Cahill Design Consultants (CDC) was appointed to carry out a noise impact assessment. This was to support the planning application for the conversion of the building housing “The Glory”. It was a public house/nightclub with disused residential flats above.
Prior to our appointment, “The Glory” venue closed down in search for a more up to date space. This provided flexibility to the freeholder. Now that the “Agent of Change” planning principle was no longer applicable, they could enhance the overall value of the site. The re-development proposals allowed for the refurbishment of the existing disused residential dwellings located on the upper floors. And the erection of new build additional apartments. This was alongside a total redesign and remodelling of the interior of the ground floor and basement levels. These levels used to house the public house/nightclub.
CDC undertook an in-depth noise survey at the site. This established the incident noise levels at the various residential facades, and the background noise levels outside nearby noise sensitive premises. In addition, a rigorous sound insulation testing regime was conducted. This established the transfer function of sound transmission from the ground/basement levels to the noise sensitive uses located above.
The results of the survey were used to model the sound insulation properties of the external and internal building fabric of the development. It also provided preliminary assistance for the design and layout of the various building services plant. The most critical was the new kitchen extract ventilation plant that will serve the remodelled ground floor commercial kitchen.
In order to provide confidence to the local planning authority, that the proposals can comply with national and local aims relevant to noise pollution, a series of design scenarios were developed and tested. This showcased to the decision makers how the building fabric can be designed for indoor noise levels to not give rise to adverse effects during whole house ventilation and during a possible overheating situation (in line with the requirements in Approved Document O).
The modelling of likely noise impacts from activities (including music playback at various levels) within the ground floor/basement was also undertaken. This showcased the range of potential uses in the space alongside a review of the available noise control measures that can be utilised to support various uses.
The acoustic consultancy services offered by CDC provided the necessary acoustic strategy for the development proposals. Ensuring that the two uses (commercial/residential) can harmoniously co-exist in the same building. This also ensures future occupants of the residential apartments are protected from the harmful effects of noise pollution.
