Case study

The challenge

A long-held rental property had unexpectedly become vacant following the departure of a sitting tenant. Located within an Article 4 area restricting HMO conversions, the investment manager assumed the property could only be re-let as a single-family home — severely limiting its potential return.

With the asset underperforming and planning restrictions appearing to close off redevelopment options, the opportunity to unlock additional value seemed unlikely.

Our strategy

Following a detailed review of local planning policy, we identified a viable pathway to secure permission for a 5-bedroom HMO, while also maximising the site through first-floor and roof extensions.

To strengthen the planning case, we advised a phased application strategy:

1. 1. Secure permission for the extensions first
2. 2. Apply for the HMO change of use once the additional space was approved

During the application process, we engaged directly with the council to address emerging concerns. By presenting robust planning arguments and policy evidence, we successfully overcame objections that could otherwise have led to refusal.

The outcome

Planning permission for the full 5-bedroom HMO conversion was granted on the first submission.

The change of use unlocked over £180,000 in additional gross development value, transforming a low-yield asset into a high-performing investment. Breakthrough Planning's fee represented less than 2% of the additional value created.

Client feedback

“Two other firms turned this down. Breakthrough Planning not only took it on — they secured two major extensions and approval for a 5-bed HMO in an Article 4 area. The additional value created dwarfs their fee. They're now our go-to consultants whenever a project looks complicated.”
