The council expected a full soundproofing package. Measurement showed the building already did the job.

A terrace for eighty people, cleared on noise before the sound system had even been chosen.

Read the case studyA high-street parade of small shops with two storeys of flats aboveResidential

One question, one measurement: could a working shop be heard in the flats above it?

Read the case studyA three-storey brick building on a market-town high street, upper floors under conversionHospitality

Moving existing plant across a roof, cleared without spending anything on mitigation.

Read the case studyA modern hospital building with an external plant compound behind acoustic louvresHealthcare

The noise limit written before the equipment was ordered, not after it was installed.

Read the case studyA small rural housing development with an air source heat pump standing against a gable wallResidential

A heat pump on every plot, and a layout rule that let the design finish itself.

Read the case studyAn air source heat pump on a paved area close to a garden boundary, the neighbouring house beyondPlant noise

Read the case studyFloodlit outdoor padel courts with glass end walls and mesh fencing beside a car parkLeisure

Padel courts, North West

A sport with no agreed way of assessing it. We had to build the method first.

Read the case studyThe interior of a warehouse unit fitted out as a rehearsal and performance spaceLeisure

Music performance space, Yorkshire

A warehouse turned into a 100-seat venue, with the roof doing most of the work.

Read the case studyA large timber activity barn on a rural estate, surrounded by mature trees and open farmlandLeisure

Activity barn, West Midlands

A planning condition discharged without a single measurement, because measuring would have proved nothing.

Read the case studyTimber glamping pods and a hot tub on a hillside field, hills fading behind in evening lightLeisure

Holiday lodges, Wales

Refused once on noise, with eight objections second time round. The case had to not depend on guests behaving.

Read the case studyA single-storey community hall in a leafy residential street, with a larger period building alongsideResidential

Community building redevelopment, North West

The survey fell through on the day. Reporting that honestly was worth more than data we could not stand behind.

Sectors

Different sectors, different rulebooks.

Each of these was assessed against the standard the council or the assessor actually applies. What the building is decides which one.
