Toilets, Storage & Back-of-House

Few things degrade the daily experience of an office faster than poor washrooms - too few of them, badly located, poorly ventilated, hard to keep clean, or undignified to use. They are visited by everyone, many times a day, and their quality is read, fairly or not, as a measure of how much the organisation respects its people. A mean, grudging, permanently-queued washroom sours a building no amount of lobby marble can sweeten; a clean, well-ventilated, well-lit, adequately-sized one is a quiet daily reassurance. So although no one photographs them, washrooms deserve real design attention, not the leftover corner.

The single most important professional discipline here is knowing what to defer. The number of sanitary fixtures required - WCs, urinals, washbasins, for the building's occupancy and its gender split - is set by the National Building Code and the relevant standards, and it is not something to estimate or copy from another project. Get it wrong and you have either an illegal, under-provided building or a wastefully over-provided one, and the fix after construction is expensive. So the rule is firm: take the fixture counts from the current NBC and the plumbing consultant, for the actual occupancy, always. This lesson teaches you to plan good washrooms; it explicitly defers the binding numbers to the code and the specialist.

What design judgement *does* own is everything around the count. Location and distribution - washrooms reachable from everywhere people work without a long trek, sensibly distributed on large floors rather than all clustered at one end. Ventilation and drainage - proper extract so nothing lingers, resolved with the services engineer. Ease of cleaning and durability - surfaces and details that stay decent under heavy daily use, because a washroom that cannot be kept clean will not be. Dignity, privacy and inclusion - including accessible toilets whose dimensions come from the accessibility standards, and increasingly gender-neutral and culturally appropriate provision thought through for the specific organisation. And the small humane touches - good light, somewhere to set things down, a mirror, reliable supplies - that cost little and are noticed daily. Design all of that well and defer the counts to code, and the most-used rooms in the building quietly support the day instead of undermining it.

Storage is where the shift to hybrid and agile working rewrote the brief most completely, and a designer who plans it the old way will get it badly wrong. In the traditional assigned-desk office, personal storage was obvious: everyone had a desk with drawers and a pedestal, a place that was *theirs* to keep a coat, a bag, papers, a photo, a spare pair of shoes. When desks become shared - hot-desking, activity-based working, desk-sharing ratios below one-to-one (Module 7) - that personal anchor vanishes, and if nothing replaces it, people arrive each morning with nowhere to put their things and no sense of belonging. The result is bags on the floor, coats on chairs, and a low-grade daily friction that undermines the whole agile strategy.

The replacement is personal lockers, and they become a surprisingly important piece of the agile office rather than an afterthought. A good locker gives a person who no longer has a desk a small, secure, reliable home base: somewhere to leave a coat and bag, lock away a laptop or valuables, keep the few personal things that make the day workable. The design questions are real - enough lockers for the sharing ratio and pattern (daily-assigned, or booked, or permanent), sensibly located on the route between arrival and the work settings so they are convenient rather than a detour, the right size and security, and power inside for charging where useful. Get lockers right and agile working feels liberating; get them wrong or skimp on them and it feels like being dispossessed.

Beyond the personal, offices still need team and general storage even as paper declines - project materials, samples and physical work (especially in a design or making firm), shared equipment, stationery, supplies, seasonal and archive storage - and the agile office's clean, un-cluttered look depends entirely on there being enough well-planned storage to absorb all of it. The classic failure is designing a beautiful paperless-looking floor with nowhere to actually put the stuff that real work generates, so it ends up piled on surfaces and the whole scheme looks defeated within months. Plan generous, well-located storage - personal lockers, team stores, general supply - calibrated to how this specific organisation actually works and what it really keeps, treating any storage-per-person benchmark as illustrative. Storage is not glamorous, but in the agile office it is the quiet infrastructure that makes the glamour possible.

Behind the visible office is a set of service rooms that do essential work and, if badly placed or under-provided, cause daily irritation out of all proportion to their size. The print and copy room is the classic example. Printing has declined but not vanished, and printers are noisy, sometimes smelly, and draw people to them - so a printer dumped in the middle of a quiet work area is a perpetual disturbance, while a well-designed print and utility room (or well-placed print points) contains the noise, holds the supplies and paper, gives space for collating and the inevitable recycling, and sits where it is convenient without intruding on focus space. It is a small room that, done thoughtlessly, annoys people all day.

The server, comms and IT rooms are the building's nervous system and have hard technical requirements that are not negotiable and not yours alone to set. They need reliable power (often with backup), serious cooling because IT equipment generates significant heat, security of access, and proper cable management and routing back to the workspace - and the specifics of cooling, power and fire protection for these rooms must be resolved with the IT, electrical, mechanical and fire specialists, not improvised. What the designer owns is planning for them properly from the start: giving them adequate, sensibly-located space with the routes and risers they need, rather than squeezing critical infrastructure into a leftover cupboard that cannot be cooled or accessed. A server room that overheats because no one planned its cooling is a failure that takes the whole office down with it.

Then there is the quieter tier of service space that every functioning office needs and thoughtless ones forget: the cleaners' store and janitor's room with a sink and space for equipment (without which the building cannot actually be kept clean), electrical and services rooms and risers, pantry back-of-house for the cafe's stores and waste, general building services, and space for deliveries, loading and waste, including the real and growing demand for segregated waste and recycling. None of these is glamorous; all of them are the difference between a building that runs smoothly and one that is perpetually improvising. The professional habit is to programme them deliberately, with the services and facilities team, as part of the plan - not to discover at the end that there is nowhere for the cleaner's trolley, the recycling or the incoming deliveries.

Pulled together, all of this - washrooms, storage, print and utility, server and comms, cleaners' and services rooms, loading and waste - is the office's back-of-house, and the mark of an experienced workplace designer is taking it as seriously as the front-of-house. Back-of-house is a system, not a set of leftovers: the service circulation that lets cleaners, deliveries and maintenance move without crossing the polished front spaces; the risers and routes that carry power, data, water and air to where they are needed; the waste and recycling flow from every pantry and print point to the loading bay; the storage that keeps the visible office uncluttered. When this system is planned well, the front-of-house can be calm and beautiful because the machinery is handled elsewhere. When it is an afterthought, the machinery leaks into the visible office - trolleys in corridors, boxes in meeting rooms, bins where people eat - and the whole thing feels shabby however good the design intent.

There is a useful professional truth here: clients and visitors judge the front, but staff live in the whole. The people who actually work in a building experience its back-of-house every day - the queue for the toilet, the locker that is a long detour, the printer that disturbs them, the missing storage that clutters their floor - and those daily frictions shape how they feel about the workplace far more than the photographable moments. An office that invests only in the visible and neglects the essential is a common and expensive mistake, and the emptiness that follows is often blamed on 'hybrid' when the real cause is a daily experience that quietly grinds people down.

So the discipline this lesson leaves you with is simple and, for a designer, defining. Programme the unglamorous essentials deliberately and early, with the plumbing, services, IT and facilities specialists; size and place them for how the organisation really works; defer the binding numbers - sanitary fixtures, cooling, power, fire, accessible dimensions - to the code and the consultants; and never treat them as the space left over after the nice parts are done. Get the back-of-house right and nobody will ever praise it - which is exactly the point. It will simply let the office work, day after ordinary day, which is the most valuable thing an office can do.
