Our first priority is to define your needs and aspirations for your home or project. By working closely with you - using a variety of mediums and drawing techniques such as sketches, 3D modelling and orthogonal drawings - the ‘process of discovery’ begins and ideas are born. These sketch designs set up the parameters from which we progress to conversations with the Local Authorities in the form of a pre-application or full application.


It is fundamental for our team to design in collaboration with not only you but the entire project team, from design consultants and main contractors to sub-contractors and specialists. To ensure we produce high quality architecture, across all scales, a collaborative approach is key to every project. With an established network of consultants, contractors and specialists - alongside a strong portfolio - we have a well-practised and trusted team and can resource for your project, no matter its nature.
