Twilight Talks

The Green Register's early evening talks supported by Ecomerchant: together promoting ethical, healthy sustainable building materials.

On the second Monday of each month The Green Register brings you our Twilight Talks - a relaxed and informal string of events on sustainable building matters to complement our regular training topics.

Each one-hour event is FREE of charge and features short talks from one or more speakers. With Q&A and discussion sessions throughout, everyone is invited to be part of the conversation. We hold Twilight talks at 5-6pm, in the sweet spot between work and dinner – so join us to nourish the mind before replenishing the body!

The Greenest House

Greenest House offers an alternative to demolition by upgrading and retrofitting existing terraced homes - a typology ubiquitous across UK cities. By increasing the usable space within these homes and converting them into multiple high-quality dwellings, Greenest House delivers affordable, energy-efficient housing while preserving community fabric. 

Our belief is simple: the greenest house is the one that already exists. By extending and renewing these cherished buildings, we can double housing capacity, drastically reduce energy consumption, and keep neighbourhoods intact. 

Much of the UK’s existing housing stock is outdated, poorly insulated, and energy-inefficient - with only 29% of UK homes achieving an EPC rating of C or above. Alarmingly, 6.7 million people live in fuel poverty. Despite this, the trend toward demolition and rebuild continues to displace communities, waste valuable resources, and contribute to the climate crisis. 

The Greenest House initiative reinvests value unlocked through thoughtful redevelopment directly into the building itself. Upgrades include enhanced insulation, triple glazing, solar panels, and air source heat pumps. This model can reduce a home’s space heating demand by up to 90%, cutting both carbon emissions and energy bills. Furthermore, it enables residents to access benefits such as reduced council tax and green mortgages. Too often, the social and environmental costs of poor housing are ignored. We believe in a future where economic, social, and ecological sustainability go hand in hand.

About the Speakers

Erika Suzuki (BEng MEng DipArch MArch ARB) and Anders Strand Luhr (MArch ARB RIBA) met while studying at Bartlett School of Architecture (UCL). Curious about the potential of architecture to improve lives for clients and communities as well as for those who practice it, they established Office Ten to cement their vision for a better way of life.  

The team combines their practice with research through teaching at the Architectural Association and University of Greenwich, where they have established a design unit focused exclusively on working with existing buildings.  

In 2024, ‘Apartment with a Mezzanine’ was shortlisted for the Don’t Move, Improve! Award and exhibited at the NLA’s London Centre. In 2025, the firm will exhibit their ‘Greenest House’ project at the Venice Biennale of Architecture, as part of the “TIME SPACE EXISTENCE” exhibition.
