Yes, the 4000 euro estimation includes all possible costs (notary, VAT etc) and therefore also the finishings. This means that if you are good at DIY or if you are happy with cheap solutions, you can probably deduct 200-300 euro (per square meter) from this price.

We ended up using 4000 euro per square meter based on the assumption that we’ll go for a site that makes it possible to only pay 6% VAT and also on the assumption that we need to add some money to the architects 3500 euro estimate to take into account the future-proofing investments that are in the Blueprint 1.0.
