Yes. Extensions, demolition, structural work, installations and finishing can form part of one renovation. We discuss which tasks belong in the scope and how they fit together.
Once the necessary preparation is complete, the agreed scope can be priced. The quote sets out the work, provisional allowances and exclusions. Changes and unforeseen work are discussed separately.
This depends on the work, the address and local rules. Check your plan through the Dutch Omgevingsloket and have structural alterations assessed in advance. Work that does not need a permit must still comply with applicable building rules.
