Hassacarr Close
Building a sustainable business means we consider the impact we have on the environment and in our communities.
The self-funded development of our Head Office at Hassacarr Close, is a testament to our sustainable ethos, with the following environmental initiatives included:
- Biomass boiler using waste wood from our joinery workshop (previously destined for landfill)
- Photovoltaic layer to run our air conditioning systems
- Shading for windows (brise soleil)
- Grey water for toilets pumped from on-site, underground rainwater storage tanks
- Solar panels for heating domestic hot water
- Re-use of salvaged material & finishes
- Sustainable underground drainage systems
Work involved the major extension and alteration of three existing business units,stripping the existing buildings back to their steel frames and transforming them into a mix of B1 business units and B8 industrial units. Simpson occupies the largest of the three. Five B1 business units are also now housed in the fourth, new building.
More recently, we have acquired an existing industrial unit immediately adjacent to our joinery manufacturing facility and business park. We have undertaken the structural modification this unit now know as ‘Compass House’ to form 4 sub units. Works included stripping existing cladding, followed by the installation of new high-performing cladding and sheeting rails, new PV and a mansafe system, thermally insulated sectional shutter doors, an external sustainable paving system, and a treatment plant for the foul drainage system and EV charging facilities.
By utilising high performance materials, the EPC rating is A11-A12.
Recommended Projects

Salford Cathedral
Back in 2022, Simpson was appointed as the main contractor to deliver the conservation and reordering works at Salford Cathedral, a landmark project that has carefully restored and enhanced this important building.
Externally, the programme comprised the complete removal andreplacement of the cathedral’s roof, extensive masonry conservation repairs,and specialist restoration works to the spire, undertaken with the assistanceof a steeplejack. The stonework was carefully cleaned using Thermotechtechnology and fully repointed, while the historic stained-glass windows wereexpertly restored.
Internally, the project included the installation of a newfloor incorporating underfloor heating, together with the demolition of theexisting toilet and confessional block and the construction of new toiletfacilities and confessional rooms. A new mechanical, electrical and lightingsystem was also introduced. High-quality finishes and decorative works werecompleted throughout, including specialist ceiling painting with intricatestencilling, fine joinery, detailed metalwork and the introduction of a strikingnew altar and font.
The cathedral finally reopened its doors in July and hasbeen well received by the Diocese and the wider community. We are immenselyproud to have contributed to the preservation and revitalisation of such asignificant heritage asset, helping safeguard its legacy for futuregenerations.
Bradford Arts Centre
Formally known as ‘Kala Sangam’, Simpson completed the redevelopment of the newly named ‘Bradford Arts Centre’.
The 75 week program has seen an extensive reconfiguration and upgrade to the existing building facilities creating a state-of-the-art, space for artists, audiences and businesses, reconnecting the building and arts centre to the local community.
The project has seen the creation of a new theatre, five dance studios, a new central staircase and a permanent home for volunteer-led community radio station Bradford Community Broadcasting (BCB).
The introduction of a new entrance, two new lifts and a dedicated changing place facility now ensures the building is fully accessible for the first time in its 140-year history.
Endsleigh Convent
Built in the late 1800s, Endsleigh Convent in Filey served as a convent and holiday retreat for the Sisters of Mercy of the Middlesbrough Diocese.
The goal was to sensitively redevelop the historic structure into five high-end residential apartments, preserving its architectural character while introducing modern functionality and comfort. The project aimed to honour the building’s heritage while adapting it for contemporary coastal living.
The development has seen
- Internal remodelling carried out across all floors to create 5 spacious, open-plan apartments.
- Extensive structural works to support the new layouts and to accommodate a platform lift serving all levels.
- The former chapel underwent a thoughtful extension, transforming it into a unique residence with “upside-down” living:
The redevelopment of Endsleigh Convent successfully blends heritage preservation with modern design, creating a collection of distinctive homes that respect the building’s past while embracing its future. The project stands as a model for adaptive reuse in a sensitive coastal setting.
