Planning permission has been granted for the next stage at Adelphi Village, a residential development that will deliver 263 new homes, to one of the zones that make up the Crescent Salford Masterplan.

The approval marks an important step forward for the scheme, which will transform a brownfield site on Peru Street into a sustainable new neighbourhood, providing a mix of high-quality market and affordable homes designed to meet the needs of the growing city. Construction is expected to begin in summer 2026.

The £2.5bn, 252-acre Salford Crescent Framework is being delivered by the Crescent Partnership, which includes Salford City Council, the University of Salford and ECF. ECF is a joint venture between Muse, Homes England and L&G.

The 263 new residential units will be delivered as a mix of apartments and duplexes arranged across three six-storey blocks (ground + 5-storeys).

Plans for this new residential neighbourhood include communal spaces; green spaces; dedicated cycle parking; and high-quality accessible homes with provision for disabled parking with EV charging facilities.

Building Services Engineering Strategy

As the Building Services Engineering Consultant on the project our key duties include:

• Technical review and appraisal of MEP strategy options and requirements to achieve Passivhaus Certification
• Technical review and development of plant space requirements & distribution routes
• Provide MEP design input into the PHPP assessment for certification
• Coordination of existing and new incoming utilities services to suit programme and phasing of this phase and the neighbouring developments.
• Building Regulations Part L Vol 1&2 Design Stage Compliance Assessments
• Dynamic Simulation Modelling & Limiting Overheating Analysis for Compliance with Building Regulations Part O
• Ongoing site inspections & reporting during the construction period

We’re pleased to be working alongside Buttress, Chroma, Clancy Consulting, Project Four, Max Fordham, Re-form Landscape Architects, CBRE, DFC and GWB Consultants on the project design team.

Completed and handed over in July 2026, Willohaus has welcomed its first residents.

The new build residential development delivers a total of 100 affordable and sustainable Passivhaus ‘Classic’ certified apartments on Peru Street in Salford. The part five, part six-storey building comprises a mix of one- and two-bedroom homes, including a proportion of accessible apartments at ground floor.

Willohaus is the second Passivhaus-certified residential scheme brought forward by the ECF in Salford, following the success of Greenhaus on Chapel Street, which completed in 2024. Salford housing association Salix Homes is the housing partner for Willohaus and owns and manages the new homes.

It marks the first completed residential development within Adelphi Village, part of the wider £2.5bn Crescent Salford masterplan.

Building Services Engineering Strategy

Hannan Associates provided the role of Building Services Engineering Consultant on the design team, working in collaboration with the Passivhaus Designer to develop the most effective design Strategy. Our duties included:

• Utilities services coordination
• Technical review and development of MEP strategy options and plant space requirements to achieve Passivhaus Certification
• Provide MEP design input into the PHPP assessment
• Develop a spatially coordinated MEP design
• Building Regulations Part L Compliance Assessments
• Building Regulations Part O Limiting Overheating Analysis
• Ongoing site inspections & reporting during the construction period
• Witnessing of the tested & commissioned MEP installations

The primary focus for buildings designed to achieve Passivhaus standards is to employ passive design measures to drive down energy demand. Further to this, the MEP services design is optimised to reduce operational energy intensity associated with the fixed building services. 

The result of which is to provide an enhanced and more comfortable internal environment for residents, but importantly can reduce energy bills by typically 60%, up to a possible 90%, which offers a significant benefit to the resident.

To achieve full certification; the design and construction of the buildings are independently tested and verified prior to occupation.

Hannan Associates worked alongside Chroma, Buttress Architects, Clancy Consulting, Max Fordham, Re-Form, CBRE, Atkins Realis and DFC, in conjunction with main contractor Eric Wright Construction and MEP Contractor Ameon Building Services

ECF and Salford Crescent

Willohaus is part of ECF’s wider £2.5bn regeneration scheme transforming the area of Salford Crescent.

The masterplan contains commercial, retail, residential buildings and enhanced green spaces creating a new and vibrant destination for people to live, work and relax.

ECF is a joint venture between Muse, Legal & General and Homes England. Development partners for the masterplan also include Salford City Council and the University of Salford.

What is Passivhaus

Passivhaus is an international energy standard, originating in Germany, which emerged in the 1990’s and is regulated by The Passivhaus Trust. Passivhaus is typically applied to residential developments, however commercial buildings can also achieve certification. There are 3 ‘traditional’ levels of certification: Classic, Plus and Premium, with options for LEB (Low Energy Building) classification and a retrofit standard also available.

Certification is achieved by employing the 5 foundational principles of Passivhaus, summarised below:

1. Superior Insulation: Continuous, high-performance insulation
2. High-Performance Windows: Triple-glazing and insulated frames
3. Airtightness: Continuous sealing of the building envelope to prevent drafts.
4. Thermal Bridge-Free Design: Careful detailing to eliminate thermal interfaces where heat can escape.
5. Mechanical Ventilation with Heat Recovery (MVHR): Certified, highly efficient systems that supply constant, fresh filtered air while extracting waste heat from exhaust air

Why Design a Passivhaus Project? 

Benefits of designing a Passivhaus Project include; improved thermal comfort, improved indoor air quality & reduced energy demand, which results in lower running costs and increased resident satisfaction.

A building designed to achieve Passivhaus Certification will typically outperform current Part L requirements and will more closely align with the  Future Homes Standard and LETI targets. Passivhaus design can result in energy savings of between 60 – 90% for the end-user, with typical cost uplift of between 2-8% depending on the nature of the scheme.
