Abstract
The ability to offer customisation has been considered as a competitive advantage for industrialised house building (IHB) companies. Product platform approaches have been acknowledged as one of the prominent ways to improve both internal and external efficiency. However, the use of traditional platform-based strategies does not suffice for the design of engineer-to-order (ETO)-based components in a building system. The purpose of this research is to test and evaluate how the reuse of design assets can be achieved by using a parametric modelling approach to support the design process of ETO-based components in a post and beam building system. This is an additional study using the design platform approach (DPA) that contributes to expanding the knowledge for designing ETO-based components. This research proposes a parametric design platform method developed by following an inductive approach based on the findings from a detailed study on bracket connection with a single case study in a Swedish multi-storey house building company. The proposed method offers flexibility in modelling ETO building components, facilitates design automation, and shows a 20-times improvement in the modelling process. This approach can be used in any building system with ETO-based components by identifying, formalising, and reusing connected design assets. A key finding is that the ETO components can be shifted towards configurable solutions to achieve platform-based design.

Parametric Design Platform to Support ETO Building Components A parametric design platform method is proposed to support the reuse of design assets associated with ETO-based building components in industrialised house building (IHB), thereby, fulfilling the purpose designers are modelling the building with the help of a computer-aided design (CAD) program
Summary
Industrialised house building (IHB) companies currently face challenges in balancing the degree of standardisation and customisation in their offerings [1,2]. They design and develop solutions by involving the customers resulting in unique buildings They are continuously faced with fluctuating requirements and small changes, such as added or removed building components or the placement of new components resulting in significant variation in both structural and technical perspectives. They often find it difficult to provide distinctive products to meet varying customer needs and at the same time to fulfil legal regulations, market demands, and production constraints [4]. ETO-based components are characterised by a growing degree of customised and unique nature where a design starts from scratch, and the level of variation creates a bottleneck in the design process commonly resulting in a high lead time and incurred costs [2,5]
