Sustainability

As is the case for every project we undertake here at Yiangou, our approach to sustainability, enhancement of biodiversity, health and wellbeing are integral to our design philosophy and process.  By prioritising these values, we aim to create homes and places that foster a deep connection between people and their built and natural environment, contributing to a more sustainable future for our clients and the public for generations to come.  

Design that Endures

We value the importance and preservation of our historic built environment.  Retaining existing buildings instead of building new is inherently sustainable, and we look to upgrade the heritage assets we have the privilege to work on, by integrating project-specific and sensitive adaptations which will ensure the buildings have a place for future generations. 

This philosophy follows through to our new build project, where we prioritise longevity by aiming to create buildings that not only physically endure the test of time, but are of a quality and beauty that future generations will want to cherish and preserve, thereby maximising the return on the carbon cost of construction.

Material Selection

Our approach begins with holistic, project and site-specific analysis.  We adopt a fabric-first strategy to achieve high performing buildings, through considered material choices, robust technical detailing and wherever available our material selection includes low carbon alternatives. 

We use industry recognised carbon calculation tools to interrogate the embodied carbon content of the make up of our buildings and fine-tune this to strike the balance between the upfront carbon cost and the future robustness and thermal performance of each building element. We look to specify local materials, worked by local craftspeople which not only enhances a sense of local character and place but also minimise the carbon cost of transportation.  

Greener Technologies

We consider the environmental impacts of our projects throughout their life span, not just during the design and construction phases.  Working alongside energy consultants we are actively promoting to decrease dependency on fossil fuels by examining the potential for energy generation across our project sites.  Where suitable we also encourage a shift from a car-centric environment by providing the necessary facilities to encourage sustainable transport choices by the end user.  

We work closely with specialist landscape consultants to uphold and enhance the biodiversity value of the sites we work on, which includes exploring water management potentials. This not only benefits project but has positive impacts on the wider surrounding environment.  

Studio Considerations


When compared to the resource intensity of construction, the environmental impact of the architectural design process itself is minimal. This doesn't stop our team from expecting the practice to follow the same principals as we follow on our projects.

We undertake annual reviews of the studio's carbon impact. We aren't carbon neutral yet, but we do compare well against other business of our size and our per-capita footprint of c. 1.6T CO2e (including business travel and commuting) is coming down. We continue to look for ways to improve further and have passionate members of the Green Committee regularly bringing ideas forward.

We are conscious that cloud services can come with significant carbon overhead which is one of the factors in our primarily "on premises" approach to IT services, and in partnering with providers that offer best in class operational carbon measurement and mitigation. We continue to give preference to carbon neutral and B-Corp suppliers within our procurement process, and like to work with businesses that share our ethos.

When we do print for internal use, we follow rigorous recycling policies. These have been extended to include waste materials from 3D printing which are sent away for re-manufacture. I'm proud that we're chasing these marginal gains and making sustainability a factor in practice wide descisions.

Sustainability and Planning Opportunities

Whilst we always work closely with our clients to set sustainable design priorities, weighing against costs and other factors, there are occasions where the planning process will play a significant role.

For example, these estate workers' cottages would not have received planning approval had it not have been for environmental modelling that demonstrated their long term energy consumption and carbon impact.

There are other situations where the Practice makes use of paragraph 80 of the National Planning Policy Framework. This allows for new dwellings in open countryside under very specific circumstances.

These designs have to meet the legal definition of "truly outstanding" and positively impact the immediate surroundings. Bringing in environmental consultants early in these projects is essential, and we can help assemble and manage the team of professionals that an application like this requires.

Following physical testing, these cottages are carbon neutral in operation

As a Chartered Practice, we are committed to the goals of the Royal Institute of British Architect's programme of carbon reduction within projects. The aim of the scheme is measure and improve embodied carbon, operational energy and potable water use.

The practice is a signatory to the Architects Declare project, highlighting the loss of biodiversity and the changing climate and its risks to the built environment.

We have joined more than 1400 practices in stating our commitment to push for systemic changes to how buildings are planned, designed and built and to strive beyond net zero towards regenerative architecture.

We have been members of The Green Register since 2013, demonstrating a long term commitment to enviromental matters and best practice, especially in the context of conservation projects. Ensuring that our historic properties are managed and renewed for future generations is a critical part of creating a truly sustainable future.

We run a longstanding Environmental Committee, formed of individuals from across the practice, who are passionate about research into emerging technologies, products and systems. The dedication and inquisitive nature of this group contributes to the continued sustainability improvements across all our projects which in turn is conducive to our ongoing optimism and commitment to combat climate change.
