Why a Railway Arch?
Arches provide the ceiling height for commercial roasters and extraction systems, the robust floor loading for heavy equipment, and the industrial character that specialty coffee customers expect. The option to combine production and retail in one space (roastery + cafe) is a natural fit for the arch layout, with production at the rear and the cafe at the front.
Advantages
- +Industrial aesthetic that aligns with specialty coffee branding
- +Combine roasting and retail in one unit
- +Temperature stability from thick masonry walls
- +Lower rents than high-street retail for equivalent space
- +RHL rates multiplier reduces business rates
- +Clustering with other food and drink businesses drives footfall
Challenges
- -Commercial roaster is a major capital expense (~£60,000)
- -Extraction and ventilation systems are complex and costly in arches
- -Listed viaducts may restrict external flue installation
- -90–180 day green bean inventory buffer needed before revenue stabilises
- -Single-aspect arches create ventilation engineering challenges
Cost Profile
| Cost Element | Low Estimate | High Estimate |
|---|---|---|
| Fit-Out (per sqft) | £65 | £150 |
| Fit-Out (600 sqft) | £39,000 | £90,000 |
| Typical Rateable Value | £12,000 | £30,000 |
| England annual base rates before reliefs | £4,584 | £11,460 |
Rates use England’s 2026/27 base multipliers. Supplements, transitional relief and other reliefs are excluded. Scotland and Wales use different rules.
This example assumes qualifying RHL use. Confirm the property’s actual use with the council; sector labels alone do not establish eligibility.

Would an arch work for your business?
Build a short list of checks to take to a viewing. This helps you investigate suitability; it does not confirm planning permission or landlord approval.
