About Scenario Architecture in London

When you own a home in London, you become part of the city’s long, distinguished history. When you make changes to that home, it becomes a part of yours. We launched Scenario in 2007 with a customised, out-of-the-box approach to modernising period architecture.

We collaborate closely with our clients because we know every scenario is different. The scenario dictates the flow, the fabric, the degree of luxury that makes a house personal, whatever the era or provenance. The scenario tells the story.

Our landmark project Scenario House helped established our practice among London’s top residential architects. Located in Stoke Newington, London, it showcases the potential of the city’s period stock to adapt to changing lifestyles with fluid lines, unusual angles and open spaces. In 2018, it was shortlisted for several prestigious prizes, including the RIBA London Awards.

Working together

Working with Scenario Architecture

Scenario is a boutique London architecture studio focused on high-end residential projects in and around London. Through our bespoke architecture service we tackle domestic projects of every scale and complexity, from interior alterations to full renovations and new-builds.

Our highly skilled team will take you step-by-step through every stage of the design process. We’ll consult with you from the initial drawings, through every design detail, steering you through local planning and tender. We’ll be present throughout construction and see you through your project’s successful completion. We always finish on time and on budget.

Founded by two London architects, Scenario prides itself on being a RIBA Chartered Practice. We comply with the strict criteria of the Royal Institute of Chartered Architects, meaning our clients are protected with insurance, health and safety measures and quality-management systems.

We have always been early adopters of the latest architectural technology. Our architects use innovative 3D design and visualisation tools as a standard on all projects – our experience has shown that real-time visualisations and virtual reality are most efficient tools for choosing finishes, fixtures and fittings, and simulating natural light.

We produce reliable construction information using 3D building information modelling (BIM) technology, so our project data derives from accurate, coordinated 3D models. Using this technology to collaborate with consultants and contractors saves our clients time, money and worry. This case study from the Chartered Institute of Building (CIOB), featuring a Scenario project, demonstrates the benefits of advanced technology for domestic architecture.

About the practice

Further Reading

Scenario is an established architecture practice focusing on contemporary residential design. We take on projects of every scale and scope, from home refurbishment, renovation and expansions to new-builds.

London is unique in its great selection of elegant period homes. Whatever your neighbourhood, you’ll find a stock of desirable homes dating back to the Georgian, Regency or Victorian era. Often, though, what these homes reflect on the outside does not compare to how they look on the inside. London’s strict conservation laws mean many buildings must maintain their architectural integrity on the façade. Yet details hidden from the street view are vulnerable to change. Over centuries, domestic London architecture has been subdivided, fragmented, modernised, replumbed and repaired – and not always compassionately.

That doesn’t mean a home with wonky floors, awkward functionality and obliterate period details cannot be salvaged. When looking to buy a home or trying to envision the future of an existing home, it’s always necessary to look past unnecessary walls and difficult corners to what a home can be. There is always new space to incorporate or dead space to recoup, whether in a dark loft, a rear kitchen, a stubborn side-return or barely-there basement storage.

Owners of London architecture must always be prepared to discover deeper problems throughout a renovation. Yet a problem in the hands of a good architect can often lead to a more beautiful and more efficient solution. Defunct electricals and obsolete plumbing can lead to smart systems that promise to save time and energy in the future. A troublesome roof can open up the possibilities for a roof of eco-friendly sedum or a bank of solar panelling. Remember when working out your remodelling budget that good design today may eradicate untold costs in the future.

It is possible to maintain the best period details like original mouldings, timber beams and gables while expanding Victorian and Edwardian homes – just as it’s possible to open up interiors to light and greater ease of movement and reintroduce an original fireplace or floor. New cutting-edge materials and a creative approach can help transform a period home not only for the way we live today, but for future generations. Prioritising good design, incorporating personal habits into the flow of your space and having a liaison throughout the process will speed up the process and eliminate any drama.

Renovating London architecture is more than a luxury in today’s landscape. Renovating well is a necessity for maintaining the rich architectural fabric of the city and housing large families in once-poky spaces. It reduces the need for new construction and cuts down on wasted energy in the long term. Most of all, improving your home goes toward building more beautiful, liveable London.

