Working with Scenario Architecture to build a house West Sussex

Scenario is a boutique architecture studio focused on high-end House Building projects in and around West Sussex. Through our bespoke modern design service, we tackle projects of every scale and complexity, from new-builds and full renovations down to interior alterations and refurbishments.

Our highly skilled team can walk you through the steps required to build a house. We collaborate closely with our clients from the initial drawings, detail design and planning through tender and construction to the project’s successful completion. On time and on budget.

We use innovative 3D design and visualisation tools as a standard for all projects. Our experience shows that real-time visualisations and virtual reality are efficient tools for choosing finishes, fixtures and fittings, and simulating natural light. And our expertise with 3D building information modelling (BIM) technology produces reliable construction information, so all our project data comes from an accurate, coordinated 3D model. Using this cutting-edge technology collaboratively with consultants and contractors saves our clients time and money.

A Chartered Institute of Building case study featuring a Scenario project demonstrates the great benefits of this advanced technology for domestic architecture.

Architects in West Sussex In our clients words


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 designed a kitchen extension for us, and we are delighted with the results. The process was well organised, planned and delivered, and the whole team were a pleasure to work with. I would highly recommend them for their design, planning and project management skills.


Worked with these guys on the internal development of our office. From start to finish they were great. They got what we wanted first time and really made working with them very easy. Their aftercare has been great too helping us deal with something that they were not involved with in the first place. Will highly recommend them to anyone.

Architects in West Sussex >> Your West Sussex Project Further Reading

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.
