Sustainability

Reducing carbon. Improving comfort.

Creating energy-efficient places that balance environmental aspirations with everyday needs.

The transition to net zero calls for buildings that use less energy and generate less carbon throughout their life. Architects play a key role in this, shaping decisions about reuse, materials, building fabric and energy systems from the earliest design stages.

At BTP, sustainability is embedded in our approach to design. We help clients balance energy performance, carbon reduction, comfort, compliance and cost to develop solutions that are both ambitious and deliverable.

 

Our in-house expertise includes Passivhaus design, SAP and energy assessments, and PAS 2035 retrofit consultancy. Solutions are tailored to meet Building Regulations, Passivhaus standards or wider net-zero ambitions, depending on each client’s priorities and budget.

For new buildings, we apply fabric-first principles, assess overheating risk and integrate low-carbon technologies where appropriate. For existing buildings, our PAS 2035 specialists develop coordinated whole-house solutions that improve energy efficiency, reduce fuel poverty and avoid unintended consequences.

BTP is committed to the RIBA 2030 Climate Challenge and follows a carbon management plan aligned with the UK’s net-zero ambitions.

    BA(Hons), M.Arch, RIBA, ARB

    I’m an architect with specialist experience in housing and heritage projects, with a particular focus on fire safety and cladding remediation. I qualified in 2015 and joined BTP in 2017, following roles in Singapore and Sweden working on public buildings, BIM management and accessible design.

    I am qualified as a Certified European Passive House Designer, a RIBA accredited Conservation Architect, and became one of the first Architects to be listed on the RIBA Principal Designer Register for Higher Risk Buildings (HRBs).

    Outside work, I like to keep fit with running, hiking, weightlifting, skiing and rock climbing. Travel and adventure are a big part of my life, from completing the Inca Trail and climbing Kilimanjaro to running my first (and probably only) marathon on the Great Wall of China.

    I joined BTP in 2008, qualified as an Architect in 2013, and progressed to Director in 2017. Over my career, I’ve built extensive expertise across the full range of design criteria for housing, later living, and care environments, including HQI, DQS, Lifetime Homes, HAPPI, NDSS, and Building Regulations accessibility standards.

    Sustainability is a core part of my professional focus. I am an accredited Energy Assessor for both new-build and existing homes (OCDEA / DEA) as well as a certified Home Quality Mark Assessor and PAS2035 Retrofit Designer / Assessor. Within BTP, I lead many of our sustainability initiatives; developing strategies to help clients realise their ambitions, meet zero-carbon targets, and align with the Future Homes Standard.

    Since 2013, I have also played a key role in enhancing BTP’s BIM (Building Information Modelling) capability. I have achieved multiple BRE qualifications, including ISO 19650 accreditation, enabling me to manage BIM processes and workflows effectively across our projects.

    In 2024, I joined the RIBA Principal Designer Register, gaining Principal Designer status with High‑Risk Building (HRB) expertise for both CDM and Building Regulations following rigorous training and examination. I now act as Building Regulations Principal Designer across a range of new‑build and refurbishment schemes, providing trusted guidance to clients and development teams.

    My advanced knowledge of BIM, sustainability, and the Building Safety Act also sees me deliver regular training, CPD sessions, and workshops for Registered Providers and contractors.

    I joined BTP as an architect in February 2021, bringing eight years’ experience at a large commercial practice in Manchester. I was promoted to associate in x and became a Director in 2023. My background spans masterplanning and large-scale residential and commercial projects across the UK, alongside projects throughout Asia, including a monastic school in India and major masterplans in China.

    At BTP, I’ve developed my knowledge and experience in conservation and refurbishment projects across the country, most recently helping convert a listed building in Holyhead, Anglesey, into apartments. I’ve also developed a particular specialism working on high-rise recladding projects across Greater Manchester.

    I am a Certified Passivhaus Designer with a focus on refurbishment and sustainability and have a keen interest in how we can live sustainably whilst minimising the impact on the environment.

    Outside work, I love cooking, having spent my early years working as a chef in a family restaurant. I’m also a qualified drone pilot and enjoy combining travel and hiking with aerial photography, most recently in the Dolomites and Norwegian fjords. Other interests include running, music and keeping up with the latest technology.