Local Architects

Taken in its entirety, London appears to have a range of wildly different architectural styles, dating back a thousand years and soaring overhead in futuristic steel and glass. Most Londoners, however, will recognise the residential architecture that flourished over a few hundred years. When London began to expand beyond the old city in the 18th century, after the destruction of the Great Fire had cleared the path to renewal, residential terraces appeared across town.

By the Victorian era, architects had perfected an attractive, accessible template for building family homes. They built thousands across the capital and the Edwardians added thousands more, which is why the style, structure and layout are so familiar to us today. These houses, and their surrounds, are a major element of the city’s history. If you live in London or the surrounding areas, chances are you have slept in, or are now living in, a home with this familiar heritage, in a neighbourhood that may go back even further.

Finding an architect who understands and respects this heritage is the key to updating a house with historical value, which is why you should seek out someone local to you. Local architects will have an appreciation for the neighbourhood and experience working within the parameters of heritage building controls. They may have relationships with local tradespeople and connections with council officials; knowledge of weather patterns, groundwater levels, sightlines and light; they’ll know how ambitious it’s possible to be in your specific area, and take you around to view similar homes in your area. Local architects may even have homes of their own nearby that demonstrate their skills and ambition.

To find local architects who might suit your project, start by asking friends and neighbours for their input. Their suggestions will be far valuable than an endless stream of Google data. Internet resources like Houzz (houzz.co.uk) and HomeOwners Alliance (hoa.org.uk) will turn up firms that operate near you, offer links to their work and provide tips for your first meeting.

Always consult the Royal Institute of British Architects, or RIBA (architecture.com), to look into architects you may want to work with. Make sure they’re registered as a RIBA-chartered practice and have experience working with planning authorities in the area. And then meet your makers. Chances are you’ll find someone inspiring and capable, who cares as much about your neighbourhood as you do yourself.

Architects near me

Moving house is a daunting prospect even before you consider the work yet to be done. It is increasingly rare, in and around London, to find a home that suits you and your family to a T. The longer you live in your new home, the more you’ll recognise what needs to change in order to live comfortably and efficiently for the long term. Finding an architect near you, who understands the architectural landscape you’re part of, is crucial for transforming your living space while adhering to local building regulations and fitting into the neighbourhood.

A good architect will understand the sacred nature of the built environment as well as the period look of your home. The job of a good architect is to accept these existing variables, and play to them in a way that will allow you to live a modern life in a period setting. This does not mean you and your architect will be working at cross-purposes. The charm of living in a place with history is embracing that history in a way that works for you. And the challenge is achieving a unique, contemporary space with nods to the past that succeeds without compromise. Architect and client should work in close conjunction from start to finish, on the same team. The sum should be greater than its parts.

Even a new-build home can sit happily within a neighbourhood with history if your architect understands the area, its people and the protectors from the local council. Within a reasonable envelope, with dimensions that respect local height caps and sightlines, interiors can take on all manner of styles. Bedrooms can be enlarged and reworked, or carved out under the ground. Extra bathrooms can be magicked from awkward corners; play rooms for children can emerge from lofty gables or expanded kitchens. Space can be captured from fallow driveways or rafters.

One of the drawbacks of a period home is the inevitability of dark, windowless spaces. A deft architect can work within the confines of neighbourhood traditions to draw in light with glass extensions and two-storey voids in the floor plan. They can introduce rooflights, clerestory windows or tempered-glass room dividers. At the same time, they can harness storage space in unused corners to give the illusion of open, minimalist living in a busy family home. In these ways, altering a heritage home in a conservation area can be as fulfilling as building anew.

Can I Convert My Loft Space?

If you are keen to make the most of the space in your home, you need to consider all the possible parts of it that you might be able to utilise. Many people with lofts in their homes have considered from time to time the possibility of converting it into something else - most likely a bedroom with an en-suite, or alternatively a study or working area. But can you do this with your loft space - and if so, what might be involved in the process?

The Benefits of Loft Conversions

First of all, let’s look into some of the main benefits you can expect to find from loft conversions. Generally, converting a loft will enable you to gain some extra space in your home without having to relocate, which can famously be a huge hassle. You might be growing your family and you feel you need an extra room, or you might be due to start working from home and you need an office. You might even just want a brand new, luxury bathroom.

