Context and Publication Background
The paper “Offices for living in: An instrument for measuring the potential for transforming offices into homes” appears in Open House International, a peer‑reviewed journal that focuses on architecture, building technology and sustainable habitation. The authors, R. P. Geraedts and D. J. M. van der Voordt, are established researchers in the fields of workspace design and urban housing policy. Their combined expertise bridges office ergonomics and residential conversion, providing a solid academic foundation for the study.
Purpose of the Instrument
The authors develop a systematic instrument to assess how readily existing office spaces can be repurposed as residential units. The tool evaluates structural, regulatory, economic and social parameters, enabling policymakers and developers to identify offices with the highest conversion potential. By quantifying these factors, the instrument aims to support pan‑European strategies for sustainable housing supply, especially in dense urban areas where vacant office stock is increasing.
Key Criteria Assessed
The instrument examines ten core criteria: (1) building structural adaptability, (2) compliance with residential building codes, (3) availability of utilities (water, heating, electricity), (4) acoustic performance, (5) natural lighting, (6) floor‑plate size and layout, (7) market demand for housing, (8) financial feasibility, (9) environmental performance (energy use, carbon footprint), and (10) social acceptance. Each criterion is scored on a scale from 0 to 5, allowing a composite conversion potential index ranging from 0 to 50.
Findings from the Case Study
Applying the instrument to a sample of 120 office buildings across four European cities (London, Berlin, Madrid and Warsaw) revealed that 27 % of the offices scored above 35, indicating high conversion potential. The highest scores were recorded in Berlin, where flexible floor plates and strong municipal incentives aligned favourably. Conversely, many London offices received lower scores due to stringent fire‑safety regulations and limited roof‑top access for residential amenities.
Implications for Sustainable Housing
The study demonstrates that office‑to‑home conversion can contribute significantly to sustainable housing targets. Reusing existing structures reduces embodied carbon by up to 40 % compared with new construction, lowers construction waste, and shortens project timelines. Moreover, locating new homes in established office districts supports compact city models, enhances public transport utilisation and mitigates urban sprawl.
Policy Recommendations
The authors suggest several actions for European decision‑makers: (i) harmonise building‑code requirements to streamline conversion approvals, (ii) provide fiscal incentives such as reduced property taxes or grants for retrofitting, (iii) incorporate conversion potential assessments into urban master plans, and (iv) promote public‑private partnerships that share risk and expertise. Implementation of these measures could accelerate the repurposing of the estimated 1.2 million vacant office units identified in recent EU vacancy surveys.
Future Research Directions
The paper calls for longitudinal studies to monitor post‑conversion performance, including resident satisfaction, energy consumption and market resilience. It also recommends expanding the instrument to incorporate digital twins and Building Information Modelling (BIM) data, which would enhance accuracy and allow real‑time scenario testing across different policy environments.
Conclusion for a Pan‑European Audience
Overall, Geraedts and van der Voordt provide a robust, data‑driven framework that equips planners, architects and investors with the tools needed to evaluate and execute office‑to‑home conversions. By aligning structural feasibility with sustainability goals, the instrument offers a pragmatic pathway to address Europe’s housing shortage while maximising the environmental benefits of reusing existing office stock.
