First Floor

Background: The property was converted into five bedsits approximately 10 years ago. It comprises two bed/living

rooms and a shared kitchen on the ground floor, and three bed/living rooms and a shared bathroom on the first

floor. There are five single-person households.

Floor construction between the ground and first floor front bed/living rooms is approximately 200mm deep floor joist

at around 450mm centres with butt-edged floorboards over and a lathe and plaster ceiling. There is no insulation

material in the floor cavity. The partition wall between the unit being rated and the first floor rear bed/living room is a

single skin of plastered brickwork. The partition wall with the first floor front right bed/living room is a plasterboard

faced timber stud partition with no insulation material within the studwork. All internal doors within the property are

standard, hollow core, flush doors. The window to the dwelling is an original timber framed, single glazed, casement

in reasonable repair. The road in front is a typical suburban road and not a main thoroughfare.

Justification: Providing acoustic Insulation to the party floor and partition walls between adjacent dwellings to

current building regulation standard together with replacement of the standard hollow core doors with heavier half

Justification: The lack of any sound insulation to attenuate the transmission of sound between the different

bedsits substantially increases the likelihood of an occurrence during the next 12 months. While the bedsit is

located on the first floor it is inevitable that there will be different activities and lifestyles co-existing within the

property. The limited sound attenuation means there is a high likelihood of loss of privacy and disturbance from

normal domestic activities in the adjacent dwelling units. In addition, although remote from the bathroom and

kitchen, there will still be noise from the common landing and stairway. The likelihood of disturbance and stress

high.
