Services
Sustainable Architecture
We create low-energy buildings that combine environmental responsibility with architectural excellence. Our approach integrates natural materials, energy modelling, and passive design principles to reduce carbon footprints while enhancing comfort. Specialising in period property retrofits and new builds, we deliver tailored solutions that meet rigorous sustainability standards like Passivhaus and AECB EnerPHit. Our process ensures technical precision without compromising aesthetic quality.
House Extensions
We design contemporary extensions that respect original architecture while modernising functionality. Our light-filled garden rooms and roof extensions use breathable materials to improve thermal performance. Each project balances spatial innovation with planning constraints, creating seamless transitions between old and new structures while enhancing energy efficiency and natural light.
Retrofit Strategy
Our whole-house retrofit approach addresses insulation, airtightness, and ventilation to transform outdated properties into high-performance homes. We specialise in phased upgrades for solid-wall constructions, combining PHPP energy modelling with fabric-first solutions. This reduces energy bills by up to 90% while preserving architectural heritage through meticulous detailing and material selection.
Interior Design
We craft interiors that prioritise wellbeing through natural materials, ergonomic layouts, and strategic lighting. Our bespoke joinery solutions maximise storage while maintaining aesthetic coherence. By integrating architectural elements with functional design, we create calm, intuitive living spaces that reflect occupants' lifestyles and values through sustainable material choices.
3D Visualisation
Our advanced visualisation tools create photorealistic renders and interactive walkthroughs to clarify design intent. This technology supports informed decision-making during planning stages and helps clients experience spatial relationships before construction begins. We use these models to test daylighting strategies, material selections, and construction details for optimal outcomes.
