Property developers with less experience should be particularly keen to read on: in our guide we provide you with some useful tips for before you start construction: 1. Make your ideas concrete: Think about exactly how large the structure should be in advance. This is because the costs of new construction increase linearly with the volume of the building. Build less, and you'll pay less as well. 2. Proceed cautiously and with determination: You can already save money in the planning phase by giving yourself sufficient time and developing different variants with an architect. Then make a final decision for one version. No hesitation or indecision is the motto. Replanning in the actual construction phase can be expensive. 3. Lay out your project with as much detail as possible: This is important so that your architect can carry out your request for quotation exactly. All elements or trades of the new building are listed, including a description of quantity, performance and quality. You present this request for quotation to various craftsmen so they can make you an offer. You can discuss with your architect which service providers are suitable.
