Reading’s commercial towers, managed

Reading from above is a Thames Valley town that grew up rather than out. The town centre clusters around the station, and the taller buildings that define its skyline are, for the most part, commercial: office towers built through the technology and finance boom, business-park blocks at the edges, and a growing band of mixed-use schemes where residential floors sit above offices and retail. That commercial weighting gives Reading's tall stock a management profile that is different from a city dominated by residential towers, and the differences are worth drawing out for anyone running buildings there.

A skyline built on offices

The defining feature of Reading's taller buildings is that many of them are workplaces rather than homes. That changes the regulatory centre of gravity. The occupation-phase higher-risk building regime under the Building Safety Act 2022 is built around residential buildings: a higher-risk building is at least 18 metres or at least seven storeys with at least two residential units (gov.uk). A pure office tower, however tall, does not meet that definition.

That does not mean an office tower is lightly regulated. The fire risk assessment duty under the Regulatory Reform (Fire Safety) Order 2005 applies to it as a workplace, and the responsible person carries real obligations for the safety of the people who work there. But the specific higher-risk building machinery, registration, the Accountable Person, the safety case, attaches to residential buildings, and a manager who treats every tall building the same way will either over-apply duties that do not bite or, worse, miss the point at which a building does fall in scope.

Where mixed use changes the answer

The interesting buildings in Reading are the mixed-use ones, because they are where the residential thresholds start to matter. A scheme with offices on the lower floors and flats above is a single building that may well cross the higher-risk threshold once you count its height and its residential units. The presence of even two residential units in a tall enough building changes what the law asks.

This is the trap on a commercially-minded skyline. A management team used to running offices may not have the residential-safety reflexes that a higher-risk building demands, and a mixed-use block can slide into scope without anyone consciously deciding it has. The honest first task on any tall mixed-use building is to establish plainly whether it meets the threshold, and to manage it accordingly if it does. Our note on building safety beyond the higher-risk threshold covers the buildings that sit just under the line and still carry serious duties.

The shared-occupancy challenge

Commercial and mixed-use towers share a problem that pure residential blocks have in milder form: many tenants, many fit-outs, and constant change. An office floor is re-partitioned, a tenant installs a comms room, a café opens at ground level. Each change can affect compartmentation, escape routes and fire loading, and each is often carried out by a tenant's contractor rather than the building's own team.

For the manager, this means the building's safety picture is being altered by people they do not employ, on a schedule they do not set. The practical responses are unglamorous:

• A permit regime so that work affecting fire safety or structure is known about before it happens, not discovered afterwards.
• An up-to-date plan set, so that a re-partitioned floor is reflected in the record rather than diverging from it.
• A clear line on who is responsible for reinstating compartmentation after a tenant's works, written down rather than assumed.

Buildings that handle multi-tenant change well are the ones where the record keeps pace with the building. Buildings that handle it badly are the ones where the plans show a layout that stopped being true three fit-outs ago.

Lifts, plant and the things that must keep running

Commercial towers are lift-dependent in a way that lower buildings are not, and the maintenance obligations follow. Passenger-carrying lifting equipment requires a thorough examination every six months under LOLER, and load-only equipment every 12 months or in line with a written scheme (HSE). In a busy office tower, lift availability is also a business issue, which tends to keep maintenance honest, but the statutory examination is a separate discipline from keeping the lifts running, and the two should not be confused.

The same goes for the plant a commercial building leans on heavily: chillers, generators, building management systems. These are assets with their own service intervals, and on a multi-tenant building the question of who pays and who arranges can blur the question of who is responsible for doing it at all.

One record across many tenancies

The recurring theme on a commercial skyline is multiplicity: many tenants, many contractors, many simultaneous changes. The buildings that stay legible are the ones where all of that resolves to a single, current record of the building rather than a set of files that each tenant's managing agent keeps separately.

A single source of truth that holds the plans, the asset register, the compliance calendar and the change history against the building, not against any one tenancy, is what lets a manager answer questions across a busy, shifting tower. SAMRISK is built for that kind of multi-reader building, where the fire risk assessment, the lift examinations and the latest fit-out all have to be seen together. Reading's commercial towers are not harder to manage than residential ones; they are differently demanding, and the demand is mostly about keeping one accurate picture across a building that never quite holds still.
