The application proposed the change of use of 16 Derrick Avenue, South Croydon CR2 0QL from a C3 dwellinghouse to a C4 House in Multiple Occupation accommodating six people, together with conversion of the garage into living accommodation. The property is a semi-detached four-bedroom family dwelling with kitchen, lounge and garage. Derrick Avenue is a quiet residential cul-de-sac with a 3/2 PTAL rating — indicating low public transport accessibility.
Our client was the adjoining semi-detached neighbour, whose property shared a party wall with the application site — placing them in the most directly affected position of any objector.
Derrick Avenue is a cul-de-sac composed entirely of family-sized dwellings. Croydon's Strategic Housing Market Assessment identifies the retention of larger homes as a strategic priority, and the council's housing policies specifically seek to prevent the conversion of family homes in areas of high demand. Derrick Avenue, with its proximity to good primary schools and green spaces, was precisely the type of location where demand from families was greatest. The loss of one of the cul-de-sac's family homes to a six-person HMO was a significant planning harm that the applicant had not justified.
Policy DM10 requires the council to consider the effects of noise, refuse collection, and additional parking on the character of the area. Six occupants — potentially with individual work schedules, social patterns, and vehicle use — generate materially more activity than a family. The comings and goings on a quiet residential cul-de-sac, at all hours, would be directly audible to the neighbouring semi-detached property. The party wall between the two properties meant noise transmission from the HMO's communal areas, kitchen, and individual rooms was an acute concern.
We challenged the adequacy of the proposed internal layout for the wellbeing of six HMO occupants. The proposed kitchen was insufficient for six people and the application made no adequate provision for communal living space. The applicant's planning statement appeared to suggest that residents would use public parks for socialising — an unrealistic and unacceptable basis for assessing the adequacy of the proposed accommodation. The reliance on external public space to compensate for inadequate internal communal facilities was contrary to good standards of residential accommodation and the occupants' wellbeing.
At PTAL 3/2 — indicating low public transport accessibility — six occupants at this location would have a realistic expectation of car ownership. The conversion of the garage into living accommodation removed the only dedicated off-street parking provision from the site. The resulting demand would fall entirely on Derrick Avenue's on-street capacity, which as a cul-de-sac serving exclusively residential properties had limited tolerance for additional pressure.
Croydon Council refused the application. The loss of a family-sized dwelling on a family-only cul-de-sac, the demonstrable harm to neighbourhood character, the inadequate internal facilities, and the parking impact were collectively determinative. Our client — the immediately adjoining semi-detached neighbour — received the direct protection they sought.
