Square Peg Bureau

about us.


spb was founded in 2016 by Tom Irwin after 15+ years gaining valuable experience at large commercial practices such as CZWG Architects and PDP London, with the desire to bring a rational and simple approach to both design and practice.

We are an ambitious and client-focused practice, specialising in producing innovative solutions to complex sites. 

We strongly believe in the benefits of a healthy balance between work and life, and bring this ethos into our designs.

We believe, first and foremost that a building must function for the intended user. However, this does not mean compromising on form. A well designed and delivered project can create a positive environment for both current and future generations. 




1. Viability Studies

To start a project, there must be an awareness of the opportunities and constraints. This enables a scheme to develop with confidence that it is at least viable. 

spb can produce a concise study that encapsulates all the relevant issues to consider and offer a variety of potential solutions that can help to form the brief to move a project forward.

2. Design & Planning

The first idea is not always the right idea. The design development stage of a project is essential to get the best solution that fits within both site constraints and budget.

We have a proven track record in securing planning consent for a range of projects including change of use, listed building consent as well as utilising permitted development rights. 

3. Post Planning

Once the necessary permissions are gained, it is time to procure costs for the work. Depending on the scale of the project, different contractors will require a different level of information. 

spb can produce relevant drawings and specifications that suit the procurement route, whether it be a contractor already chosen or to be sent out to tender.
