Collaborative Design Advisory Role.
An embedded partner for architectural practices and developers.
We often act as the sustainability arm for established architectural practices, providing the specialised data and strategic oversight needed to win bids and deliver high-performance buildings.
Embedded Strategy: We sit within your project team as a discrete advisory partner, providing real-time feedback on the environmental impact of design decisions.
Framework Alignment: Guiding projects through the requirements of BREEAM, Passivhaus, or the RIBA 2030 Climate Challenge.
Materiality Deep-Dives: Researching and sourcing low-carbon materials that match your aesthetic and performance requirements.
Heritage & Listed Building Retrofit.
Sympathetic sustainability for historically significant fabric.
Retrofitting a listed building requires a level of nuance that standard consultants often lack. We combine our architectural background with a deep understanding of historical building fabric to improve thermal performance without compromising heritage value.
Technical Retrofit Strategy: Advising on the "fabric-first’ approach for heritage assets, focusing on breathable insulation, glazing solutions, and moisture management.
Planning for Listed Assets: Navigating the delicate balance between modern energy requirements and the statutory protections of heritage status.
Authentic Restoration: Ensuring that every sustainability measure—from heating systems to window details—respects the historical narrative of the building.
De-risking the planning process with technical authority.
We specialise in producing the technical documentation required to clear complex planning hurdles in London and across the UK. We move beyond checkbox compliance to create robust strategies—from residential conversions to commercial developments—that align with your design vision while satisfying Local Planning Authorities.
Planning Compliance: Drafting comprehensive Sustainability and Energy Statements tailored to the specific requirements of the London Plan 2026 and Local Authority SPDs.
Carbon Calculations: Providing precise Whole Life-Cycle Carbon (WLC) data using Life Cycle Analysis (LCA) assessments. We measure and mitigate embodied carbon to justify material choices and ensure alignment with the UK Net Zero Carbon Buildings Standard.
Circular Economy Statements: Integrating circular design principles to ensure your project meets emerging standards for resource efficiency and material recovery.
Technical Performance: Delivering Part L (SAP) baseline modelling and Part O Overheating Risk Assessments to ensure compliance without compromising architectural intent.
