8-bed HMO and roof extension at 50 Shaftesbury Avenue, Southampton

Summary of planning committee decision

Decided by Southampton Planning and Rights of Way Panel on 2 Sept 2025.

25/00552/FULApproved

What was proposed

The application sought an eight-bedroom HMO, including a dormer roof extension, internal changes, cycle stores and retained bin storage.

“Proposal 2.1 The proposal is to change the use of the property to an 8-bedroom Sui Generis HMO including a dormer window roof extension which is of equivalent size to that which could be built under permitted development rights. The additional 2 bedrooms would be gained by creating 1 within a single-storey rear extension which has already gained approval via prior approval application ref: 25/00412/PAH and 1 within the proposed dormer roof extension.”

“Internally, the existing kitchen and dining room at ground floor would be knocked through into one open-plan communal space. The general layout of the existing bedrooms at ground and first floors and in the loft conversion will remain unchanged, but en-suite shower rooms are created for each bedroom and the two first floor bathrooms are reconfigured to provide a WC and communal laundry room.”

Officer report

The site and surroundings

The property is a semi-detached six-bedroom dwelling that has operated as an HMO, with parking, a rear garden and other HMOs nearby.

“Externally there is an area of hardstanding to the front and side of the property capable of accommodating at least 2 car parking spaces. A further area of gravel driveway runs along the side of the property leading to a large rear garden. The immediately adjoining property, No.52 Shaftesbury Avenue has an existing single-storey rear extension of a similar length to that recently approved for the application site under ref: 25/00412/PAH.”

“The majority of properties along Shaftesbury Avenue are similar large, semi-detached pairs or detached dwellings, many of which have been substantially extended. There is a rest home directly opposite the site with a large development of sheltered housing flats neighbouring this to the south. There are a number of existing smaller C4 HMOs nearby on Holyrood Avenue and 4 larger Sui Generis HMOs nearby at the top of Shaftesbury Avenue.”
