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

FAQWhat is the cost of building a new house?
If you are thinking about building a new house from scratch for which the term Self Build is often used, we currently recommend allowing between £2,500 and £3,500 per square metre for projects in and around London. This may sound like a very wide range initially, perhaps too wide to be useful? As soon as we can establish even a few of the basics of your requirements and aspirations for the project we can safely narrow it down and customise it to match your intentions. The key parameters that will help us to refine initial estimates are whether or not a basement is required to achieve your target floor area, the likely construction method and corresponding structural approach and of course your desired level of fixtures, fittings and material finishes. Another key parameter that we must consider right from the outset is the level of sustainability that we are aiming at, are you satisfied with the base line requirements as defined by current building regulations, or should we aim higher? Working together with sustainability experts we have created our own bespoke set of sustainability packages which allows you to place your sustainability target anywhere you wish. This can range from basic compliance to an extremely sustainable and energy efficient standard which comes with great savings on running costs, future proofing and wellbeing benefits such as improved air quality, thermal comfort, and considerate and healthier surface finishes.

FAQWhat is the cost of an internal refurbishment?
Currently we recommend allowing between £2,500 and £3,000 per square metre for areas which will undergo an extensive renovation. We designate an area of the project as extensive renovation if the planned works includes substantial changes to layouts, significant structural works, re-plumbing, re-wiring and full redecoration. For areas of lighter internal renovation which do not require significant changes to layout or substantial structural works but do require full redecoration, re-plumbing and rewiring, we recommend allowing between £2,000 and £2,500 as an estimated cost per square metre, we designate these areas as requiring medium renovation. If there areas in your project which only call for a light renovation such as re-plastering, and painting, installing new floor finishes and light modifications of electrics and plumbing fittings, we will designate these as areas of light renovation and recommend that you allow £1,500-£2,000 per square metre or even as low as between £1,000-£1,500 if you only have light touches in mind. The real cost for your project will depend on several different variables including the complexity of the design, extent of structural works and level of fixtures, fittings and material finishes. These estimated costs per square metre are for the build cost excluding VAT and professional fees.

FAQWhat is the fee structure used by Scenario Architecture?
The fee structure that we will offer will depend on the type and scale of your project as well as the scope required from us. The vast majority of the projects we take on are what we call ‘full projects’, these are projects for which we will provide full Architectural services from inception to completion, covering the standard scope of services offered by most RIBA Chartered Architects and more. For these full projects our fees will be calculated on the basis of an agreed percentage of the final cost of the building works exclusive of VAT and professional fees. At any given time, we will calculate our fees based on the latest construction cost estimates available until the final cost of the building works has been ascertained. Our fees will be adjusted both forward and retrospectively to reflect any increase in budget and scope of the project, and forward only (due to work already completed) to reflect any decrease in budget/scope. During early stages, our fees will be calculated based on our in-house estimation tool and once available, on estimates by the appointed Quantity Surveyor, followed by actual prices of returned tenders and finally, the contract sum reflecting any changes during construction. Under unusual circumstances we may agree to take on projects only up to a certain stage, for example up to planning, and sometimes from a certain stage if we are taking over from another Architect. For these ‘partial scope projects’ we will normally put forward a simple fixed lump sum proposal.

FAQWhat is Scenario’s approach to planning?
Planning in the U.K in general and in Greater London in particular is admittedly a tricky business. It is a complex maze of policies, standards and regulations that requires specialised and up to date knowledge and skills to navigate successfully.  Over the years we developed a strong approach and an effective methodology, allowing us to maintain an outstanding track record stretching over more than a decade. Successfully securing planning permission for our clients across Greater London and the Home Counties.  The key aspects of our approach to planning are listed below: 
  • Collaborative – We start the conversation with planners early and advise most of our clients to seek pre-planning advice prior to submission of a full planning application. Our experience shows that when properly consulted and liaised with, most planning case officers will be receptive to conduct a professional dialogue, increasing chances of successes. 
  • Strategic – We tailor a custom planning strategy for each project based on its circumstances such as planning history, local context and specific challenging elements. We sometimes split applications or introduce minor tweaks to the scheme during the consideration period in conversation with the officers to prevent one contentious element from jeopardising approval of the main scheme.
  • Professional – Our experience shows that the quality and clarity of the submission in terms of background research, planning history of the property and context, precedent and of course the arguments presented to support the case has a tremendous effect on success rate.

