Sigma Architects
/Who we are

We are an architectural practice of long time collaborators. Lee Smith & Steve Basran after many years of working in a leading professional practice. A young but experienced studio.

Since being founded in 2021, we have delivered design-led, client-focused architectural solutions for a whole range of clients. From one-off private residencies to commercial developments. Masterplans to urban regenerations.

It’s not the size of a project that inspires us, but the opportunity to create something special.

/About Us

Sigma Architects Limited is a RIBA Chartered Practice situated in Derby. We are dedicated to providing exceptional consultancy services, combining professionalism with a friendly approach to meet the unique needs of our clients.

We combine creativity with practicality, ensuring that every project is beautifully designed, sustainable, and buildable within budget. Our hands-on approach, technical expertise, and strong commercial awareness set us apart. We also work closely with clients, offering a highly personal and tailored service from concept to completion.

/Our Process

At Sigma Architects we are committed to designing contemporary buildings that go beyond expectations without exceeding budgets. Our passion for design focuses on maximising the potential of existing elements - the site’s characteristics, the local climate, natural views, and the movement of the sun. We blend these with thoughtfully selected, materials, applied in modern ways that age gracefully, creating a sense of timelessness.

/Client Testimonials

Sigma Architects has been our trusted architectural partner for several years. Their sound, practical advice has been instrumental in helping us maximise value to ensure our projects deliver real impact for Portland College. Their ability to explore creative design solutions, maximise space, and provide cost-conscious recommendations has allowed us to achieve more than we initially thought possible. Their expertise has been invaluable in balancing practicality with ambition, ensuring we get the best possible outcome without compromising on quality. The team’s professionalism, responsiveness, and clear communication have made the process seamless, and we are grateful for their ongoing support.

On more complex projects the Sigma team have also shown their ability to bring different construction disciplines and contractors together to work as a team.

Edward Johnstone, Deputy Chief Executive Officer, Portland College

The team at Sigma Architects have been exceptionally helpful in providing us with the essential guidance we have needed to make an informed decision regarding many aspects of our renovation project to provide new offices for our Safe and Sound team alongside a community space for young people. We very much rely on the quality of advice we get from our professional advisors and Sigma have taken time to attend meetings, explain options and help us explore different designs and consider the relevant aspects of planning and cost. It would be true to say that we would have really struggled to make this work without their involvement. A very big thank you to everyone at Sigma Architects who have been involved.”

Mark Greasley, Projects Director, Wellglade Group / Trent Barton

They were proactive in their approach whilst unfailingly helpful and responsive to our needs. We are very beyond happy with the results.

Jamie is a visionary, who combines creativity with an extensive knowledge of planning; something that is increasingly important for an organisation new to this arena.

/Who We Work With
/Social Values

At Sigma Architects, we design with people in mind. Our work is shaped by social value by creating places that are inclusive, collaborative, and rooted in community.

/FAQs

Not always – but the real question is, do you want to make the most of your investment?

An Architect does much more than produce drawings. We bring expertise in design, functionality, aesthetics, sustainability, and regulatory compliance, ensuring your space works beautifully for your needs while meeting planning and building regulations.

Our role is to think beyond the obvious; considering natural light, energy efficiency, material choices, and long-term value. With our experience, we can help you unlock creative solutions, optimise space, and avoid costly mistakes.

While hiring an Architect is an additional cost, it’s a small fraction of your overall project budget – and one that often pays for itself through smarter use of space, improved efficiency, and added value. As registered professionals with ARB and RIBA, we guide you from concept to completion, making the process smoother, more inspiring, and ultimately more rewarding.

Architectural fees can vary depending on the location, complexity of the project, and the level of service you need. Some architects charge a percentage of the total project cost, while others offer fixed prices or hourly rates.

Our approach is flexible. After discussing your goals and possibly visiting the site, we’ll provide a tailored fee proposal – designed specifically for your project. This allows you to decide how much involvement and value you want us to bring to your project.

Our fees are usually broken down according to the RIBA work stages, from early design concepts to overseeing construction on-site. This gives you the option to engage us for all or just part of the process. As a general guide, our fees often range between 3% and 12% of the total construction cost, depending on the scope of work.

While hiring an architect might seem like a significant expense, it’s an investment in quality, creativity, and expertise. We’re here to ensure your project is thoughtfully designed, functional, and adds lasting value to your property. Get in touch, and we’d be happy to discuss your project and provide a tailored quote.

Before considering a lower quote, it’s important to evaluate what’s included in the other designer’s offer. We’re happy to review any competing proposals to see if we can adjust our services or scope to better fit your budget.

Each Architect brings their own approach, offering a unique experience and set of solutions. We encourage you to choose your designer based on who you feel understands your vision, works well with you, and can guide you through the entire project.

Our focus is on delivering professional service with a personal touch. We aim to fully understand your goals and deliver results that not only meet but surpass your expectations.

Yes! In addition to architectural design, we offer interior design and space planning services, ensuring that every element of your space both inside and out works harmoniously to meet your needs and aesthetic preferences.

Absolutely! Sustainability is at the heart of our designs. We incorporate energy efficient materials, passive design principles, and renewable technologies to create buildings that are environmentally responsible and cost effective to run.

We specialise in designing schemes that meet the requirements of planning departments, no matter where a project is located.

We have found that the appointment of a planning consultant on more challenging sites can improve your chance of success. Planning consultants understand planning policies in great detail and therefore good at communicating with planners on the same level – so can really help argue your case if need be. We have trusted relationships with several planning consultants and are happy to recommend one if we believe it would benefit your project.

We work on a wide range of projects, from one-off bespoke homes and house extensions to major commercial developments. No project is too big or too small, our focus is always on delivering the best possible design solution for your needs.

Yes! We have extensive experience working with developers, commercial clients, and businesses on everything from office spaces and mixed-use developments to large-scale housing schemes. Our commercial expertise ensures that projects are financially viable, market-driven, and efficiently delivered.

Simply get in touch! We offer an initial consultation where we can discuss your ideas, answer your questions, and outline the next steps. Whether you’re at the early concept stage or ready to move forward, we’d love to hear about your project.
