ᐅ What factors make a new house construction expensive?

Good evening everyone,

My husband and I are currently considering whether to start building a new house in 2015 or 2016, and I have been reading a lot here to get a better understanding of the process.

The problem is that most people here already have a rough or clear idea of what their desired house will look like... we still don’t really have that yet.

What I’m actually more interested in is: what exactly are the major cost factors in building a house?

Bay window? Special roof design? Or to put it another way: where can I save money?

Our plot of land is already owned through inheritance, 550 m² (5920 ft²), with a building area of 10 m x 13 m (33 ft x 43 ft). It is already serviced, with utility connections on the property. Fence, shrubs, plants, trees, and hedges are also present since it is an old garden plot. The driveway is already paved.

But what should we build on it? That’s the big question here. Basically, we would like to live on one level on the ground floor, and have the children’s small space upstairs—two kids’ rooms, a heating room, and a small bathroom.

I can hardly go to an architect and ask for 10 different drafts... So it would make more sense if I already had a rough idea beforehand.

So, which trades or work areas cause new construction to become expensive?

Best regards,
Anja

At least one garage or carport, or similar structure, is usually allowed to be built directly on the property boundary. A site plan showing the property and neighboring plots would be helpful.

Oh, that’s possible too? Then I’ll have to dig out the building plans again; they are with the documents I received when I inherited the plot three years ago.

The building zone starts directly at the property line with the left neighbor and measures 13 x 13 m (43 x 43 ft). There are still 8 m (26 ft) to the right boundary.

But building right on the boundary wouldn’t be ideal, as it would place us even closer to the neighbor.

Thanks for the tip.

P.S.: A carport is planned, either a double carport or one on the left and one on the right side.

I’ll look for the documents and upload them here.

What costs money and can be saved:
Basement, dormer, bay window, conservatory, roof window, energy efficiency 40/55%, brick garage, high-quality landscaping by a gardener, heating system with ground-source heat pump instead of gas, very large window areas, finished attic, more than 100 to 130 m (330 to 427 ft) with 1 or 2 children

My Experience:

Expensive Options
- Basement (for large plots, large garages, garden sheds, etc. are often more cost-effective)
- Bay windows, dormers, projections, recesses, complex roof shapes (also less energy efficient)
- Roof windows are more expensive than regular windows, especially if roller shutters are desired
- Balcony (rarely used anyway if there is a terrace)
- Glass sliding door to the terrace

Affordable Options
- Raising the knee wall to gain more space (for example, what do you think about


Single-family brick house with solar panels on the roof, terrace, and garden.


- Floor-to-ceiling window instead of a normal window
- Box-shaped house with a gable roof or a mono-pitched roof

However, the most expensive option is choosing a construction company that is too cheap and then goes bankrupt.

Hello jx7,

in response to the OP’s question about posting a house (example) that becomes more expensive mainly due to the offset—which, by the way, runs around the corner—especially because of the wooden inserts, it’s quite understandable.
