Build

Brief Description of your project

Why us

ALL OUR PROJECTS REQUIRE QUALITY FINISHES 

By mastering best practices and applying them on every commercial and residential project regardless of the budget or size, we can ensure lasting quality. We believe luxury is about having standards and not cutting corners.

Our uncompromising aim is to deliver the highest quality projects on brief, on time and within budget. We treat every job as a luxury project, with the same approach and same team of experienced, trained specialists working across our sites.

BRIEF – We Begin by asking our clients to imagine their lives in the completed house and to describe their desired interaction with it. We then analyse these descriptions in detail to give us a highly defined brief. This brief is then converted into a 3-dimensional simulation which is both revealing and informative, illuminating aspirations, requirements and patterns of habitation.

FORM – From this base, the formal expression emerges, facilitating the requirements of each client’s unique brief. The resulting spaces are easily read as a resolution of the challenges presented by brief and context.

This methodical process strips the design of style and preconceptions, resulting in a completely bespoke and personal design.

MATERIAL – Only once the form and spatial qualities of the design are clarified, we ask: Which materials lend themselves effectively and sustainably to the realisation of the design?

We believe that architecture should provide the backdrop for life and not take centre stage. Life itself is in full colour, so materials are used in their honest, natural state.

A truly personal experience

Most architects and other companies which claim to be ‘design & build’ do not have the necessary in-house knowledge to accurately estimate the cost of a project until the initial design is complete. Usually, these companies rely on third party contractors to provide quotations which can result in budget creep, design amendments and delays. Our design & build process has been refined to deliver projects extremely efficiently with award winning results. Please feel free to contact us if you have a project in mind which you would like to discuss.
