Stitch is an award-winning studio of architects and urban designers established in 2012. We are experts in housing and regeneration and we have achieved unanimous planning consent for over 1200 new homes in London, with nearly 300 of these homes now complete and hundreds more under construction.

Our projects range from urban design strategies and masterplans to detailed planning applications for complex urban sites. Our clients are private developers and housebuilders, housing associations, local authorities, and most recently special companies established by councils to deliver their own housing.

Every place tells a story

Our ethos is to continuously combine architecture and urban design so that every place can tell a unique and compelling story. Working with stakeholders and communities is a particular strength of the team. We are adept at balancing the aspirations of different individuals and groups and finding a path that will be a best fit for all stakeholders’ aspirations.

Commercial awareness and added value

Through decades of combined experience the team has an excellent awareness of commercial drivers affecting the delivery of complex urban schemes. We apply this knowledge and expertise to every project at every scale – from outline masterplans to detailed proposals. We add value by designing highly efficient buildings, releasing budget for the design details that make each scheme unique.

Where we come from, where we’re going

Sally Lewis founded Stitch in the belief that seamless, integrated design across the scales makes the best places. She is an architect and urban designer and has 20 years’ experience working with private and public sector clients, developing a specialism in large-scale urban regeneration projects. Under her leadership Stitch has grown from a small start-up to a well-respected and established practice delivering some of the largest regeneration schemes in London.

A leading role

It is our vision to play a leading role in creating the great housing that London needs, and in doing so making streets and neighbourhoods that each have their own unique story, to be cherished for generations.


Stitch is an RIBA Chartered Practice

Here’s a film we made about how we see things.



Stitch by name, stitch by practice

We pay loving attention to strategy and detail all the way. We are architects and urban designers but there are no divides in the team. At Stitch nothing falls through the gaps. This shows in our work.

Through our commitment to collaboration and partnership working we have had stakeholders on board for every regeneration project in the past 5 years. With our story for every place approach, we win hearts and minds every time.
