Frequently Asked Questions

Common questions about our change of use, planning and architectural design services.

Hosannahs is a UK-wide Change of Use and Remodelling specialist providing planning, architectural design and Building Regulations services. We help property owners, investors and developers unlock the potential of existing buildings through commercial-to-residential conversions, HMOs, residential remodelling, mixed-use and heritage projects.

We work with existing buildings that have the potential for a new use or greater value — including offices, shops, warehouses, pubs, hotels, care homes, HMOs, residential properties, churches, community buildings and listed or heritage properties. From commercial-to-residential conversions and HMOs to mixed-use, heritage and residential remodelling, we provide the planning, architectural design and technical expertise to help unlock each building's potential.

A change of use application is required when you want to change how a property is used—for example, converting a commercial building to residential, or a house to an HMO or Airbnb. We specialise in these applications and guide you through the planning requirements.

A standard planning application typically takes 8-13 weeks for a decision from submission. We handle the entire process including preparing drawings, submitting the application, and liaising with the planning authority. Our 98% approval rate means your project is in safe hands.
