Our Developments and Projects
Ecospheric is proud to lead the market in sustainable development. Our in-house developments include Lymm Hall, a research hub for low carbon retrofit in heritage and listed buildings; Zetland Road Passive House, the first EnerPHit Plus home in Europe; the Sorting Office zero waste and zero energy food hall; and Shedbarn, an off-grid Passivhaus conversion of a 300-year-old barn for group accommodation. We use each of our developments as a test-bed to trial new approaches to sustainable design and building and share that expertise with our clients - architects, builders, planners and homeowners - delivering the very best in building performance.
Countess of Chester Women & Children's Hospital
A £110m Women and Children's building proposed for the Countess of Chester Hospital will be trialling the new NHS Net Zero Carbon Building Standard. Ecospheric will be taking on the role of Net Zero Carbon Coordinator which is a cross functional position to enable holistic whole life decarbonisation of every aspect of the building. The project will aim to further the hospital trust's goals as set out in its Going Greener Strategy.
1940's era Stone EnerPHit
Ecospheric is supporting the EnerPHit retrofit of this 1940's era stone manor house in Sheffield. Ecospheric has carried out PHPP calculations and design, dynamic simulation modelling, overheating and daylighting analysis, architectural and technical detailing support, structural strategy support, and on-site quality support.
Passivhaus Art Studio and Cafe
Goldfinch Create and Play is a bright and airy 2-storey timber framed Passivhaus cafe and art space in Bristol's Westbury-on-Trym neighbourhood. Ecospheric supported SEB + FIN Architects with Passivhaus design for this certified cafe, the first in the UK. The project achieved a very high level of airtightness using cellulose insulation and is powered by 21 solar panels.
The UK's first Passivhaus certified cafe
1880's Conservation Area EnerPHit
This retrofit of a Victorian townhouse in a London conservation area features an internal wall insulation strategy which
allowed for EnerPHit levels of thermal performance and airtightness while also preserving the heritage features of the building.
5 Single Family Passivhaus Premium Homes
A development of five new building single family dwellings designed to meet Passivhaus Premium performance. These 5-bedroom luxury homes are designed to have minimal embodied and operational impact, and will produce enough renewable energy on-site to power all household and site needs, including appliances, lighting, space heating/coooling, domestic hot water and ventilation. Permission for planning approval is currently being sought. If approved, this project would be the first development of multiple Passivhaus Premium certified dwellings on one site.
Modernist EnerPHit Plus
This 1960's 5-bedroom solid concrete home in London has been retrofitted to EnerPHit Plus and NZEB standard. The building is designed with renewable energy generation including a fully integrated PV solution. Energy management is designed to maximise self use (utilisation factor).
Finalist for the UK Passivhaus Trust Award 2023
Low energy replacement farm workers dwellings
Ecospheric provided a comprehensive package of support for this project in Hampshire’s Test Valley, which included pre-planning sustainability advice for both a Paragraph 80e country house designed to meet Passivhaus Plus certification as well as low energy design for two workers cottages. The workers cottages obtained planning consent in May 2023.
Historic Brick Workshop Turned EnerPHit
This 19th century brick workshop was used as an architecture studio before being retrofitted in 2021 into a certified Passivhaus detached family home. Ecospheric supported London-based RDA architects with PHPP modelling, M&E design, space heating design, construction detailing, and specialist moisture solutions on this project.
First certified EnerPHit conversion to residential retrofit
Grade II* Elizabethan Retrofit
This 400-year-old manor house sits on a property dating from the Domesday Book. Lymm Hall is a Grade II* listed historic building with a number of protected monuments on the grounds including a dry moat and one of only two remaining cock-fighting pits on a private residence. Ecospheric is developing this property as a test bed for sustainable retrofit on traditional stone and brick buildings.
