Finding your dream home is a huge achievement. But a dream home rarely remains that forever. Over time, our lifestyles change and our homes must adapt. A 21st-century home must be all things to its owners: a place to work, to entertain, to raise a growing family and to grow older. If you don’t want to move, your home must improve.
A single-storey extension is a way around these changes in your life. Adding more space to the side or rear of your home – or both – is a necessary luxury that will work hard to play different roles as your needs evolve. A skilled architect with knowledge of your way of life, your future plans and your neighbourhood will help develop your space to accommodate your present and your future.
Your Single Storey Extension project
We launched Scenario in 2007 with a vision to adapt heritage architecture to 21st-century living. A highly functional home is the product of a deep understanding of the ways in which homeowners engage with their space. We work in close collaboration with our clients to make sure their needs sit at the forefront of every tailor-made design.
Our landmark project Scenario House demonstrates our commitment to the modern needs of homeowners today. The home was shortlisted for a RIBA London Award in 2018.

In our client's 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.
“Don’t move, improve,” goes the saying. And it works for most. If you love your location and find moving house a daunting proposition, there are measures you can take to expand and transform your existing home, and a single-storey extension is one of the least intrusive and least expensive options. These common home-extensions require fewer official hoops to jump through, less substantial foundations and minimal steelwork. And if they’re built well, they may also be able to accommodate a second-storey in the future.
At Scenario we design home extensions of every size and scope, within the planning constraints of the neighbourhood. We always recommend adding the most space to the home as permitted, without dramatically reducing the outdoor space. Generally speaking, the larger the extension, the more cost-effective it should be.
In a terraced house, a single-storey side-return extension is a popular way to gain valuable square footage and open up a warren-like layout. The addition of just a few square metres can allow for an open-plan kitchen-diner with a family room and separate bathroom and utility room that flows into the original lounge and hallway. A semi-detached house would benefit from a wraparound addition that occupies the side-return and reaches around into the rear garden. This would completely transform an old property into a functional home for generations.
Aside from space, one great advantage of a single-storey extension is the gaining of natural light. Single-storey additions can be glazed in any number of ways, from rooflights to Velux windows to bi-fold and concertina doors. Moreover, the redesigned layout will enable you to enlarge doorways and existing windows and push up your roof to allow in even more daylight. Enlarging windows and doorways also increases the sightlines throughout a home, making it feel bigger and safer.
If you have a garden, extending to the rear or side of your home creates an opportunity to connect indoors and out with walls of glazing and new flooring that can be carried through outside.
We also like to make sure a home-extension will allow the house to grow with the homeowners. As families progress and age, we expect generations to come and go, rooms to change function, bathrooms to work harder and people to require more assistance as they get older. This is where wider doorways, smooth transitions and large, highly functional kitchens and bathrooms to come in handy. After all, if you don’t want to move house now, you really won’t want to move house later.
Frequently Asked Questions
- 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.
