A chapel hall, fixed without hired access equipment
Community & Worship · design target set by the brief, not a regulation
Illustrative worked example. This is a realistic brief run through Echo using the same method a real report uses — not an account of a named past client. See every case study for more, including which of these are real, permissioned projects as they're added.
The brief
The volunteer trustees of a Methodist chapel hall — home to a weekly toddler group, a Saturday food bank, and Sunday service — had reached the point where toddler-group leaders and food-bank volunteers couldn't hear each other across the room, and the Sunday reading was regularly lost by the back pews.
Chapel hall, single storey
16 × 10 × 6.5 m, about 1,040 m³ — brick walls, parquet floor, plaster ceiling with exposed roof trusses.
Brick, parquet and a high plaster ceiling put the hall at roughly 1.3 seconds — characterful for a service, but the direct cause of the toddler-group and food-bank complaints during the room's busier weekday use.
The standard, and the target
There's no statutory reverberation limit for a community hall, so the brief was set by what the room needed to do day to day: readable speech at the back for a service, and normal conversation across a room full of prams and folding tables the rest of the week — in practice, something in the 0.8 to 0.9 second range.
The constraint
The trustees were explicit up front: no budget for a contractor lift or scaffolding, and the exposed roof trusses — original to the building and a feature everyone liked — were not to be boxed in under any circumstances. Anything proposed had to be fittable by the volunteer team themselves from a stepladder.
The decision
Everything landed within reach of a stepladder: heavy curtains on a simple track at the two tall side windows, a carpet runner down the central aisle only (kept the rest of the floor clear for the food bank's folding tables), and upholstered seat pads on the stacking chairs replacing bare plastic.
Every route considered, vendor-neutral — we don't sell any of it.
- Curtains at the side windowsabout 18 m²
Fitted by the trustees themselves on a simple track — no lift or scaffold needed.
- Carpet runner, central aisle onlyabout 24 m²
Kept the rest of the floor clear and flexible for the food bank's tables.
- Upholstered seat pads on stacking chairs60 chairs
Small individually, but 60 of them add up — and nobody had to touch a wall or the trusses.
The outcome
The three changes brought the hall from roughly 1.3 seconds to around 0.85 — inside the range the brief called for, fitted entirely by volunteers, and without a single fixing anywhere near the trusses.
Indicative figures for this example, from the same method a real report uses. Not a measured survey and not a compliance certificate — where one is required, that's a survey to BS EN ISO 3382-2.

Why not fix panels to the brick walls?
It would likely have worked well, but it needed drilling into original masonry and reaching well above stepladder height in places — outside what the trustees' own volunteer team could safely fit themselves, which was the constraint that shaped the whole brief.
Is this a survey or a certificate for the hall's committee minutes?
No — it's an indicative design-stage prediction using the same method the report uses, not a measured survey. It's useful for deciding what to buy, not for a formal compliance record.
Would this suit a hall that does host scaffolding-scale work anyway?
If a lift or scaffold is already on site for another reason, ceiling-level treatment usually gets further for less material — this example is specifically about the routes that work when that access isn't available at all.