Victorian-era EnerPHit Plus
These two semi-detached homes are Europe's first Passivhaus Plus retrofits. This exemplar project has achieved a 95% reduction in space heating demand with zero energy bills. The project goes beyond Passivhaus by minimising embodied carbon and using only natural building materials to achieve a petrochemical-free, breathable building fabric. Incorporating 8 world first technologies/methodologies, this was truly a laboratory for domestic retrofit.
Awarded the International Passive House Association Living Comfort Prize 2021, ASBP People's Prize 2022, and Shortlisted for the AJ Retrofit Awards 2019
GMCA Retrofit Accelerator
Greater Manchester is setting out to understand how the region can upgrade existing housing stock in order to achieve its net zero carbon target by 2038. As part of our commitment to carbon reduction, Ecospheric is providing technical advice for this project which aims to deliver up to 61,000 energy efficient residential renovations.
Paragraph 80e Arts & Crafts House
Ecospheric supported the sustainability strategy and Passivhaus design for this new-build Arts & Crafts style house in the Cotswolds which is aiming for Passivhaus Premium - producing far more energy than it would consume. This substantial country house, situated on a farmstead, would feature multiple buildings, indoor swimming pool, outdoor ponds and swimming ponds. The design of this house will employ locally sourced materials, innovative design and mechanisms to maximise energy savings.
Zero Carbon Supermarket
Ecospheric is supporting Co-op in the creation of a new Model Green Store, which will provide a blueprint for all newly built Co-op supermarkets. Co-op have made a pledge to achieve zero carbon performance across the Co-op group. All aspects of sustainability are being considered; from foundations to building fabric and a plethora of renewable and energy efficient technological solutions. These measures will transform the face of supermarket design, construction, and operation.
Off-grid Passivhaus Barn Conversion
This 300-year-old barn in the Yorkshire Dales National Park will be retrofitted to meet Passivhaus certification. The building will be powered through renewable energy generation, independent from the national grid. The former barn will be used for group accommodation. This is part of a wide strategy to find diversified use for derelict agricultural buildings in the national park in an effort to prevent further loss of heritage assets whilst enhancing the natural landscape.
Zero Energy, Zero Waste Food Hall
Levenshulme, Manchester, UK
Levenshulme's former Royal Mail sorting office is pegged to be the world's first zero energy, zero waste food hall, grocers/deli and brewery. The retrofit will sympathetically retain period features of this local landmark while upgrading both the building fabric and introduce a novel energy generation and storage solution. The solar PV array is already producing enough power to make the construction process carbon negative. There will be seating for approximately 110 people with additional beer garden seating for 50 more.
Infill plot Passivhaus Homes
These two ultra compact new build Passivhaus homes present unique challenges built against existing buildings and right up to boundary lines. Ecospheric provided the Passivhaus modelling, thermal bridge modelling, DHW, space heating, moisture and mechanical ventilation design for this project along with foundation and party wall solutions.
This new-build Passivhaus detached home is designed with reference to the Arts & Crafts style of the neighbouring buildings. Ecospheric provided consultancy on M&E, ventilation, space heating and renewable energy generation for this Passivhaus family home constructed using cross laminated timber.
Paragraph 79 Pele Tower Passivhaus
County Durham, UK
A unique family home which takes inspiration from the historic fortified houses (Pele Towers) and solitary stone barns of the North East. This new build Passivhaus will be constructed using locally quarried natural stone, sustainably sourced timber, and solar PV roofing slates. Planning permission has been granted under Paragraph 79 of the National Planning Policy Framework to deliver a Near Zero Energy (NZEB) and certified Passivhaus. The house is on track to set a new standard for rural sustainable building design in Durham.
Edwardian Stone Retrofit to AECB Standard
Greater Manchester, UK
With stunning views across the Goyt Valley, this 7-bedroom Edwardian-era stone mansion will be retrofitted to EnerPHit standard. The complex existing fabric and strict conservation limitations make this an exciting retrofit challenge. This project involves developing a fully internal intervention programme with very complex moisture considerations. This Passivhaus retrofit may provide a blueprint for conservationist issues for period properties and open the door for retrofitting in conservation areas and listed buildings.
