HAT Projects are architects, planners and enablers for built environment projects. We have a reputation for fresh and imaginative thinking, a collaborative working approach, and a rigorous attention to detail.

Our focus is on projects that make a difference – that respond to real needs, allow organisations to thrive sustainably, and create better and more beautiful public environments for all who experience them. We are practical as well as ambitious, and seek to maximize the value that good design and planning can bring, both financial and social.

Our design output is enriched by our work as policy-makers, community engagement specialists, co-designers, and self-builders; and vice versa. We work locally and nationally, from large to small projects.


Enabling and project support
We help organisations to develop projects from first steps, through workshops, brief-writing and user or community co-design. We can provide the early stage studies necessary to access funding for development work, and set your project on the right track from the start. If you are a community group, you may find the Community Projects Handbook that we produced for the GLA a useful resource.

Feasibility studies
The earliest stages of a project require holistic thinking that encompasses business planning, spatial analysis, and planning policy, as well as the creativity that reveals unexpected opportunities. As well as full feasibility studies, we offer quick capacity studies, condition appraisals of existing buildings, and planning advice to inform site purchases.

Architecture and landscape design
We provide full design services from feasibility and concept studies to technical design, overseeing construction, and handover support. We design landscape and public realm schemes, collaborating with other specialists to create sustainable, accessible and playful public spaces. Please note, we do not take on domestic extensions or small residential projects.

We provide advice on all aspects of planning, from site feasibility and allocations to listed building consents and other matters. We also work with local planning authorities to support plan-making and produce supplementary planning documents and design codes. We combine our expertise as architects and planners to develop holistic approaches, and have a particular interest in sustaining rural communities through sensitive and locally specific development.

Engagement, consultation and user research
We are specialists in community and stakeholder engagement which combines digital and in-person methods. This ranges from strategic stakeholder communications to user research, achieving unique insights into what communities really think and need. We provide training in community engagement, communications and design codes through national organisations such as Urban Design Learning.

Building and prototyping
We design & self-build small projects for locally based clients or community partners, working with an established group of local fabricators and trades as well as in our own workshop.


Our approach is always bespoke to the particular project, while underpinned by some key principles:

Developing a shared language with our clients and teams – understanding the project’s mission and values.

Clear and transparent communication with everyone involved - communities, clients, stakeholders, collaborators.

Challenging assumptions, bringing fresh ideas.

Working hard for our clients’ interests – budget, performance, long term value.

Meeting deadlines without cutting corners.

We are known for our creative intelligence and technical rigour, as well as our team leadership and working across complex multi-stakeholder environments. We have an excellent track record of delivering award-winning projects and initiatives, on time and on budget.

Our values

We consider environmental, social and economic impacts through all aspects of every project. We discuss carbon reduction at an early stage with every client, and always push for design approaches which minimise the lifecycle climate impacts of our projects, as well as designing for future resilience and adaptation.

We are active members of our community. We provide pro bono advice and support to charities and community groups - such as YES, Talawa, MS_UK, Age Concern and Hythe Forward. We sponsor the ID fund at Colchester Engagement & Next Steps, and many of our team are active in volunteering their time in different capacities.
