Our Developments and Projects
Ecospheric is proud to lead the market in sustainable development. Our Zetland Road Passivhaus is the first EnerPHit Plus home in Europe, the Sorting Office is aiming to be the first zero waste and zero energy food hall, and Shedbarn is an off-grid Passivhaus conversion of a 300-year-old barn for group accommodation. We have a decade of experience advising architects, builders, planners and homeowners on sustainable retrofit and creating the very best in building performance. We intend to spend the next decade transforming buildings, pushing boundaries and growing influence to make the industry changes we so desperately need.
Grade II* Elizabethan Retrofit and New Build Passivhaus Development
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. The project will also see the development of 5 new build Passivhaus family homes on 2 acres of adjoining land.
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.
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 79 Arts & Crafts House
Ecospheric is currently working on a 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, features multiple buildings, indoor swimming pool, and outdoor ponds and swimming ponds. The design of this house will employ locally sourced materials, innovative design and mechanisms to maximise energy savings.
Paragraph 79 Pre-Georgian House
Ecospheric is currently working on a project in Hampshire’s Test Valley which will see the unique integration of energy and biodiversity between a manor house and farmstead. The new-build manor house will be designed in a pre-Georgian style and is aiming for Passivhaus Plus certification or similar. The house will incorporate reclaimed materials from existing buildings, integrate with the wider farmstead to share renewable energy generation, benefitting from the economies of scale of multiple units.
Zero Carbon Supermarket
Ecospheric is supporting Co-op in the creation of a new 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 1960's 5-bedroom solid concrete home in London is being retrofitted to Passivhaus Plus and NZEB standard. The building will be designed with renewable energy generation including a fully integrated PV solution. Energy management is designed to maximise self use (utilisation factor).
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 EnerPHit
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.
Paragraph 55 Zero Energy Home
This singular Warwickshire home has been granted planning approval under Paragraph 55 of the NPPF. The key design concept for this project revolved around a trombe wall which acted as a giant heat store to buffer the internal living environment whilst simultaneously integrating with advanced services capable of reworking and distributing this energy around the dwelling.
Low Energy Modern Extension
The proposal was to completely face-lift and modernise the rear of the property to make the most of the unparalleled view of Chorlton Ees Water Park whilst adopting new timber framing techniques and a whole house low energy retrofit approach. The original design attempted to incorporate passive heat distribution techniques to compensate for the overheating potential created by the large expanse of glazing on the south facing facade.
Low Energy Timber Framed Home
This home was designed to reflect the rural setting, with a shape referencing a barn or farmhouse. Slate roofs and charred timber cladding were used as well as high performance windows to maximise solar heat gain for the home.
This affordable, compact timber framed build has extremely high levels of insulation and airtightness combined with MVHR to guarantee a healthy living environment. The house benefits from on-site energy generation and an allotment to provide the occupiers with a truly sustainable home.
Victorian Terraced Retrofit
This is a contemporary remodelling of a Victorian terraced house in London. Environmentally friendly, breathable roofing materials were used on the ground floor extension. Durable pre-fossilised timber cladding was used on the extension as it requires no paint; therefore, removing the use of petrochemicals and short maintenance cycles. Large triple glazed windows were added to maximise solar heating for the house, reducing the need for central heating.
Arts & Crafts Retrofit
The retrofit of this 1909 home was designed to demonstrate pioneering low energy building technologies and materials. Completed 10 years ago and achieving an 81% decarbonisation, every aspect of this home - from building materials to appliances and fixtures - has been chosen with sustainability in mind. A timber-framed Passivhaus level extension has been added to the rear of the home, with glazed mono-pitch roof to capture energy alongside thermal mass components to store the heat. This is the first house to utilise Passivent's iHybrid whole house mechanical ventilation heat recovery (MVHR) system. The first installation of Aerogel (Spacetherm) External Wall Insulation. The first ever integrated solar powered rainwater harvesting system.
