Unlocking a 5-Bed HMO in Brent

Strategic Planning Secures High-Value Conversion

Unlocking a 5-Bed HMO in Brent

Project overview

Client: Property Investment Manager

Location: Near Tunbridge Wells (Conservation Area)

Headline results

  • £180,000+ additional development value
  • Planning approved on first submission

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. Secure permission for the extensions first

2. Apply for the HMO change of use once 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.
