In the last couple of years, actors in the construction industry have shown an increasing willingness to move towards circular businesses. However, many consider circular construction to be a more expensive option, which makes actors reluctant to invest in circularity. This study contributes to the existing literature by relating the Level of Circularity (LoC) for a one-family house to its Life Cycle Costs (LCC). Using design-orientated research, the design of the one-family house was altered to gradually increase its LoC. The results revealed that it is possible to double the LoC to 0.41 compared to the initial design (LoC = 0.20) without increasing the LCC. Furthermore, the measures do not require radical changes to the design and construction process. Rather, it only requires replacing virgin materials with recycled or biological materials, and using building products that can be disassembled relatively easily. The results also revealed that increasing the circularity level further resulted in a sharp increase in product costs, and therefore an increase in LCC. This makes it less economically attractive for construction companies. Therefore, we suggest starting with relatively easy measures, which can already double the current circularity level of typical one-family houses.

在过去的两年中，建筑行业的参与者显示出越来越多的意愿转向循环业务。但是，许多人认为循环构建是一种更昂贵的选择，这使得参与者不愿投资于循环。这项研究通过将一户房屋的循环水平（LoC）与生命周期成本（LCC）相关联，为现有文献做出了贡献。通过以设计为导向的研究，对一户住宅的设计进行了更改，以逐步提高其LoC。结果表明，与初始设计（LoC = 0.20）相比，有可能将LoC翻倍至0.41，而不会增加LCC。此外，这些措施不需要对设计和施工过程进行根本性的改变。相反，它只需要用回收或生物材料代替原始材料，以及使用相对容易拆卸的建筑产品。结果还表明，提高圆形度会进一步导致产品成本的急剧增加，从而导致LCC的增加。这使其对建筑公司的经济吸引力降低。因此，我们建议从相对简单的措施开始，这已经可以使典型的单户住宅的当前流通水平提高一倍。
