We are a pragmatic design led firm of Brighton Architects, with a combination of skills and experience gained through designing, funding, building and project managing difficult construction projects in Sussex and beyond, that has given us a holistic view of all the skills required to make a successful building.

Our work ranges from the smallest window replacement, through house extensions to commercial, residential, office and shops, on sites of up to 10 acres. Maximizing potential through intensive design to achieve schemes that are truly viable, we work closely with all parties to achieve high levels of approvals on Brighton, Hove & Sussex planning applications.

We know our designs result in added value and show you how in our project pages. We carry out work in and around Brighton, London and occasionally abroad from our own purpose built offices in central Brighton at 20 Regent Street.
Services
We design both new-build blocks of flats, individual houses, and small scale domestic conversions and extensions. Carefully designed and built small house conversions and extensions can transform the original building beyond the cost of the extra floor space. High levels of specification and detailed drawings help to get the result you want at a fixed price.
Our approach as an experienced Sussex conservation architect to all existing buildings is the same: To retain and repair the best of the original, and to contrast this with contemporary interventions where appropriate.
1. Ensure you are working with an RIBA (or at least ARCUK) registered Architect who will be qualified and insured. 2. Take time to create something that will last. Attention to detail makes buildings a success, financially and creatively. 3. Measure twice. Avoid site delays and unfortunate changes by basing the design on an accurate measured site or building survey.
The single most important component of sustainable, low maintenance, energy saving and environmental design is the material specification. Care and attention to detail, materials, workmanship and small scale design make the building a success. All of these photos here are from real projects that we have designed and built.
A thorough understanding of local and national government policies, procedure, and trends in planning informs our experience as architects for applications, and appeals. We work hard for high quality win-win solutions for clients, planners and the public realm in Brighton, Hove, Sussex, London and further afield.

I employed Domain for the entire project of my new build house which at the time was my garden. After an initial consultation with Duncan, I decided Domain were the Practice for me. Duncan took my initial idea right through to outline planning (including fighting a denied decision on appeal), design & specification, tender/selection of contractor, site visits/management of build/certification. I can't speak highly enough of Domain and from my experience I would definitely use them again for any projects in the Brighton area. They provide advice and hand-holding for all aspects of the entire project

We have just completed a great contemporary extension on a house in Haywards Heath for Domain’s
They provided the most detailed information that we have ever been supplied with, avoiding expensive delays and cost overruns on site that we so often encounter. We look forward to working with them again. Jamie@stylorenovations.

Gosh what a find. Duncan and all the team at Domain have been amazing. Within a very short space of time i have met them, discussed my plans for my grade 2 listed pub in a conservation area of Brighton, they have talked me through what will work and wont and have the plans drawn up ready for pre planning advice. Duncan's knowledge has been second to none and with Irene being a constant point of call i could not of been happier with the service so far. I look forward to moving my project forward with them on board.

Having worked with Duncan Thomas at Domain Architects on several projects over the past few years and including the very recent full redesign of my home, Duncan's attention to detail is first class, he and his team are truly professional, efficient and a pleasure to work with. I would have not hesitation in recommending Duncan and his team for design. Tom Pike, Ark Builders Ltd.
