Workspace & open plan: designed for the working day

UK workplace guidance sets the legal floor, but comfort lives well above it. In contract planning practice, 6–10 square metres gross per workstation — circulation, support and acoustics included — is the realistic band; the lower end only works when phone booths and quiet zones carry the overflow. The more useful measure than the average is the layout: eight square metres with the main route running behind people's chairs performs worse than seven planned around the actual flows. Hybrid working changes the arithmetic again. If simultaneous attendance never exceeds two thirds of headcount, the desk count can fall and the released floor should be reinvested in what almost every British open plan lacks — huddle rooms, call booths, a standing-height table to talk at — rather than handed back to the landlord. It is the ratio of desks to support settings, not the bare square metres, that decides whether the floor works.

Yes — with three layers doing different jobs. Absorb sound where it is made, with screens between desks and panels behind teams; interrupt the long sight-and-sound lines with storage and planting; and give the noisy activities somewhere else to happen, which is what booths and huddle spaces are for. A treated ceiling alone tames the echo but not the colleague two metres away — that is why ceilings disappoint when they are the whole strategy. The practical rule is to put absorbent material near the mouth rather than far from it: one panel behind a team table outperforms three square metres of acoustic ceiling above the quiet desks. Ask manufacturers for measured absorption values rather than adjectives, and check that the main circulation route does not run between two rows of desks — footfall on a hard floor is the noise source nobody budgets for and everyone hears at three in the afternoon.

The honest answer comes from your own occupancy, not from a benchmark: count desks in use at the busiest hour of a normal fortnight and add a margin for the full-house days. Most UK hybrid offices land somewhere between six and eight desks for every ten people, but the number matters less than the relief valves around it — bookable focus rooms, touch-down points and lockers that make sharing feel civilised rather than imposed. Two further conditions decide whether the ratio holds. Every desk must carry the same kit — monitor, dock, power — so that nobody arrives early to claim the good one, and teams need neighbourhoods with their own lockers and a small meeting setting, so that coming in means sitting with colleagues rather than beside a stranger. The booking system should help people sit together, not complicate the arrival. Get those right and a ratio of seven in ten feels generous; get them wrong and ten in ten still feels like a hotel.

Not the coffee machine — the working conditions. A chair better than the one at home, a screen at the right height, light that doesn't fight the monitor, and colleagues within reach but not within earshot. The office wins when it offers what home cannot: variety of settings. Desk for the routine, quiet room for the deep work, lounge for the conversation — one floor, several ways to work well. British staff are candid about the alternative: a spare-room desk and a laptop on a stack of books, which is why a properly adjustable task chair and a sit-stand desk are the two items on which no open plan budget should economise. The other thing home cannot supply is the accidental conversation — the colleague met at the tea point, the question answered across a bench — and that argues for neighbourhoods and a break area on the natural route rather than for more desks.

It needs to be planned for the full days and furnished for the quiet ones. On a Wednesday every attendee must have a desk without standing about; on a Friday the same floor must not look like a closed factory. The answer is neighbourhoods: small groups of desks with lockers and a huddle setting, occupied by a team on its office days, so that empty desks are scattered rather than concentrated at one end. Attendance patterns can also be steered — many British firms now assign anchor days by department so that the peak spreads across the week instead of collapsing onto two days. Plan the desk count on the busiest hour of a normal fortnight, plan the support settings on the whole week, and resist the temptation to size on the average: the average day does not exist, and the two days that do are the ones on which the office is judged.

The task chair and the height-adjustable desk are the two items on which economy costs more than it saves, because they are what the body uses for eight hours; a fully adjustable chair and a desk that allows part of the day standing address the musculoskeletal complaints that remain among the most common reasons for absence in British offices. Storage and pedestals can be simpler: robustness and mobility matter, finish quality does not. Acoustic screens should be chosen on measured values rather than looks. Support tables and standing-height tables can be plain as long as they are stable. The rule is to invest where the body touches the furniture for hours and to hold back where the furniture merely organises the space. A supplier worth working with will say so before being asked — and will put the samples in the room for a fortnight so that the people who will sit in the chairs can vote.
