Architects in West Sussex

West Sussex offers homeowners the best of village life and countryside, with easy access to London. Historic market towns, beautiful beaches, rolling hills and proximity to the Eurotunnel give the area a cachet that is hard to find in other parts of the country. The architectural landscape is a mixture of historic, half-timbered villas and modernised 20th-century homes.

Building, rebuilding or expanding a home in West Sussex requires adherence to local building regulations. This takes time and perseverance, but architects in West Sussex or London can help homeowners navigate the process.Scenario Architecture has been successfully piloting their clients through the planning process since we founded our practice more than a decade ago. Our experience for designing and modernising homes with compassion for the local vernacular has helped make Scenario one of the area’s most coveted residential partnerships.

Scenario was founded in 2007 with a passion for overhauling period architecture with striking contemporary design. We put our clients at the forefront of every design to achieve harmonious results – not only to look at but also to live in. A home that respects its past, present and future is the product of creative skill and a deep understanding of the residents. Scenario’s tailor-made homes tell the story of each owner – not about the architects.

Our landmark project Scenario House, shortlisted for the RIBA London Awards in 2018, is demonstrative of our fresh, customised approach and our commitment to the needs of today’s homeowners.

Buying a home in West Sussex means buying into an illustrious history dating back millennia. Abutting the sea and nearly entirely covered in green – more than half the area is protected countryside – it boasts Bronze Age burial grounds, Roman villas, Saxon lore and vestiges of Norman might. But its more recent history can be seen in the half-timbered Tudor-era houses and Georgian mills that dot the region.

Spectacularly undeveloped, West Sussex retains much of its Old World character, yet still sits largely within London’s commuter belt. Living here, a family can enjoy the best of the city while spending weekends at the seaside. Towns like East Grinstead connect to Central London and coastal cities like Brighton, with Gatwick Airport right down the road. They typically offer a mix of pretty, historic cottages and quiet clusters of mid-century homes, with ample properties into which to expand. Further south, towns like Worthing take on a beachy vibe with pastel-coloured Victorian terraces, turn-of-the-century bandstands and busy piers. Chichester, the county seat, revolves around a 12th-century Norman cathedral.

Families that expect to grow can find adequate space with the possibility to expand. Meanwhile commuting to London – whether for work or fun – is never entirely out of the question. Conversely, those who wish to leave London entirely for the allure of the sea can find it in places like surfer’s haven West Wittering.

People are attracted to West Sussex for more than just the clean air, proximity to the city and the lifestyle of farmers’ markets and craft beer. The potential of the existing housing is quite a draw. Just as West Sussex has a foot in the old and modern world, many homes here nod to the past while embracing the contemporary. The local vernacular style takes on a traditional silhouette, yet larger windows mean interiors get more natural light. It is not unusual for architects in West Sussex to build onto the original footprint with wide banks of glazing that give the rear aspect an altogether modern look. A good architect with experience in the region will be able to design around local planning restrictions and ensure the addition is acceptable to council officials.

The rear conservatory is a common home expansion move in West Sussex, but homeowners also choose to build up into loft areas and down into basements. Since the mid-century families have also come to the county to build anew. The area is open to new ideas, shapes, techniques and materials and it’s not unusual to find a striking façade of cross-laminated timber or white stucco among the traditional red brick.

Architects in West Sussex In our clients words


Great ideas and vision to help with our substantial improvement of a Victorian terrace. In our experience Scenario’s method prioritises the final result. That may mean more professional fees or higher quotes from contractors, as they understand the exact requirements.


Great, professional service. Good drawings and models and ultimately passed planning at the first attempt with Hackney Council. Would certainly recommend!


Scenario Architecture have created an outstanding design and space that was beyond my expectations. The design was through their unique process of understanding the client’s daily scenarios and collaborating with the client to come up with a unique design. The design process is one of the most memorable parts of the process and they also stretched my existing ideas to help create this unique space. A stress free journey throughout the whole process which Scenario were indispensable by giving advice on many difficult design and build decisions.


We wanted to renovate our house in a conservation area in central London. Given this involved a complete demolition and new build with an extra floor on top, getting planning approval was always going to be tricky. Scenario did an amazing job on the new house ‘envelope’ and throughout the planning phase. We couldn’t have wished for better from them and having succeeded in gaining planning approval owe them a very big ‘thank you’.


Scenario were great at thinking imaginatively and coming up with a design for a ground floor extension that was more ambitous than other architects we spoke to. They also helped us find a contractor who was able to complete the project working within timescale and our tight budget. I would recommend for mid to large sized projects with sufficient budget to allow for full utilisation of their creativity.
