Major Castletown Site Could Be Transformed Under New Proposals

Plans have been unveiled to redevelop a long-derelict former Royal Navy accommodation block on Portland into around 360 new homes.

The proposals, brought forward by Comer Homes, focus on the former Hardy Complex site in Castletown and are now being shared with the public as part of a consultation process. The first of two drop-in sessions is taking place today.

 

The scheme would see the existing Hardy Block demolished and replaced with a new residential neighbourhood on the brownfield site.

 

Developers say the plans include a mix of around 360 properties, ranging from apartments and duplexes to terraced houses, mews homes and detached properties.

 

The Hardy Complex has remained empty since the mid-1990s after being vacated by the Royal Navy. Over the years, it has become a hotspot for anti-social behaviour, with reports of people regularly gaining access to the site.

 

Comer Homes purchased the site in 1999 and previously secured permission to convert it into luxury apartments, although that project was never carried out. A neighbouring building was later developed into what is now known as Atlantic House.

 

According to the developer, the new plans have been designed to reflect the site’s steep terrain and take advantage of views across Portland Harbour and the Jurassic Coast. The masterplan divides the area into four distinct sections, each responding to different aspects of the landscape.

 

The development aims to retain as much open and green space as possible while making use of existing infrastructure. Proposed building materials include Portland stone, brick and render.

 

Brian Comer, Chairman of Comer Homes, said the site presents an opportunity to replace a prominent derelict building with a “vibrant new neighbourhood” that reflects the surrounding coastline.

 

Dorset Council leader, Cllr Nick Ireland, described the site as a key location for Portland and said bringing it back into use could play an important role in the area’s regeneration. He urged residents to take part in the consultation and help shape the future of the site.

 

South Dorset MP Lloyd Hatton has also called for the building to be demolished, describing it as an eyesore. He said he would continue working with the developers and council to ensure the site is redeveloped, with a focus on delivering affordable housing for local people.

 

Residents are being encouraged to attend the public exhibition to view the proposals, speak to the project team and share their feedback.
