Installed Under Manchester's Victorian Railway Arches
When a Manchester-based homeless charity needed a professional, purpose-built workspace, a standard office fit-out wasn't an option. The space available was beneath a set of Victorian railway arches — dramatic, characterful, and entirely unconventional. What Embassy needed was a building that could meet the rigorous demands of commercial use, look the part in an extraordinary setting, and be delivered on time without disrupting the vital work the charity carries out every day. A commercial log cabin from Timber Building Specialists turned out to be exactly the right answer.
This is the story of how we designed, specified, and installed a bespoke 6m x 5m commercial log cabin in Manchester — and how it now serves as the operational heart of a charity doing genuinely important work across Greater Manchester.
Why Embassy Needed a Bespoke Commercial Workspace
Embassy is a charity that provides practical support to people experiencing homelessness in Manchester. Their work is hands-on, human, and highly organised — and like any serious organisation, they need proper workspace to run effectively. Administration, case management, team meetings, and liaison with partner agencies all require a professional environment: somewhere staff can focus, where confidential conversations can take place, and where the charity can credibly receive visitors and stakeholders.
The challenge was finding a solution that worked within the architectural constraints of their site — a series of Victorian railway arches in Manchester that provide the charity with affordable, centrally located premises. The arches themselves are extraordinary: tall, graffiti-covered brickwork, full of character and history. But fitting a conventional building inside that footprint, with all the commercial requirements that entails, was no straightforward task.
Embassy didn't need a garden shed. They needed a genuinely commercial timber building: properly insulated, fire-rated to commercial standards, electrically fitted out, and finished to a professional standard that would reflect well on the organisation and those it serves. After exploring their options, they came to Timber Building Specialists.
The Brief: A Professional Office Under the Arches
The brief was clear from the outset. Embassy needed a standalone building that could function as a proper office and provide dedicated meeting room space — all within the footprint available beneath the railway arches. The structure had to meet commercial building requirements, which introduced a layer of complexity that goes well beyond a standard residential installation.
Specifically, the building needed:
-
Robust structural performance — a 6m x 5m footprint using heavy-section wall logs capable of handling the demands of a commercial environment
-
Full thermal insulation — staff working in the cabin year-round needed it to be properly heated and comfortable in all seasons
-
Fire protection — for commercial use, the cabin would require a 30-minute fire protection treatment throughout, a requirement that influences both the specification and the installation programme
-
Professional finish — the aesthetic had to be appropriate for a working charity office, not a garden room
-
Electrical fit-out — fully wired for computers, lighting, heating, and communications
-
A durable, low-maintenance exterior — given the exposed nature of the site
Why a log cabin rather than a modular office unit or a prefabricated steel building? Several reasons. The thermal mass of solid timber logs provides natural temperature regulation. The structural integrity of interlocking log construction is well proven. And the aesthetic — particularly when finished in neutral tones — can look genuinely striking rather than utilitarian. For Embassy's setting under the Victorian arches, a well-specified timber building would complement the existing character of the site rather than clash with it.
They chose Timber Building Specialists because of our track record with commercial and bespoke projects, our end-to-end design-to-installation service, and our ability to handle the specific technical requirements that commercial use demands.
Design & Specification: Built for Commercial Use
This wasn't an off-the-shelf cabin. Every element of the specification was chosen to meet the demands of a permanent commercial workspace in Greater Manchester — and to ensure the building would perform reliably for many years to come.
Structure and Wall Logs
The walls are constructed from 95mm x 185mm interlocking wall logs — heavy, solid timber that provides genuine structural rigidity and a high level of inherent thermal and acoustic performance. These are not the lightweight logs you'll find in entry-level garden cabins. At this section size, the wall logs provide a substantial base for insulation, create a quiet interior environment suitable for meetings and focused work, and give the building a solid, permanent feel.
Glazing
22mm double glazing is fitted throughout, across all window and door openings. The glazing units deliver strong thermal performance, reducing heat loss in winter and preventing excessive solar gain in summer — important in a building that will be occupied by staff throughout the year. The generous glazing panels visible on the front elevation and side face bring in substantial natural light, making the interior feel open and professional rather than bunker-like.
Flooring
The floor is constructed from 28mm boarding on an insulated timber framed base. The combination of a substantial floor deck and a fully insulated void beneath means the floor stays warm underfoot, even in winter — a detail that matters considerably in a building where staff will spend full working days.
Roof
The roof is finished with EPDM rubber roofing — a premium flat-roof membrane specified for its longevity, weather resistance, and near-zero maintenance requirements. EPDM performs well in the UK climate, handling freeze-thaw cycles and prolonged wet weather without degrading. Full guttering is fitted, managing rainwater drainage away from the building and the surrounding area.
The roof structure itself is insulated, completing the thermal envelope of the building and ensuring that heating costs are kept manageable year-round.
Fire Protection
For commercial use, the cabin was treated with a 30-minute fire protection system throughout. This is a requirement that distinguishes commercial log cabin builds from domestic ones, and it's an area where Timber Building Specialists has direct experience. The treatment is applied to the timber structure and forms part of the compliance package for commercial occupancy. All relevant documentation accompanies the installation.
Doors and Paintwork
The double entrance door — flanked by generous side glazing panels — is pre-painted in anthracite grey. The anthracite finish gives the entrance a clean, modern, commercial character and contrasts well against the hand-painted light grey walls. The full front elevation, with its wide central door, side panels, and large fixed windows on each side, reads as genuinely professional. There's nothing domestic about this building's appearance.
