We established Scenario in 2007 with a vision to maximise living spaces to their greatest potential. Our boutique practice takes a considered, collaborative approach to our clients’ habits, hobbies and aspirations, delivering contemporary home extensions that tell a story about the owners – not the architects.

Working with Scenario Architecture on your house extension project
Scenario is a boutique architecture studio focused on improving homes with spacious, contemporary extension projects across London and beyond. Through our bespoke architecture service, we tackle projects of every scale and complexity, from modest single-storey extensions to side-return extensions project, basement extensions, loft extensions and rear house extensions project.
Our highly skilled architects can take you step-by-step through the challenge of building a house extension. We’ll collaborate closely with you from the initial drawings, detail design and planning, guiding you through the tender and construction process and completing your house extension on time and on budget.
Early adopters of the latest drafting and building technologies, we use innovative 3D design and visualisation tools as a standard for all our house extensions. Our experience has shown that real-time visualisations and virtual reality are extremely efficient tools for choosing finishes, fixtures and fittings, and simulating natural light.
We use 3D building information modelling (BIM) to produce reliable construction information, so all our project data comes from an accurate 3D model. Using this technology collaboratively with consultants and contractors is proven to save our clients time and money. This Chartered Institute of Building case study featuring a Scenario project demonstrates the benefits of this advanced technology for house-extension projects.
Scenario Architecture is a RIBA Chartered Practice. We comply with all the criteria of the Royal Institute of Chartered Architects, covering insurance, health and safety and quality-management systems.

There are few world-class cities where you can own your own house and convert it for your needs, and none as exciting as London. The city’s rich stock of residential housing has great potential for improvement. If you already own property in the capital and can’t justify the costs of moving house, renovating and extending your existing property may be the right move for you. Best of all, you’ll be able to stay in the neighbourhood you know and love.
Strict planning regulations in neighbourhoods rich with heritage housing make house extensions a challenge for some. Seeking the help of an architect, rather than going directly to a standard-issue builder or home-extension specialist, means the specific character of your home will be respected and enhanced. An architect will unlock potential and use materials in an original way that can complement your home’s historic appeal.
Once you’ve found an architect whose style and personality balance your own, the process of transforming your home will fall into place. Together you can collaborate on tailoring the original bones to your personal lifestyle with detailed specifications, starting from the party walls inward. Even if planning regulations are stringent in your neighbourhood, you’ll usually be able to extend outwards at least enough for an extra room or two – taken from wasted outdoor space, eaves in a pitched roof or awkward corners you didn’t even know you had.
You could extend a kitchen to incorporate an eat-in breakfast room, add an en suite bathroom, a bedroom for a new child or a home office. In a neighbourhood with newer housing stock, like a London suburb or brownfield development, more involved home extensions may be possible, like wraparounds incorporating a side return and rear, a second storey, garage topper or double-height rear extension.
House extensions are carried out in a more compassionate way today than they’ve ever been, and a good architect will strive to preserve original architectural elements – like decorative cornicing, ceiling roses, skirting boards, dada rails and picture rails – while giving your home the modern openness so many desire. Pivoting doors and Crittall-style steel windows are brilliant complements to period decorations and antique brick.
Once you’ve committed to the process, a house extension will make additional changes easier and less cumbersome, like new sash windows, flooring or a fresh paint job. They could be done concurrently with the structural work, pull everything together and help you get a good-as-new home that works with your unique way of life.
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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Our experience shows that planning officers respond better to projects when they feel consulted and collaborated with. We find that when we truly listen to their often helpful and valid feedback and treat them as consultants for the projects and not representative of an evil enforcing authority, they tend to collaborate well with us and demonstrate increased flexibility.
- Although the council in theory have eight weeks to consider your application, in practice they are constantly overloaded. They will only look at your application in the last few days of the consideration period. If this is the first time that they come across a scheme that they were never consulted about, our chance to secure permission for you in a single attempt is significantly compromised.
- The standard practice is for the council to consider the full planning application as submitted and then issue a yes or no decision. Case officers are not required or even encouraged to enter a discussion with us or accept resubmission of minor changes to the proposed scheme during the consideration period.
