Bringing Our Buildings Back to Life
Why Reusing Existing Buildings Can Create Lasting Community Value
Across London, many modest public buildings sit underused despite occupying valuable locations within parks, neighbourhoods and established communities. Harrow Council’s Bringing Our Buildings Back to Life programme is an important local response to that challenge, inviting new occupiers and operators to consider how existing buildings can support viable businesses, services and community uses rather than remaining vacant.
Folly Architects joined the programme’s Steering Group to contribute architectural insight to the process. Our role reflects the same principles that inform our wider Architectural Design work: understand the building first, test what is realistically possible and develop interventions that are proportionate to the opportunity. For projects involving older or sensitive buildings, this also needs to be considered alongside Planning Consultancy and the wider planning context.
Adaptive reuse is not simply about finding a tenant for an empty building. It requires a practical understanding of condition, access, servicing, energy performance, fire safety, planning constraints, cost and long-term maintenance. Early coordination with Building Regulations requirements and proportionate Sustainability Advice can help turn a promising idea into a building that is safe, usable and financially sustainable.
Seeing Existing Buildings as Assets, Not Problems
Vacant and underused buildings are often judged primarily by their defects. A former pavilion, community room, changing facility or ancillary building may have dated services, poor thermal performance, awkward access or years of deferred maintenance. Those issues matter, but they do not necessarily define the building’s future.
The starting point should be to understand what already exists and what value is embedded within it. Location, structure, character, local familiarity and the relationship with surrounding open space can all be difficult or expensive to reproduce through new construction. Reuse allows those qualities to become part of the brief rather than being discarded.
This is particularly relevant in an established borough such as Harrow, where small buildings can have a strong relationship with local parks and neighbourhoods. A modest intervention may be capable of creating a café, studio, health or wellbeing space, community facility or specialist local service, provided that the proposed use is appropriate to the building and commercially realistic.
Adaptive Reuse Needs More Than a Good Idea
The strongest reuse proposals are usually those that align three things: the needs of the future occupier, the physical capability of the building and the statutory approval route. If one of these is ignored, an attractive concept can quickly become difficult to deliver.
Before committing to a lease, fit-out or business model, an applicant should understand the building’s condition, likely repair liabilities, existing utilities, drainage, accessibility and any constraints on alteration. The proposed use may also introduce new requirements for ventilation, sanitary provision, fire precautions, escape, acoustic separation or servicing. These are not reasons to avoid reuse; they are reasons to test feasibility properly before investment decisions are fixed.
The design process is therefore as much about risk reduction as creativity. Our guidance on the architectural design process explains why early briefing, option testing and technical coordination are valuable before a scheme moves into detailed design or construction.
Planning, Heritage and Building Regulations
A change in activity does not automatically mean that a building can be occupied without further approvals. Depending on the existing and proposed use, works may require planning permission, Building Regulations approval, landlord consent or other statutory input. External alterations, signage, new openings, ventilation equipment, extraction routes, ramps and changes to landscape or access can all affect the approval strategy.
Where a building sits within a conservation area or has particular local character, design decisions may require greater sensitivity. Materials, proportions, roof form, windows, doors and the relationship with the surrounding open space can all influence what is appropriate. Our article on building in a Conservation Area explores why context should inform design rather than being treated as an obstacle at the end of the process.
Building Regulations should also be considered early. A reuse project may involve upgrades to fire safety, structure, thermal performance, ventilation, drainage and accessibility. The existing building will rarely behave like a blank-sheet new build, so the design needs to work intelligently with existing fabric while demonstrating compliance for the proposed works and use.
Frequently asked questions
The following questions and answers summarise common queries relating to this topic.
Adaptive reuse is the process of giving an existing building a new or revised purpose while retaining as much useful fabric and character as is reasonably possible. It can range from modest refurbishment to substantial alterations, depending on the building and proposed use.
Review the condition of the building, lease responsibilities, access, services, drainage, fire safety, accessibility, planning constraints, likely Building Regulations work and the cost of repairs and fit-out. These issues should be tested against the proposed business or community use before major commitments are made.
Yes. A careful design strategy can improve safety, comfort, energy performance and usability while retaining important architectural features. The appropriate balance depends on the significance, condition and construction of the individual building.
Early architectural advice can identify constraints before a lease, budget or design is fixed. It helps coordinate the proposed use with planning, Building Regulations, building condition, layout, servicing and buildability so that the project has a clearer route from idea to occupation.
Sustainability Through Retention and Careful Intervention
One of the strongest arguments for adaptive reuse is that it starts with what is already there. Retaining a viable building avoids unnecessary demolition and reduces the demand for new construction materials, while also preserving the social and spatial value already associated with the site.
That does not mean every existing element should automatically be retained. Poor-performing components may need repair or replacement, and some buildings will require substantial investment before they can support a new use. The objective is to make informed decisions: retain where retention has value, upgrade where performance can be improved and intervene where change is necessary for safety, accessibility or long-term use.
A practical sustainability strategy can include fabric improvements, efficient services, better daylight, natural ventilation where appropriate, durable materials and careful maintenance planning. The most successful approach is normally one that balances operational performance with cost, heritage, buildability and the realistic lifespan of the proposed use.
Designing for Economic and Social Value
For community reuse to succeed, architecture cannot be separated from the business model. A beautifully designed space that is expensive to operate, difficult to maintain or inflexible in use may struggle over time. Equally, a commercially efficient proposal that ignores place, accessibility or community benefit may fail to make the most of the opportunity.
Good design can support both. Clear entrances, welcoming thresholds, flexible internal layouts, sensible servicing and strong connections to surrounding landscape can improve user experience while also helping an operator run the building efficiently. Small decisions about storage, deliveries, refuse, security, lighting and maintenance often have a significant effect on whether a space works day to day.
This is where multidisciplinary thinking matters. The architectural proposal, planning strategy, technical requirements and operational needs should be tested together. The objective is not to over-design a modest building, but to make the right interventions in the right places.
A Replicable Approach to Underused Buildings
Harrow Council’s programme demonstrates a useful principle for local authorities, landowners and community organisations: underused buildings do not need to remain liabilities simply because their original function has disappeared. With clear information, realistic expectations and access to professional advice, they can be repositioned as useful local assets.
For prospective occupiers, the key is to investigate before committing. Understand the condition of the building, identify approval requirements, test the proposed use against the available space and establish a realistic allowance for repair, fit-out and ongoing operation. Early architectural input can help separate viable opportunities from ideas that may become disproportionately expensive or difficult to approve.
For Folly Architects, involvement in Bringing Our Buildings Back to Life sits naturally alongside our wider work in refurbishment, planning, technical design and reuse. The most sustainable building is not automatically the oldest or the newest; it is the one that can be made safe, useful, adaptable and valued for the long term.
