Overview
A prior approval application was successfully secured for the conversion of an existing office building into two residential dwellings at a prime town centre location in Horsham.
Submitted under Schedule 2, Part 3, Class MA of the General Permitted Development Order (2015), this project highlights how a strategic planning approach can unlock value and accelerate delivery.
The Opportunity
With shifting demand in the commercial market, this underutilised office space presented a clear opportunity to unlock residential value in a highly sustainable location.
Our approach focused on maximising the site’s potential while minimising planning risk and delay.
- Repurpose vacant/underused commercial floorspace
- Deliver two high-quality residential units
- Contribute to local housing supply without requiring full planning permission
The Proposal
The scheme delivered:
- Conversion of existing office space into two high-quality dwellings
- Efficient internal layouts designed for modern living
- Minimal external alterations, reducing cost and programme risk
- Conversion of existing office accommodation
- Creation of two self-contained dwellings
- Retention of the existing building envelope (minimising construction impact)
The design focused on efficient internal layouts and compliance with space standards, while ensuring a suitable living environment for future occupants.
Planning Strategy
We utilised Class MA permitted development rights to avoid the need for full planning permission, significantly reducing both timescales and uncertainty.
Our strategy focused on proactively addressing key technical considerations, ensuring a smooth and robust approval process.
Key planning considerations addressed included:
- Transport and highways impacts
- Noise impacts on future occupiers
- Natural light provision
- Contamination and environmental constraints
Key Condition
A condition was attached requiring:
- Submission and approval of a sound attenuation scheme prior to commencement
- Implementation of the approved measures before occupation
This ensures acceptable living conditions for future residents and aligns with local planning policy.
Outcome & Value
This project demonstrates how the right planning strategy can:
- Unlock hidden value in underperforming assets
- Deliver consent quickly through permitted development rights
- Reduce planning risk and improve certainty for developers
- Accelerate the transition from concept to construction
- The effectiveness of Class MA permitted development rights in unlocking residential schemes
- A streamlined planning route with reduced risk and timescales
- The viability of converting town centre office stock into housing
Conclusion
This approval showcases a clear, commercially focused approach to planning and turning underutilised space into deliverable residential units with speed and certainty.
By combining technical expertise with a strategic use of permitted development rights, we help clients unlock opportunities and move projects forward with confidence.
