ᐅ Two-story detached house with a gable roof or flat roof

Hello,

There is a development plan for a plot of land to be built on, which does not specify a maximum building height but requires that a new house be adapted to the surrounding buildings. These are typical single-family houses with pitched roofs, built around forty years ago.

Now, a so-called townhouse (or urban villa) with the so-called two-thirds compensatory area is preferred. A construction company has already indicated that this would not be a problem. However, if you sign something here and it later turns out that the building authority does not allow such a house to be built, you are tied to that company—even though you might prefer to build a different, approved house with another company.

Therefore, here are my questions:

1) Is the roof of a so-called townhouse officially also classified as a "pitched roof," or is this term reserved only for the aforementioned single-family houses?

2) If a townhouse is approved, could the single-story two-thirds compensatory area be covered with a pitched roof (to allow a possible later conversion, currently just to be used as an attic storage)? Or would it have to be a flat roof?

Thank you very much for all professional answers and personal experiences!

It mainly needs to fit well, be coherent, and also harmonize with the surroundings. Here is an example of a house with two full stories and a gable roof that, in my opinion (!), looks good. It probably requires an architect.


I like the house, or rather both houses.
Still, the front house is probably not what homeowners who want to build an urban villa (as offered by building companies) have in mind.

The classic urban villa is my avatar image, complete with a hip roof (22° in our region). At least, that’s what many construction companies include under this term in their brochures.
This doesn’t mean every urban villa has to look like this; it’s just the most common version.

A gable roof has the advantage that the roof surface facing south can be larger (if the house is correctly oriented) (see 2 contributors above). A hip roof is less suitable for this because distributing the surface over three sides doesn’t make sense. (If my surface area is three times as large but spread over three roofs, the output will naturally be higher than with only one roof with one surface.)
Furthermore, the hip roof has a flatter shape (smaller angle), which benefits the solar system in warmer seasons (but is less effective in winter).

I also think pNo’s design is worth considering. With a proper knee wall in the attic, this space could actually be used as living area. In our case, the roof is only usable for storage (the highest point is about 1.5 meters (5 feet)).

Our roof was not converted but designed as a cold roof. However, after we laid out the panels on top during winter, we basically had a dance hall.

You can, but don’t have to. Definitely, your roof type offers more possibilities for the attic. Our attic is really not worth considering.

Our house – see the picture – was originally planned as a townhouse with a pitched roof since we knew from the start that photovoltaic panels would be installed sooner or later. However, we were determined to have two full floors.

With some adjustments to the initial designs (for example, extending one side) and fitting the building into a slope, it became more of a traditional house – but still with two full floors. By the way, the rear of the house looks like a single-story building due to its integration into the slope.

What roof pitch do you have on your house?

Best regards,
Sabine

I had to look it up myself first: 32 degrees