With a well-designed and created loft conversion, your home can become a much more luxurious and comfortable place to live, and your quality of life can significantly improve. Of course, there is also the fact that you will likely be adding a considerable amount of money to the value of the home, which is great if you are thinking about selling at any point in the future (no matter how far down the line).

Analysing the Situation

If you want to convert your loft space, you will need to analyse the situation first, and see whether you are in a good position to do so. There are many considerations on this front, from budget to how much space you actually have up there, and you will find it is probably necessary to get in touch with a reliable and experienced architect, who can help you to work that out. With a proper analysis, you should be able to determine not just whether it is physically and fiscally possible to convert your loft space, but what kind of conversion you might be able to go for.

The Physical Space

One of the most important factors in any loft conversion, and the first thing you need to check out regarding the physical space itself, is the head height. You need to be able to comfortably stand up in there, or else it is unlikely you are going to be able to convert it into anything much. At the highest point of the loft, the lowest it should be is 2.3m/7.5ft, to ensure that it is high enough for you to actually live in. If there is just not enough headroom, there are ways around it - including lowering the downstairs ceiling a little. Of course, that extra work needs to be taken into consideration as well. Likewise, if you have a shallow-pitched roof, it is still possible to have your conversion carried out, but you will probably need a dormer window to make it work out.

As well as the height of the roof, you need to take a good look at its actual structure. Hopefully, what you have in your loft is a cut roof, along with attic trusses. This will ensure that the converted space is going to be as habitable as you would hope, largely owing to how much more open it is going to be. This makes the whole project so much simpler, as all you really need to do then is to install some reinforcement for the structure and build access to the space.

These types of structure are rare, however, especially if your home was built in the past 50 years. In all likelihood, you will have fink trusses, which are W-shaped and which are absolutely essential for the structure of the building. This does not in any way mean it is impossible to convert the loft - just that it will be a more significant job doing so. This is exactly why you need to hire an architect to help you design the space - they will already know exactly what needs to be done in order to convert the space safely and effectively.

The last thing you need to look into physically is the plumbing and electrics, although these days it is fairly straightforward to have these sorted for any space in the home. If you are keen to ensure that you are accommodating for this, however, it is wise to think about it early on and to get your architect to consider it too.

Building Regulations

As well as all of that, you need to make sure that what you have planned is actually legal. Much of this can be a real headache to figure out for yourself, so again you are probably going to find it a lot easier to speak to an architect, who will already know everything there is to know about these regulations and permissions that you need to abide by.

That being said, it is easier than ever before to convert a loft space and stay within regulations, thanks in large part to the changes to development laws that came in 2008. This means that it is very unlikely you will need to get planning permission for your loft conversion. Of course, the conversion still needs to comply with all remaining building regulations, as any form of extension needs to. With the right kind of professional help from an architect, you can ensure that this is the case. In particular, you need to make sure that the new space is protected from the home by half an hour’s worth of fire resistance. That will normally mean installing fire doors.

If you are keen on converting your loft space, it is perfectly doable, as you can see. But before you take another step forward, do make sure that you are seeking out the help and assistance of a professional and experienced team of architects, who can help you along the way.

Common questions

Your Questions Answered

How is Scenario Architecture different from other residential architects?

Scenario is defined less by a fixed visual style and more by how your project is understood, structured, and guided from the outset. We begin by looking closely at how you live and what your home needs to support over time, so the design grows from lived experience rather than from assumption or a preconceived aesthetic direction.

Our practice is also deliberately structured around specialist disciplines in creative design, technical development, and project leadership. That means your home is not only designed with ambition and care, but guided through every stage with clarity, rigour, and a level of oversight that helps protect the quality of the outcome.

Do you work on renovations as well as new-build homes?

Yes. We work across both the transformation of existing homes and the design of highly bespoke new-build houses. Our experience spans a wide range of house typologies across London and the Home Counties, including Victorian, Georgian, and Edwardian houses, terraced homes, locally listed and listed buildings, as well as highly sustainable new-build projects.

