Architect Wandsworth

The virtues of Wandsworth are something of a best-kept secret in London. Its neighbours Battersea and Wimbledon get more attention, and when you do hear about the small South London enclave, it owes more to the infamous prison, or that a scene from Clockwork Orange was shot in a gritty underpass near the Thames. Yet Wandsworth’s slender streets, edged by wrought iron gates and flowering trees, are some of the loveliest in London. Surrounded by outstanding schools, rustic public parks and the trickling River Wandle, it’s like a private island of contented living.

The Victorian houses of Wandsworth are some of the most unique in the city, with unusual gables, pediments, finials, fanlights and covered porches. Sat in a quiet enclave near the River Thames, interspersed with independent shops and pubs, these elegant terraced homes come available less frequently than nearby Fulham or Clapham. And when it comes to building work, they require the wisdom of an architect to carry out works to code.

We launched Scenario in 2007 with a specific architectural vision for modernising heritage property – and building anew. Our work places emphasis on the homeowner. We collaborate with our clients from start to finish, taking into account their way of life to produce functional, tailor-made architecture.

Our landmark project Scenario House was shortlisted for several prestigious architecture awards – including the 2018 RIBA London Awards. It demonstrates our successful approach to domestic architecture projects. Other Scenario projects have featured in Elle Decoration, Dezeen, Houzz and Ideal Home.

Victorian houses account for one sixth of all British homes. With their limited kitchens and cosy rooms, expanding them has become de rigueur. Victorian extensions are common practice around the country and especially in central London, where homeowners seek extra space in tightly regulated areas by moving into the loft and side return.

Most contemporary architects have worked out space-saving and space-enhancing solutions that can be replicated from house to house. The loft extension, side-return extension and basement excavation have become commonplace moves across the capital and the Home Counties. These strategies are popular because they work to expand a house when a family needs it and bring in valuable natural light. At Scenario, we use up-to-the-minute technology to recoup space and expand in all directions. We maximise hidden corners under stairs and in the eaves. And we find ways to improve the flow of a home that incorporate unusual angles and silhouettes.

An extension of only a few metres can open up a space dramatically in many cases – particularly if there is a creative design behind it, integrating the adjoining rooms. Expanding into a side-return or rear garden can make an eat-in kitchen from a galley, or contribute to a so-called great room in the place of a smaller, darker layout. The removal of a structural wall can allow for a kitchen island where counter space was lacking, and often enough space to incorporate an office nook. In the Victorian terraced houses found around Wandsworth and elsewhere in South London, a side-return extension has great potential for a major lifestyle change.

Ditto a loft conversion. The loft is already there. Opening it up with dormer windows or by lowering the floor slightly avoids increasing the roof volume beyond the regulated amount. And yet it will transform an unused void into up to two bedrooms and a full bathroom. Suddenly a couple or their children can co-opt an entire floor for themselves, or relegate the space for guests.

Scenario Architecture tailors all our residential projects to the lives of the homeowners we work with. Just as no two families are the same, no two kitchens, bathrooms or wardrobes should be. We consult with our clients every step of the way to make sure the way they live, work, sleep, cook, dress and play is reflected in their environment. For this reason, every one of our designs has a different look and flow. So on the outside, you may recognise the house as Victorian, but inside, you won’t recognise it as a Scenario House.

Applying for an extension in a London conservation area should be fairly straightforward, as long as your project complies with the neighbourhood elevation and footprint. An architect, Wandsworth based, can undertake a Building Regulations application for you, ensuring your design complies with the local fire-safety, ventilation, plumbing and structural standards. We at Scenario have fostered relationships with most building and planning commissions across London and we often tackle these responsibilities for our clients.

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.

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.

FAQHow long will it take to obtain planning permission for my project?
The standard consideration period for a residential project is eight weeks, this is the official time frame for your local council to carry out consultation with the neighbours and reach a decision.  We recommend allowing for a minimum of ten weeks from submission to decision as in practice the process always takes slightly longer for the following reasons: 
  • The decision period clock only starts ticking once the application is validated by the Council, This requires then to check that the forms are completed correctly and that the submission contains all the necessary drawings, statements and reports.
Validation can take anything from a few days to couple of weeks when the council is very busy, which is most of the time…
  • Although required by law to provide a decision within the statutory eight weeks period, it is not uncommon for councils to miss the deadline of the consideration period, normally only by a few days, sometimes longer. 
While there are some effective measures to apply pressure, which we do not hesitate to use when appropriate, it is generally beneficial for the project to bear with the council a little longer. 
  • In some cases the council may ask us as your agent for an extension of time, this may be requested due to internal reasons or as an acceptable result of a professional discussion that we are conducting with them about certain aspects of the application that they are not sure about.

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 the cost of building an extension?
Currently we recommend allowing between £2,500 and £3,000 per square metre for side extensions, rear extensions or front extensions. For basement extensions, which are most expensive way to add space to your home, we recommend that you allow between £3,000 and £3,500 per square metre. When it comes to roof extensions, our experience shows that it is better to allow a lump sum of £40,000-£60,000 for loft conversions with dormer windows and between £80,000 and £120,000 for mansard roof extensions. These ranges are based on averages from numerous actual projects that we have completed in and around London since we established Scenario in 2007. We only use these rough costs per square metre during the early stages of design to maintain awareness of your target budget until a cost professional is appointed and more accurate methods of estimation are employed. The actual cost for your project will depend on many factors, including the complexity of the design, level of structural support required, and selection of fixtures, fittings material finishes. Using these rough ranges as a guide we will work together with you in an interactive process to optimise budget and scope and find the balance that works best for you. The estimated costs per square metre mentioned above are for the build costs only and exclude VAT and professional fees.

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 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.
