Our Process

The Design to Budget Approach

The traditional design-to-build process can feel daunting. Many homeowners spend months shaping their dream home and securing planning permission, only to reach the build stage and face unexpected costs that don’t align with budget. And when it’s your dream home, no one wants to compromise.

That’s why we turned the traditional approach on its head with our Design to Budget Approach, available with our design and build service. Learn more about our unique process here.

About us

Get to know us

We’re known for bringing a fresh, sometimes quirky approach to reimagining period homes blending contemporary flair with a deep respect for original character. Our work strikes a careful balance between old and new: thoughtful, playful, and never afraid of statement colour or bold design details.

We don’t follow design trends for their own sake, instead, we approach each home on its own terms, creating spaces that feel naturally light and open, or calm and atmospheric, depending on what suits it best.

Customer Reviews

We’re trusted by clients to deliver beautiful results

We’ve helped these homeowners create bold, beautiful, functional homes through a transparent, design-first, and solution-driven approach.

The highest testimony I can give is having worked with Sean and Stephen in a professional capacity through my role at the London Borough of Waltham Forest I then chose them to be the architects for my own home extension. I trusted them to improve my home, meet my children, husband (and my cats) and to shape how I will live in my house for many years to come…. they are trustworthy, conscientious and sticklers for detail. I felt comfortable leaving them a key to my home when they needed to take measurements and felt able to ring them once the design was completed for advice on anything from the contract, to design challenges, changes and how to approach issues with the contractor.

A House with Lofty Ambitions

It’s been excellent working with Seán and Matt on the renovation of our house. They listened closely to what we needed and developed thoughtful and exciting designs that responded to our brief and budget. They also made some great suggestions for things we hadn’t even thought of, which has strengthened the design further. We’ve just submitted our planning application, and we can’t wait to see their designs turn into reality.

A House with a Sunlit Kitchen

I commissioned Pencil & Brick’s construction arm to carry out a two-storey rear extension on my property in East London between September and December 2022, for which I had already completed architectural and structural designs. Being my first construction project, I was hugely grateful for the insight and guidance that Pencil & Brick’s highly experienced and dedicated team provided throughout the project. The project was well planned and executed, and I received regular updates and feedback from developments on site. I always found Pencil & Brick to be totally honest and transparent, and this is something that the company clearly prides itself on. Pricing estimates were accurate and realistic, and costs at all stages of the project were clearly broken down and explained.

“Pencil and Brick were a pleasure to work with. They were clear and quick in communications. They helped us prioritise when compromise was required, and are honest and direct. We engaged them as architects, project managers, and builders to renovate our Victorian home. The complete service made a stressful process as painless as possible and meant the project was finished within expected budget and on time. They collaborated with us, listened to our requirements and tailored their approach to our needs, offering clever solutions to tricky areas…They have transformed an uncomfortable house into a home we look forward to returning to and waking up to.”
