Planning History

Hope Street, a trauma-informed residential centre for justice-involved women, underwent a rigorous planning process. Located on The Avenue, Southampton, the site had an existing consent (17/02578-FUL) for residential development. A new application was submitted in 2020 by One Small Thing, aligning with conservation area policies and local housing needs. Pre-application discussions with Southampton City Council and the Design Advisory Panel refined the scheme, ensuring contextual sensitivity. Planning permission was granted in 2021 following revisions to massing, landscaping, and sustainability measures, including achieving BREEAM Excellent. The project sets a precedent for community-focused, rehabilitative housing.

The Design Process

Hope Street is a pioneering residential community in Southampton, designed by Snug Architects in collaboration with One Small Thing, a charity committed to reforming the justice system for women and their children. The project serves as an alternative to incarceration, offering a supportive environment for women who have experienced trauma.

The scheme consists of two primary structures: a front-facing 'Hub' building and a rear residential block. The 'Hub' includes a public café, consultation rooms, therapy suites, offices, and communal living spaces, fostering community engagement and skill development. The residential building houses eight shared flats, accommodating up to 24 women and their children, designed to feel like a home rather than an institution.

Trauma-informed principles underpin the design. Natural materials such as buff brick, green zinc, and vertical oak create a warm and welcoming atmosphere. Large windows and skylights enhance the connection to nature and promote well-being.

The therapeutic garden, positioned between the buildings, provides a sanctuary for reflection and communal activities. Featuring a central river birch tree symbolizing renewal, the garden incorporates biophilic design, offering a calming environment that fosters responsibility and personal growth.

Safety and dignity are integral. The layout balances natural surveillance, privacy and the creation of a sense of community. Shared spaces encourage interaction, while private areas provide retreat, supporting both community and autonomy.

Hope Street represents a shift in the U.K. justice system, demonstrating how thoughtful architecture can support rehabilitation, reintegration, and long-term positive change for individuals and society.

Key Features

Hope Street redefines justice-focused housing through trauma-informed design, creating a safe and supportive environment for women and children. The residential building consists of eight shared flats, accommodating up to 24 women and their children in a homely setting rather than an institutional one. Designed to encourage independent living, each flat includes private bedrooms alongside shared kitchen and living spaces, fostering community and peer support. The scheme prioritises dignity and autonomy, ensuring a balance between privacy and communal engagement. With sustainability at its core, Hope Street is on track to achieve BREEAM Outstanding, setting a new benchmark for justice-aligned housing in

Sustainability

Hope Street, designed by Snug Architects in collaboration with One Small Thing, is a model of sustainability, actively addressing carbon reduction in both its construction and operation. The project’s focus is on reducing embodied carbon and minimizing energy consumption over its lifetime. To meet the BREEAM Outstanding target, key strategies were implemented: Cross-Laminated Timber (CLT): The use of CLT throughout the building provides significant environmental benefits, including reduced embodied carbon. CLT’s thermal performance and air-tightness support energy efficiency, while its renewable, low-carbon nature offsets the carbon emissions typically associated with conventional building materials. The use of CLT also minimized material waste during construction and sped up the building process, further reducing the overall carbon footprint. Energy Efficiency: The residential building incorporates an Air Source Heat Pump (ASHP) system, combined with underfloor heating and a photovoltaic (PV) array on the roof. These features significantly reduce the building's operational carbon emissions by providing renewable energy and maintaining an energy-efficient indoor environment. Mechanical Ventilation with Heat Recovery (MVHR): To ensure optimal energy use, the MVHR system in the Hub building recovers heat from exhaust air and transfers it to incoming fresh air, reducing the energy demand for heating. Stack ventilation, provided by opening rooflights, further supports natural cooling in the Hub, reducing the need for mechanical cooling and energy-intensive systems. Sustainable Drainage Systems (SuDS): Green roofs and intensive landscaping gardens manage rainwater runoff and contribute to local biodiversity. The SUDS system below the garden supports natural water management, reducing the risk of flooding and enhancing the site's environmental performance. With these strategies, Hope Street achieves a low-carbon lifestyle for its residents, fostering energy-efficient living while addressing the urgent need for carbon reduction in both construction and operation.
