The brief, the constraint, the fix.
Each of these is an illustrative worked example — a realistic brief run through Echo using the same method a real report uses — not an account of a named past client. Real, permissioned projects will join these as they come in.
A Victorian classroom, brought inside BB93
A worked example: a Victorian primary classroom well over BB93's 0.8-second refurbishment limit, treated without touching the cornicing. Standard, method, and every route, vendor-neutral.

WELL v2 — Reverberation Time featureRead it →A period lobby and bar, without touching the fabric
A worked example: an independent hotel's stone-and-marble lobby and bar, reflective enough that review sites had started to notice, fixed within listed-building constraints.
No statutory target — guest-experience briefRead it →A chapel hall, fixed without hired access equipment

No statutory target — customer-experience briefRead it →A co-working floor, fixed within a dilapidations clause
A worked example: a co-working operator's exposed-brick floor, too reverberant for its members' calls, fixed entirely with removable furniture because the head lease required a bare-shell return.
No statutory target — member-experience briefRead it →A meeting house built for silence, hired out for speech
A worked example: a Quaker meeting house where the unprogrammed worship needs almost nothing acoustically, but the weekday community-hire income depends on speech actually working. Standard, method, and every route, vendor-neutral.
No statutory target — dual-use briefRead it →A seminar room nobody wanted to book
A worked example: a university seminar room with a glass wall and a hard floor, quietly avoided by staff running discussion-based teaching. Standard, method, and every route, vendor-neutral.

A worked example: a boutique spin studio in a converted warehouse unit, where instructor cueing was getting lost under the room's own sound system. Standard, method, and every route, vendor-neutral.
No single mandated figure — Sport England guidance used as referenceRead it →A dental reception, quietened for two different reasons at once
A worked example: a private dental practice reception where card-payment conversations and treatment-plan discussions carried the length of a small waiting room. Standard, method, and every route, vendor-neutral.
HTM 08-01 — Acoustics (used as best-practice reference for a private practice)Read it →A bookshop that wanted quiet, and got it back
A worked example: an independent bookshop in a converted Georgian townhouse, where hard floors and high ceilings meant till-point conversations carried across the whole ground floor. Standard, method, and every route, vendor-neutral.
No statutory target — browsing-and-privacy briefRead it →A call-centre floor, fixed for distraction rather than volume
A worked example: a 40-desk customer-service floor where agents were being distracted by the desk next to them rather than helped by ambient masking. Standard, method, and every route, vendor-neutral.
