The paper establishes the need for a parametric design tool in contemporary tall timber construction, combining literature studies, expert interviews, and case study analyses. Findings reveal seven key challenges, including economic feasibility and fire safety, and explore techniques from recent tall timber developments. The conclusion highlights the potential of tall timber in reducing carbon footprint, balancing costs and sustainability, and introduces a parametric design tool serving as a decision-support system for architects, promoting the transition to timber as the main construction material in high-rise structures.
