Collection of tips to reduce construction costs

Hello everyone,

I would like to start a collection of concrete tips for reducing construction costs. What have you been able to achieve to lower construction costs? Which tips/tricks have saved how many euros?

We keep discussing approximate house costs, but it would also be interesting to have concrete cases where money was saved. For example:
Roof window size XX instead of dormer, approx. savings XX euros
Standard patio door instead of sliding lift door, approx. savings XX euros
Wooden stairs instead of concrete stairs, approx. savings XX euros
...

Of course, general self-help or similar reduces costs, but to consider how I can build my house even cheaper, that doesn’t always help anyone.

I would be very happy about your input – and many others surely would too!

Nonsense... there are no secret tips and tricks, only the market... in that sense: Good planning... that saves you square meters and thus a lot of money Simple geometry Renunciation and discipline Don’t save in the wrong place

Camping wild in the forest saves costs for land, house, and ancillary building expenses. Savings of at least six figures!

Lego bricks instead of normal bricks!
