i.e., her equity, so why not plan for the granny flat as well?!
Yep, you’re right. It always depends on the circumstances.
I’ve attached a room layout sketch for reference. The upper floor is basically a test to see how much furnishable and functional space can fit.
That should total around 240 sqm (2,583 sq ft).
Regarding the budget: affordable builders usually offer their houses at about 2,500 €/sqm (around $232/sq ft). However, this is based on their specific list of construction services. Then you have additional upgrades: at least a larger water storage tank here, an extra electrical cabinet, more sockets than the standard allows, and so on. It basically only ends with floor tiles and coverings, which you usually have to provide yourself in a self-build. These are based on experience. Those who paid less often spend a year or two or more working on their house themselves and have contacts with various tradespeople.

North is up on the plan, the utility room is about 10 sqm (108 sq ft).

Altogether, I come to nearly 260 sqm (2,798 sq ft) across 2 residential units.

That is relatively more expensive. On one hand, 100 sqm (1,076 sq ft), and on the other, a “pent” prefix turns an attic apartment into a goldmine for sellers or landlords. That was a bit exaggerated now

However, I don’t see why anyone should buy with an interest rate under 0.7%, renting is also an option. But I assume you are receiving the initial capital, the equity, from her, so why not plan the granny flat? Exactly, but why rent if you have the necessary equity?

I have attached a room layout sketch for you to see. Thanks. A kitchen without a window takes some getting used to – but it’s doable. I like the entrance area, but unfortunately it probably won’t be possible to have the entrance and garden on the same side.
Regarding the budget: We are fully aware that small extras here and there add to the cost. But fortunately, we have plenty of contacts with tradespeople and the experience of having built a house before.

Exactly, but why should you rent if you have the necessary equity? Because the intention for living in retirement is quite different. In that phase, you don’t want to tie up your existing retirement savings long-term in a property or elsewhere, but rather be able to react spontaneously when needed.

The garden is facing south. Strangely, the plot is arranged so that you can see the south from the west side.
Regarding the kitchen: this is just an example of how it could be done.