The walls were hand-painted in light grey — a calm, neutral tone that sits naturally against the Victorian brickwork of the arches without either disappearing into it or fighting against it.
Electrical Fit-Out
A full electrical fit-out was completed as part of the installation programme: lighting, power circuits, and connections for heating and communications. The building is ready to work from day one, without the need for Embassy to coordinate a separate electrician or manage any post-installation fit-out.

The Installation: Five Days Under the Arches
Installing a commercial log cabin beneath a set of Victorian railway arches in Manchester is not a standard installation brief. The setting introduced a set of logistical considerations that required careful planning before a single log was put in place.
Site Preparation
The timber framed base was constructed first, levelled precisely within the arch footprint. Working beneath the arches meant operating in a sheltered but spatially constrained environment — the arch geometry defined the available headroom and working radius at each stage of the build. Our installation team assessed the site in advance and planned the sequence of work to make the most efficient use of the space.
The shelter provided by the arches was, in many respects, an advantage. Manchester weather being what it is, having overhead cover during the build meant the installation could proceed without weather-related delays to the structural work.
The Build Programme
The full installation — from base preparation through to completed electrical fit-out — was completed in five days. That timeline reflects both the efficiency of log cabin construction as a building method and the preparation our team put in before arriving on site. Log cabin assembly, when the components are correctly prepared and the site is ready, is a fast and predictable process. For a charity like Embassy, minimising disruption to their operations was important, and a five-day programme achieved that.
Structural Assembly
The 95mm x 185mm wall logs were assembled using the interlocking corner system, building up the walls course by course. The heavy section of the logs means each course adds meaningful mass to the structure, and the interlocking joints provide both strength and weather resistance without reliance on additional fixings at every joint.
The roof structure was installed over the log walls, insulated, and then finished with the EPDM membrane and guttering. Windows and the pre-hung anthracite door set were fitted into the openings, and the 22mm double-glazed units were installed.
Fire Treatment and Finishing
The 30-minute fire protection treatment was applied to the structure as part of the installation programme. This is not a cosmetic treatment — it penetrates the timber and provides the required level of fire resistance for commercial occupancy. Following the fire treatment, the exterior walls were hand-painted in light grey, and the interior was prepared for the electrical fit-out.
Electrical Completion
The full electrical installation — lighting circuits, power points, and heating connections — was completed as the final stage of the five-day programme. By the time our team left the site, Embassy had a fully finished, fully compliant, electrically live commercial building ready for immediate occupation.
The Result: A Professional Home for Embassy's Work
Stand in front of the finished cabin and the setting is genuinely striking. The light grey walls and anthracite door and window frames read as clean and modern — a deliberate contrast to the aged, graffiti-covered Victorian brickwork of the arches behind. The generous glazing on the front elevation — the wide double door with its flanking side panels, the large fixed windows on either side — gives the building an open, welcoming presence. This is not a building that looks out of place. It looks considered, purposeful, and right.
From the side elevation, the rear fixed window continues the glazing theme, bringing light into what would otherwise be a dark internal corner. The EPDM flat roof sits flush and clean against the arch above, and the guttering carries rainwater away efficiently.
Inside, Embassy now has a proper office and dedicated meeting room space: warm, well-lit, acoustically comfortable, and fully equipped. Staff can work throughout the year without compromise. Meetings with stakeholders, partner agencies, and the people the charity supports can take place in a professional, dignified environment. The building reflects the seriousness and credibility of the work Embassy does.
For a charity operating in Manchester's city centre, where space is at a premium and budgets are always under pressure, the commercial log cabin has delivered something genuinely valuable: a bespoke, permanent, fully compliant workspace that cost a fraction of what a conventional build would have required, and that was ready for occupation in under a week from the start of installation.
Could a Commercial Log Cabin Work for Your Organisation?
Embassy's project is a compelling demonstration of what a properly specified commercial log cabin can achieve — but the same approach works across a wide range of organisations and applications. Charities, small businesses, professional practices, schools, and community organisations across Greater Manchester and the rest of the UK have used commercial timber buildings from Timber Building Specialists to create offices, meeting rooms, studios, and multi-use spaces that work hard and look excellent.
The key difference between a commercial log cabin and a domestic garden cabin lies in the specification. Commercial buildings require heavier wall logs, robust insulation packages, appropriate fire treatment, proper electrical installation, and durable exterior finishes. They also benefit from the kind of project management that keeps installations on programme and minimises disruption to the organisations they serve. These are exactly the details we focus on at Timber Building Specialists.
We offer a full design-to-installation service across the UK, with no need for our clients to manage multiple contractors or coordinate separate trades. From the initial design consultation through to the final electrical connection, our team handles every stage. Our experience across both domestic and commercial projects means we understand the requirements that apply to permanent commercial buildings — including fire treatment, insulation standards, and the documentation that organisations need for compliance purposes.
If your organisation is working with an unusual site, an unconventional footprint, or a specific commercial requirement — whether that's fire treatment, bespoke dimensions, or a particular finish — we'd welcome the opportunity to discuss what's possible. The Embassy installation under Manchester's railway arches is a good example of what can be achieved when a brief is taken seriously and a building is designed and built to genuinely meet it.
