ᐅ The cost estimate is incomplete – is there anything else I should keep in mind?

Hello dear forum members,

The house planning is now complete, and I am currently gathering cost estimates. One company is our favorite – I have uploaded the cost estimate here. Maybe someone has tips on whether anything is missing.

Detached single-family house, 148 m2 (1593 sq ft), fully basement. Quoted price 294,000 euros

I'll say it upfront: you won't get professional advice in this forum, as most of the participants are amateurs. If this is your preference, please consult a specialist.

Actually, almost every specification says "or similar." This means there is a lot of flexibility regarding what will be installed and the quality, etc.

Checking such documents is a professional field... some people make a living for themselves and their families from it 😉

Otherwise, I can gladly refer to the well-known layperson’s guideline for power outlets: for example, 20 outlets for the kitchen, living room, and dining area might be somewhat insufficient depending on the layout. We had 30 in the construction specification and planned for 31.

I don’t think anyone here can or wants to take on that task.
You can read a lot about the topic, but it is still difficult to properly evaluate a construction specification.
In such documents, every single word is important.
Attention should be paid to terms like “by the builder” and similar phrases.
The biggest pitfalls are usually the things that are not mentioned at all. However, as a layperson, it is hard to recognize those.

A few key points are the payment plan, the timeline, and the details of what materials and components will be used. It should be clearly specified what exactly will be installed. Statements like “brand-name products” or similar mean very little; they only indicate that something may be installed. After all, “brand-name” can mean anything with a recognizable name. ;-)
