ᐅ Contracting out individual trades yourself – what savings can this bring?

When planning our next house, we’re wondering (as a family) whether and how much you could save by contracting the trades yourself and supervising the construction on your own. You definitely need an architect for the documentation and so on, but after managing three houses, you could probably do without a site manager. Right? But how much can you actually save this way, we’re asking ourselves. Fees or percentages weren’t clearly visible on the invoice.

No, the term "matter of taste" is incorrect; it’s more a "matter of perspective"—specifically, perspective distortion: a square has equal side lengths in both dimensions, but if one side is the eaves side and the other the gable side, they appear different. A square floor plan combined with a gable roof visually appears like a rectangular footprint. Interestingly, depending on the viewpoint and roof pitch, people estimate differently which dimension seems "longer"—but they tend to recognize that they are "unequal."

It only becomes a "matter of taste" when the perception is influenced by associations—where the gable roof is seen as old-fashioned, and the hip roof (a roof without a ridge, usually equally sloped on all sides) as stylish.

Honestly, I think that’s nonsense, no offense intended. I assume j.bautsch has seen the square with a gable roof and knows what they’re talking about. You can twist the rules of optics however you want, it was liked and that’s that.

The floor area in square meters (square feet) does not matter for a gable roof, as the square shape is not the focus. Visually, it makes no difference whether the house measures 9x11 meters (30x36 feet) or 10x10 meters (33x33 feet)... as long as the interior layout works, that’s fine. If the appearance also works (beyond certain dimensions the house can look unusual), that’s fine too. Usually, the house then looks like wooden blocks—somewhat bulky. However, this can also be intentionally interesting.

Best regards,

Thanks @kaho674 Whether it is really a 10x10 (square) building and looks like a 9x11 (rectangle) because of the roof doesn't matter to me, as long as I do NOT WANT it to look like a square. And that's not important to me, for example.

Whether the exterior shape is a cube, rectangular prism, L-shape, or anything else doesn’t really matter to me, as long as I like the interior layout.
The fact is that the best ratio of surface area (which accounts for a large part of the costs) to volume (living space, to some extent) is achieved with a sphere. The shape closest to that would be a cube.
The more varied the side lengths are, or if an L-shape is desired, the higher the (shell construction) costs per square meter of living space.
Since most people need to keep an eye on their budget, the shape with the best price-performance ratio is often chosen, which is basically a floor plan close to a square.

Just as a side note: Due to the development plan, we had to change from a hip roof to a half-hip roof. Additional cost on top: 7000 € (about $7,800). We were completely shocked. Then we went to a carpenter friend to have the extra costs explained. Different beams (more wood), more complex beam connections. And as we know, wood is extremely expensive. Now take your simple gable roof and calculate the surcharge to a hip roof. For us, the difference compared to a gable roof would have been around 18,000 € (about $20,000).
