ᐅ Unequal Width in Planned Semi-Detached House

Hello everyone,

I’m new to this forum and have a question about our building project. We have the opportunity to purchase a discounted building plot (approx. 350m2 (3750 sq ft)) for a semi-detached house in the outskirts of Munich. The contract for this is already available to us.
The plot for the other half of the house was sold four months ago. Last week, I was able to get in touch with our future building partners, who already have approval for the following semi-detached house:
- Model Danwood 116w
- Gable roof
- No basement
- 2 full floors, no option for attic space
- Dimensions 10.2 x 7 m (33.5 x 23 ft)
- Wall height 6.2 m (20.3 ft)
- Roof pitch 25°
- Total living area 116 m2 (1248 sq ft)

And here lies the catch: we are a family with soon two children and a need for a large home office. Therefore, 116m2 (1248 sq ft) is definitely too little space for us. After consulting with the local building authority, it would be possible to keep the length of 10.2m (33.5 ft) that borders the neighbor but build our half wider (up to 9 m (29.5 ft)). Also, building without a basement is not an option for us. Then we would have:
- Basement
- Ground floor plus attic with external dimensions 10.2 x 9 m (33.5 x 29.5 ft)

So, I think we could realize about 135–140 m2 (1453–1507 sq ft) of living space.
Now my question to the forum: would you build such an asymmetrical semi-detached house?
Of course, it’s frustrating to have to adapt to the shallow roof pitch and limited length. At the same time, it might also be nice to have two relatively spacious floors. There would of course be the option to decline the plot altogether – but given its location and price, that is not our preferred choice.
Maybe someone has experience or tips for a rather unconventional semi-detached house! We appreciate any feedback.

Although the original poster clearly states that the basement is non-negotiable because they want the space. [ < ] If you raise the basement by one meter out of the ground, you can install great windows and have fully functional rooms. Without expensive and vulnerable roof windows and without awkward roof slopes. Space for a utility room, technical equipment, office, workshop for people who want to work all year round, hobby room, and even a children's bedroom.

We have already understood that the original poster is willing to risk everything (no matter the cost, even if it means the house) on the "Pyrrhic victory of the head-first-through-the-wall basement" plan. A basement under a raised ground floor is objectively ruled out here, because the height restriction applies equally – this height would have to be compensated elsewhere (I doubt even the minimum allowed room heights would be sufficient). We still do not know the zoning plan, but the newer these are, the more often they limit the finished floor level of the ground floor to a maximum of half a meter above street level. Deep down, I could have agreed with your suggestion, but who would it help?

So you are looking for reasons or a purpose to justify having the basement as an "absolute must-have"?
Especially with a semi-detached house, there aren't many options. Utility basement. Storage space. Expensive warehouse.

And when you consider your budget expectations, it becomes even more unreasonable. If I have limited funds (which is relative when building a house, as half a million isn’t necessarily a lot), I try to find practical uses for the money. A basement ranks far down the list of reasonable expenses.

Oops, I completely missed this: that the possible uses for the non-negotiable basement still have to be found, meaning the basement is being built purely out of FOMO (or even fears that without a basement, the basement spirits might be forced to wreak havoc above ground, and who knows if they would be satisfied with harmless mischief)?
I wish I had that much money too. But I'd probably prefer to go on a world trip with an audience with the Pope—and fun fact: I’m Protestant, don’t have a daughter, and I’m not interested in men’s boutiques in Wuppertal.
