Designing for tomorrow, today.
Proud contributor to the UK Net Zero Carbon Building Standard, helping shape the benchmark for sustainable design nationwide.
Sustainability isn’t a target – it’s the way we design.
We help clients move from ambition to action with practical strategies that reduce carbon, cut energy use, and future-proof estates.
Our team works across sectors, from heritage buildings to new developments, bringing technical expertise, regulatory insight, and creative solutions to every project.
What we do best
We deliver net zero outcomes through an integrated, data-driven approach:
Net zero strategies – clear roadmaps built on robust building and estate data.
Decarbonisation planning – from fabric-first upgrades to low-carbon heat.
Embodied carbon analysis – early-stage modelling and whole-life assessments.
Circular economy principles – reuse, flexibility, and material passports.
Certification & compliance – Passivhaus, BREEAM, NABERS, WELL, LEED, and planning-stage energy statements.
Our promise
Our interventions help clients prioritise interventions, secure funding, and achieve measurable carbon reductions.
01
Passivhaus expertise
We are proud to lead some of the UK’s most ambitious Passivhaus projects, from low-energy housing to high-performance schools and workplaces. Passivhaus isn’t a badge, it’s a proven methodology that cuts energy demand, improves air quality, and builds resilience.
Our certified consultants support projects at every stage: PHPP modelling, fabric specification, airtightness, MEP integration, and certification.
02
Retrofit & existing buildings
Most of the buildings that will stand in 2050 are already here. Retrofitting them is key to decarbonisation.
We design retrofit strategies that improve comfort, reduce bills, and tackle overheating while avoiding the carbon cost of demolition. From social housing to historic estates, our expertise covers:
- PAS 2035 Retrofit Roadmaps
- EnerPHit & AECB Standards
- Moisture and condensation risk analysis
- Energy audits and phased decarbonisation plans
03
Whole life carbon & circular economy
Operational energy is only part of the story. We also assess carbon across the full lifecycle of buildings — from materials to demolition.
Our specialists deliver whole-life carbon assessments and circular economy statements to GLA and UKGBC standards, ensuring designs are resilient, adaptable, and resource-efficient.
Design for performance
Meeting compliance doesn’t guarantee performance. That’s why we test designs against real-world outcomes using operational energy modelling and NABERS UK assessments.
By integrating our sustainability and MEP teams, we close the performance gap — so buildings operate as efficiently as they were designed.
