GUNN Associates






We subscribe to a vision of contemporary, contextual architecture, that exceeds our clients’ aspirations. We design with the intent that our schemes will be experienced by people for years to come, and we take that responsibility seriously.

We embrace technology to streamline our methods and make our service efficient for our clients.

In listening to, and understanding, our clients we form trusting relationships, allowing us to give professional advice that is personal to each client.

SH 170804_rra0265.jpg




To reach these ends we have a very simple process: we experience and analyse the site and its context; we listen to our clients; we understand the impact of our schemes; we act professionally and give good, considered advice. We are firm believers that we are always learning and that we should always listen and empathise with the stakeholders in our projects; this is how we develop and add value to our clients’ developments.



We work with our private clients to remodel and extend their homes; upwards, outwards, and down. We have extensive knowledge of householder and permitted development planning rules and advise our clients on how best to unlock the potential of their homes. We work with a range of expert consultants and suppliers to give the best, creative and professional advice to our clients. The project sizes vary from £500,000 to £2 million.


We work with developers and land-owners to maximise the potential of their sites. The developments range from 9 units to upwards of 50 units, and often include areas of other uses such as commercial, retail, and F&B.
We have excellent working relationships with a range of trusted consultants and suppliers and can advise on all aspects of these developments; from feasibility stage through to completion. We have developed an efficient and accurate site viability programme to assist developers and landowners evaluate their sites and this is offered at feasibility stage.


We work with our clients on their commercial projects such as office fit-outs, headquarters planning, and industrial commercial spaces. We liaise with landlords, commercial developers and end-users as the projects require.


We have worked with several higher and secondary educational establishments on the masterplanning and realisation of their capital projects. Our proven strategy is to embed ourselves into the culture of the client’s establishment, and this has shown itself to produce considered solutions appropriate to the budget and programme. We provide services including masterplanning and strategic programmes, bespoke design solutions, fabric surveying and maintenance programmes, and fire strategies. We communicate with governing bodies, management teams, and trustee boards, as well as landlords and estates owners. We work through all project stages from feasibility to completion.



Forming a cohesive team that supports our clients at all stages of their projects, each member of our team embraces learning, thought leadership, and creative problem-solving as the mainstay of our methodology.