FAQWhat is Scenario’s approach to sustainability?
In the past, it was common practice for local authorities to impose sustainability standards on residential developments. However, the 2015 Deregulation Act removed the obligation on local authorities to require any standard at all, which means the only requirements having fallen back to those of the Building Regulations.  With no clear and improved targets to work towards, in collaboration with Envision (, we have created optional Sustainability ‘Levels’ to offer our clients the chance to drastically improve the sustainability credentials of their home. These ‘Levels’ encompassing Bronze, Silver, Gold and Diamond, traverse a clear and applicable route from basic compliance with current Building Regulations all the way to the full and rigorous HQM (Home Quality Mark) certification within Level Diamond. As the packages become more elaborate in terms of sustainability, analysis and implemented measures, they provide increasing tangible benefits. Ranging from thermal and acoustic comfort and wellbeing, to reduced carbon foot print, savings on running costs and significant advantages through the planning process.  The more elaborate packages obviously entail higher cost in terms of professional fees as well as impact on the construction cost, although each sustainability ‘Level’ will endeavour to not overly burden the construction budget.

FAQWhat is unique about the Scenario design process?
The scenario design process was developed, tested and perfected through over a decade of extensive delivery of residential projects within and around London, some of its key features are listed below:   
  • Scenario based design – We start each and every project with a meticulous analysis of our client’s vision, requirements and aspirations. We do this by asking our clients to imagine their everyday scenarios living in the completed house and describe their desired interaction with it. 
We then translate the resulting high definition brief into an informative and revealing 3-dimensional simulation, illuminating aspirations, requirements and patterns of habitation. 
  • Uniquely interactive - Our client’s deep involvement in the process does not stop with completion of the brief. Our design meetings are highly interactive, informal and fun. 
Sitting together in front of a real time 3D model of the proposed design with realistic materials, lighting and textures we push and pull the proposed scheme together to explore its full potential and drag and drop different materials to explore various options. hen we invite our clients to take a virtual reality tour through advanced equipment that is always available in our practice for our clients to explore their projects at different stages of development. 
  • Designed to reflect you – Based purely on your lifestyle, aspirations and requirements and free from externally imposed concepts, metaphors and pre-conceptions, a completely fresh and unique design will gradually emerge and it will tell your story not ours. 
It will not look like an image cut out of a trendy architecture magazine and not designed to intentionally impress anyone. It will feel familiar, warm and inviting and you will recognise yourself in it because it will be a genuine expression of the unique way in which you and your family wish to interact with it and enjoy it for many years to come.

FAQWho will be assigned to work on my project?
Any architectural project comprises three main aspects, Creative design, Technical design and Project Management. A successful architectural project can only be achieved when all three aspects are properly performed and harmoniously integrated by an experienced professional. But can we really except a single person to specialise and shine in all three aspects and furthermore skilfully negotiate and balance the often contradictory challenges these aspects present? The basic assumption underlying the common structure of almost all other architectural practices today is that it is possible and this is precisely what is expected from the lone and often junior Architect that would typically be assigned to run your project start to finish. Scenario works in a completely different and new way, we believe in specialism and teamwork and therefore assign three experienced specialists for each and every project. A project team in Scenario is composed of a Project Director, a Designer and a Technical Designer, seamlessly collaborating to deliver results, which are noticeably superior to anything that a single person, skilful as they may be, could ever produce.
