PROJECT OVERVIEW

Completed in July 2026, Willohaus, 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  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.

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:

o Utilities services coordination

o Technical review and development of MEP strategy options and plant space requirements to achieve Passivhaus Certification

o Provide MEP design input into the PHPP assessment

o Develop a spatially coordinated MEP design

o Building Regulations Part L Compliance Assessments

o Building Regulations Part O Limiting Overheating Analysis

o Ongoing site inspections & reporting during the construction period

o 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.

PROJECT OVERVIEW

Hannan Associates are providing Building Services Engineering consultancy for the major refurbishment & reconfiguration of Ronald McDonald House Alder Hey at the Alder Hey Children’s Hospital.

Ronald McDonald House UK provide free ‘home away from home’ accommodation for families whose children are undergoing treatment, giving them a warm and welcoming environment where they can stay for as long as they need.

The brief focused on optimising flexibility, enhancing public-facing facilities, and future-proofing the building’s capacity to support evolving healthcare models. The team undertook an in-depth review of existing spaces, operational needs, and feedback from families and staff across the Charity’s UK network. Critically, the proposals also needed to allow for a phased redevelopment which would allow half the building to remain operational during construction – preserving vital support for families.

Central to the scheme is the relocation of the main entrance from the east to the west of the site to improve integration with green spaces and community areas and provide a more visible and welcoming arrival point. 

Accommodation has been carefully rebalanced to prioritise accessibility and family flexibility. While the total number of bedrooms is reduced from 68 to 62, the scheme introduces larger, more accessible units, upgraded ensuites, and additional flexible family rooms. New family kitchens on each floor and fully refurbished bedrooms offer improved living conditions tailored to the unique challenges faced by residents.

Communal and day-visitor spaces will be significantly upgraded, with new facilities for family support, relaxation, and wellbeing. These include spaces for hairdressing, yoga, quiet reflection and outdoor play. A new landscaped garden further enhances the experience for residents and visitors alike – supporting mental and physical wellbeing through contact with nature.

While designing the MEP systems we have remained mindful of the charity’s mission and operational requirements to ensure that the work is undertaken as sensitively as possible while delivering meaningful, user-focused enhancements that support long-term care.
