Core offering

Twinstone is a Dutch project and advisory bureau that provides consulting, research, resident participation, project management, and communication services to housing corporations, municipalities, and healthcare institutions. The firm focuses on mobilizing residents and organizations for sustainability in the built environment, including energy transition, climate adaptation, and neighborhood development. Its work is delivered through a modular methodology library delivered as project-based engagements.

Product overview

Twinstone is a project and advisory bureau specializing in mobilizing residents and organizations for sustainability in the built environment. Founded in 2010, the company operates as a consultancy rather than a technology product company. Their core offering consists of a portfolio of service methodologies and 'Bouwstenen' (building blocks) that address the 'missing link' in the energy transition: resident engagement and behavioral change. The approach combines strategic insight and social design with practical implementation, organized around four focus areas: sustainable/future-proof housing, social sustainability/cohesion, climate-resilient living environment, and sustainable mobility. The portfolio includes methodologies like the BewonersReis for mapping resident experiences, Draagvlak ophalen for building support, Energiecoaching for post-renovation guidance, and Bewonersbegeleiding during construction, alongside specialized tools such as the Ladder van Koeling (Cooling Ladder) framework and VURIS model for role clarity. Twinstone's offerings are structured as modular service components that can be combined per project, with a consistent focus on bridging thinking and doing.
