Hello dear housebuilding forum,

I hope I have posted my request in the correct subforum. We have been searching for around 3 years for a place to live so we can move back to our families in our home region of southern Hesse. Currently, we are living in Bavaria, and since we are comfortable here, the pressure to find a house is low and our requirements for a new home are high. About a year ago, we almost succeeded in purchasing a property, but unfortunately, the seller withdrew at the last minute.

We are city people and would be happy in either an apartment or a house. We are not gardeners, so a large garden is more of a disadvantage for us. A nice terrace for barbecues, reading, and having drinks is more important. To us, a beautiful garden consists of grasses, trees, and wildflowers.

Two weeks ago, we found a property that might be suitable again. Since the situation is somewhat special, I would like to ask for feedback and advice on critical issues here. It concerns a plot with an existing building of about 800 m² (8600 ft²). The existing building is to be demolished, the plot subdivided, and two semi-detached houses built. The offer is through a real estate agent who is also a partner of Luxhaus, but is involved in traditional construction as well. It is not yet clear to me whether we must build with Luxhaus or if the builder associated with the agent will be involved.

This week, I will meet with the real estate agent and the architect from Luxhaus to discuss possible plans and receive a cost estimate. I have the Luxhaus construction specification, which is about 100 pages with many detailed points. I can upload it if needed; I suspect it is also easily found online. I will share a floor plan as soon as it is available. It is still unclear whether we are allowed to build the area and height planned on the plot. According to the agent, the city offers some flexibility based on the HBO regulations effective from late 2025. Nothing is signed, so everything is still non-binding. There is another interested party for the second half of the plot.

Comprehensive support and completion of the house by partners is very important to me because, due to my work and the distance from my current residence, I will have little input during construction.

Below I have included the questionnaire and our room program, which I have already shared with the agent. I am aware that this may involve a linked transaction with possible implications for property transfer tax. From here on, I would appreciate questions, advice, and other input to help me make informed decisions.

Hello,

for that price, I would not accept a semi-detached house, especially not one with drywall partitions from a prefabricated house manufacturer.

I am familiar with the package deals for land and house from Luxhaus, but I advise you to stay away and look for another plot.

Even better: buy the land outright, find a partner for a detached house, and build two single-family homes. You can also bypass the real estate agent if you get in touch with the owner directly.

Best regards

Why not? Quality comes at a price.

Are “solid” walls better? If so, why do you think that?

... and not be able to get the purchase financed by the bank...

If, not when, two detached houses are even possible. After all, you have to legally divide an (unknown) plot, and then fit two houses on it with the required setback distances. If the plot is relatively narrow, you’ll probably lose interest. Trying to fit two single-family homes with all the setback requirements on a 20m (66 ft) wide lot will result in houses that are even narrower (though longer) than a semi-detached house would be.

But that does not release you from paying the brokerage fee. The agent can and will sue for it, and will win 100%.

Coordination with the second buyer is planned if it comes to that,

Hopefully this only means if the purchase actually goes through. You definitely shouldn’t leave it up to chance whether and when the seller finds a buyer for your neighboring half. For example, the subdivision (in my opinion, often better as a notional share) is just as important to secure as the possible mediation between a house without basement and one with basement. The worst case would be if the seller arranges the subdivision, you buy one half, and then he sells the other half to some complete fool and/or unpleasant person. If you can easily cover an additional $40,000 premium out of pocket for including the construction costs in the basis for real estate transfer tax assessment, that suggests a creditworthiness that could enable you to buy the entire property just to keep control over the choice of neighbors. I would probably buy the property not for myself, but for a property development partnership for Child 1 & Child 2. Most taxpayers tend to overlook the tax advantages arising from the difference between commercial capacity and legal capacity — to the benefit of the tax authorities ;-)

Thanks, 11ant. I am familiar with the Goalkeeper thread and your related posts.

Just the sheer length makes “knowing” this thread almost as challenging as “understanding” people of the opposite sex. What is often overlooked about the Goalkeeper thread, by the way, is that it is more than just a cautionary tale about dealing with dumb and neo-dumb middle-house neighbors as well as the rather foolish mayor. It also includes, for example, a functional house design* with a width of seven meters (about 23 feet), whereas the “GDB Bottles” model favored by the “usual suspects” is based on six meters (about 20 feet) width. This seventh meter makes a significant difference for the staircase concept, even though the core layout remains (each at least applied) in the central part of the semi-detached house (i.e., near the ridge in the middle third of the depth). The ninth meter of width opens up the possibility of a landing between two straight flights of stairs. That also means it can be attractive to divide the total house width asymmetrically — for example, into nine and seven meters.

* More precisely, there are several: besides the one implemented, at least one proposal from, I believe, Kerstin.

It may be true that the owner’s family actually has that name – yet I suspect the name "Luxhaus" is meant to create a deliberate association. I’m nearing sixty, but I am still younger than the last (German) “prefab” houses with cardboard walls.

I agree with buying the entire plot. However, not with detached single-family homes: the original poster’s family is only a few years older than the core target group for terraced houses, whose most urban and economical form is the semi-detached house. Detached single-family homes in urban residential areas are becoming outdated, like cars used by only one family on the street in ten years’ time.

If the plot is, for example, relatively narrow, you’ll lose interest. Developing a 20m (65.6 ft) wide lot with setback distances everywhere and two single-family homes leads to even narrower houses (but really long) than would be the case with a semi-detached house.

As you actually know, detached houses do not necessarily imply a legal subdivision; and the setback requirements are not necessarily caused by the type of division.

Thank you for the lively discussion.

Calling myself familiar with the Goalkeeper thread is probably an exaggeration. I read it in full some time ago and plan to revisit it again this week. Coordination with a second party will take place before any possible signing or purchase. I understand the difference between legal capacity and commercial capacity, but is there really any meaningful room for arrangement when it comes to a property intended for personal use?

Even though an additional cost of 40,000 euros (about 43,000 dollars) is manageable, there is a limit beyond which purchasing the plot is no longer an option, neither for us alone nor for sharing; to my layman’s understanding, two detached single-family homes wouldn’t fit on it either. The appointment with the architect is on Thursday evening—no quotation marks—who apparently offers genuine architectural services alongside his collaboration with Luxhaus. The joint deal seems to be more connected to the real estate agent and the involved architect, rather than exclusively tied to Luxhaus.

Which plot of land is it? Aren't they all already developed?
