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.

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.

Co-op Green Store, V4

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.

Paragraph 79 Passivhaus, County Durham

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, demonstrating how contemporary architecture can be regionally specific, historically influenced, and low carbon in construction and operation.

Greater Manchester Combined Authority 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.

Zero Energy and Zero Waste Food Hall

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.

Moat House Paragraph 55 Passivhaus Premium, Warwickshire

This singular Warwickshire home has been granted planning approval under Paragraph 55 of the National Planning Policy Framework before Moat House. It is pegged to be the UKs first Passivhaus Premium Zero Energy Home. 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.  

Off-grid Passivhaus Barn Conversion, Yorkshire

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. 

Edwardian Passivhaus Retrofit, Greater Manchester

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. 

Mid-Century Passivhaus Plus Retrofit

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).

Edwardian Retrofit with Passivhaus Extension, Chorlton, Manchester

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 what is now the office for Ecospheric has been meticulously sourced and thought out in order to reduce its carbon footprint and increase the comfort of occupants. From building materials to appliances and fixtures, every item 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. 

Low Energy Extension and Renovation, Manchester

This Arts and Crafts style house is located within the Chorltonville conservation area of Manchester. 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.

Infill plot Passivhaus Homes, Central London

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.

Passivhaus Detached New Build, South London

Ecospheric provided consultancy on M&E, ventilation, space heating and renewable energy generation for this new build Passivhaus family home. 

Passivhaus Retrofit, South London

This is one of a number of current Passivhaus retrofit projects which we are working on with London-based RDA architects. We have provided the PHPP modelling, M&E design, space heating design, construction detailing, and specialist moisture solutions on this project. 

Eco Renovation of a Victorian Terraced House, North London

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.

Rural Eco Home, Macclesfield

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.