That breadth of experience means we understand the very different architectural, planning, and technical considerations each type of property brings. Whether you are reworking a historic home or creating something entirely new, we help you understand what is possible and shape a solution that feels coherent, intelligent, and specific to the way you want to live.

Can you help before I buy a property?

Yes. We offer a defined Pre-Purchase Service, giving you impartial expert advice before you commit to a property or move into a full design process.

This service can help you assess a property's potential, likely planning constraints, design opportunities, and the level of investment or complexity involved. The aim is to give you a more grounded understanding of risk, suitability, and long-term potential before major decisions are made.

Do you assist with planning permission?

Yes. Planning strategy is a central part of our early work because it shapes what is realistically possible on a site. We assess policy, context, site constraints, and the specific opportunities of the property before design direction becomes fixed, helping you move forward with a clearer understanding of what can be achieved.

We have an exceptional planning track record across historic homes, listed buildings, conservation areas, and other challenging planning conditions, as well as successful planning appeals. That experience allows us to combine ambitious design thinking with the strategic judgement needed to navigate complex approvals with clarity and confidence.

How long does it take to design and build a bespoke home?

Every project is different, but as a guide, the design and pre-construction stages often take around 8 to 12 months. That timeframe can vary depending on the complexity of the brief, the planning pathway, the nature of the property, and the level of technical development required before construction begins.

The construction period then depends on numerous variables, including scale, procurement route, site conditions, and the complexity of the work involved. Throughout the process, your Project Director plays a key role in managing and communicating programme clearly, helping maintain momentum, improve efficiency, and ensure you always understand where things stand and what comes next.

How do you help control construction costs?

Construction cost is managed from the outset, not treated as a one-off check later in the process. We keep a high-level overview of your budget from the earliest stages, helping align ambition, scope, and quality expectations before significant time or cost is committed. As the design develops, trade-offs are set out clearly so you can make informed decisions about where best to invest.

Your Project Director plays a central role in this. They help monitor cost movement, coordinate information across the wider team, and advise on how to maximise value from your budget based on nearly twenty years of professional experience in residential property. The aim is not simply to reduce cost, but to help you make balanced decisions that protect both design integrity and long-term lived value.

Do you offer support at strategic stages, such as feasibility, planning or tender?

Yes. Not every project requires the full journey from first briefing through to construction, and we can support you at key strategic stages where that is most useful. This may include feasibility, pre-purchase advice, concept development, planning, or technical information up to tender.

These packages are offered on a fixed-fee basis for transparency, so you have a clear understanding of scope and cost from the outset. We can advise on the most appropriate level of involvement depending on what you need, whether that is early clarity before committing further or support in moving the project to a defined milestone.

Do you design interiors as well as architecture?

Yes. Interior design is delivered in-house and forms part of one continuous design process rather than being treated as a separate layer. One of our designers is also a fully qualified and experienced interior designer, which allows interior thinking to be integrated seamlessly into the wider architectural process.

This means layout, materiality, lighting, storage, atmosphere, and furnishing direction can all be considered together rather than introduced later in isolation. The result is a home that feels more coherent and fully resolved, both in its overall spatial planning and in the details of everyday use.

How do you help manage the risk of building a bespoke home?

Building or transforming a home involves significant financial commitment and a level of complexity that many people encounter only once. We help manage that risk by bringing structure, visibility, and experienced leadership to the process from the outset, so key decisions are grounded in feasibility rather than assumption.

Planning context, likely budget range, technical implications, and delivery strategy are all examined early, before major commitments are made. As the project progresses, dedicated project leadership remains in place to coordinate consultants, clarify decisions, and help you retain confidence, visibility, and control as complexity increases.

How involved are you once construction begins?

Our involvement becomes more active during construction, because this is the stage where decisions carry immediate and lasting consequence. We coordinate the wider team, review progress on site, assess changes as they arise, and work to protect the design intent throughout delivery.

This ongoing presence provides continuity when complexity increases. With your Project Director maintaining oversight of programme, budget, buildability, and decision-making, you have a clear point of leadership throughout the construction phase and a process that remains carefully managed through to completion.
