Where intelligent design
creates lasting value
Hosannahs is a UK architectural design and technical consultancy specialising in change of use, remodelling, residential development, HMO conversions, commercial-to-residential projects, extensions and Building Regulations design.
Our Story
We help homeowners, property investors, developers and asset owners understand what is possible, overcome planning and technical challenges, and transform underused spaces into practical, compliant and valuable places.
Hosannahs was founded in 2019 with a simple belief: clients deserve more than drawings. They deserve honest advice, thoughtful design and a clear understanding of the opportunities and risks within their project.
Those principles shaped the business at the beginning, and they continue to guide us today.
Since 2019, Hosannahs has grown from a small design practice into a multidisciplinary consultancy supporting projects across the UK. Our portfolio now ranges from home extensions and HMO conversions to complex commercial, residential, heritage and mixed-use developments.
Although the scale of our work has grown, our purpose has remained the same: to listen carefully, think commercially, design intelligently and treat every project as though the investment were our own.
What makes us different
We do not approach a project as a drawing exercise.
We consider the property, the planning context, the client's objectives, the available budget, technical compliance, construction requirements and the long-term value of the completed development.
By bringing feasibility, architectural design, planning and technical coordination together, we help clients make better decisions from the beginning. This can reduce avoidable redesign, duplicated professional fees, planning uncertainty and costly surprises during construction.
For a homeowner
that may mean creating a better home without moving.
For an HMO investor
it may mean achieving a compliant and efficient layout.
For a commercial property owner
it may mean giving a vacant building a viable new purpose.
For a developer
it may mean identifying hidden development potential before committing significant capital.
We are not here to sell clients the largest or most expensive proposal. We are here to identify the right solution—one that is thoughtful, viable and appropriate for the property and the people who will use it.
Our core values
The principles that guide every project we take on.
Honest Advice
We provide clear and realistic guidance, even when that means advising a client to reconsider, redesign or walk away from an unsuitable opportunity. Trust begins with honesty.
Intelligent Design
Every design decision should have a purpose. We aim to improve functionality, appearance, compliance and value—not simply produce drawings.
Technical Excellence
Good ideas must be capable of being approved and built. We combine creative thinking with careful technical information and regulatory awareness.
Commercial Awareness
We understand that property decisions carry financial consequences. We consider development potential, efficient use of space, buildability and long-term value from the outset.
People First
Behind every property is a person, family, business or community. We listen, communicate clearly and design around the people who will experience the finished space.
Responsible Transformation
We believe existing buildings should be reused and adapted wherever practical. Thoughtful remodelling can preserve character, reduce waste and give underperforming properties a valuable new future.
Collaboration and Accountability
Successful projects depend on coordinated people and reliable information. We take ownership of our role, work constructively with clients and consultants, and communicate openly throughout the process.
Our promise
Whether we are helping a homeowner extend a family home, an investor assess an acquisition or a developer transform a complex commercial asset, we bring the same principles established in 2019:
That is how Hosannahs began, how we have grown and how we will continue creating spaces and developments that deliver lasting value.
