Balancing function and sustainability

Functionality ensures that a space serves its intended purpose, while sustainability focuses on minimising negative environmental impacts. In today's world, where climate change and environmental degradation are pressing issues, designers must prioritise sustainability in their work. However, this cannot come at the expense of functionality.

A truly sustainable design should be both functional and environmentally responsible, seamlessly integrating these two aspects to create a product or space that meets the needs of users while also contributing positively to the planet. Achieving this balance requires creativity, innovation, and a deep understanding of both user needs and environmental considerations.

We are committed to a sustainable future and to improving the social, economic and environmental wellbeing of our communities. As a significant contributor to waste and emissions, Chalk recognises the need for the construction industry to reduce its impact, and importantly, better understand the part it needs to play in protecting the natural environment.

At our inception in 2015, we committed to the positive enhancement of the environments in which we operate and to act with sensitivity to the world around us for future generations.

We will always seek to uphold our vision and values for a cleaner world, through, smart design, the use of sustainable materials, and the application of modern construction methods.

Passive Haus Schools

We take an active approach to passive design by taking a fabric-first approach. Our passive, energy-efficient homes are sustainably designed to consume minimal energy for heating and cooling. Passive homes achieve this by relying on natural sources of heat, insulation, and ventilation to regulate temperature within the building, rather than relying on conventional heating and cooling systems.


Passive Haus Schools are built to strict energy-efficient standards, which typically include features such as high-performance windows, thick insulation, and an airtight building envelope. As a result, passive homes are not only environmentally friendly but also provide superior comfort and indoor air quality.


Our experienced architects and builders work closely with clients to create custom homes that meet their unique needs while adhering to strict standards and exceeding standard building regulations. From initial concept design and developed technical design, to final construction, we strive for excellence in every aspect of our work, including full custody of design. Our client’s vision is never watered down with regular check-ins to review project affordability and environmental impact at each milestone.

Carbon Neutral

Carbon-neutral design refers to the holistic approach of designing and building structures that result in net-zero carbon emissions in both operation and construction, while considering every aspect of a project’s lifecycle. This is achieved through responsible material specification, modern methods of construction, operational systems, the use of innovative technologies, and end-of-life disposal or recycling.


We understand that there is a climate emergency and want to ensure we make a positive contribution to addressing this. The goal of carbon-neutral design is to minimise the impact of buildings on the environment by reducing their contribution to climate change while creating comfortable, functional spaces for people to live and work in.


Launched at Cop26 in 2021, and in association with the Department for Education and the Construction Innovation Hub, GenZero is a blueprint for ultra-low carbon school environments. As a part of this initiative Chalk and the DfE have considered how specially designed, ultra-low carbon furniture, fittings and equipment can contribute to the fight against the climate crisis, and have developed a prototype facility.


GenZero also promotes education about sustainable living in schools and universities. By teaching young people about sustainability, we can create a culture that values environmental stewardship and takes action to protect our planet. Its aim is to help young people understand the impact of their actions on the environment and provide them with tools to make more sustainable choices.


By focusing on finding innovative solutions to today’s environmental challenges while inspiring positive change in our schools and communities, we can work towards creating a brighter future for GenZero and all future generations.

Circular Economy

As part of our sustainability commitment, we are passionate about promoting a circular economy that prioritises sustainability and resource efficiency. The circular economy is an economic model that aims to minimise waste and maximise the use of resources by keeping materials in use for as long as possible.


It is based on the principles of designing out waste and pollution, keeping products and materials in use, and regenerating natural systems. By shifting from a linear “take-make-dispose” model to a circular one, we can create a more resilient, equitable, and sustainable future for all.


Our team is dedicated to helping clients transition to a circular economy through the Cradle to Cradle (C2C) design framework, and through the procurement of innovative solutions that reduce waste, increase resource efficiency, and promote sustainable practices.
