A Conservation-Led Approach – A message from Sam

Starting a project in a heritage or listed building, can feel overwhelming. There’s excitement, but also uncertainty:
– What’s possible?
– What will planning allow?
– How do I avoid making the wrong decisions?

At E2, we begin with clarity.

We take the time to understand your building, your lifestyle or commercial goals, and what really matters to you. We look closely at what’s significant about the property – what must be protected – and where there is genuine opportunity for change.

Many clients come to us after refusals, stalled projects, or conflicting advice. With the right conservation-led approach, those challenges often become the turning point – the moment a project finally starts to move forward.

My role is simple: to reveal possibilities you may not have considered, give you complete confidence in the decisions you make and help you avoid costly mistakes. Because when contemporary ideas are rooted in heritage logic, that’s where we find the ‘wow’.

 Trustindex verifies that the original source of the review is Google. Outstanding experience from beginning to end, and in fact beyond. E2 worked with us on an incredible barn conversion in Sussex. The attention to detail, care and effort they put into the project was just fantastic. Communication was top notch and we always felt in good hands. Professional, reliable and by far and away the best architects we found after a very extensive search. If you're considering a project on any scale, look no further!

 Trustindex verifies that the original source of the review is Google. E2 Architecture drew up and submitted a planning application for listed building consent and planning permission on a commercial to residential conversion in Sevenoaks with a prompt and positive result achieved. I found E2 to be very professional and astute in weighing up the various goals and interests of the project and balancing these in a sympathetic way with all conservation considerations in accomplishing an inciteful, creative and light touch design solution. I highly recommend their expertise.

 Trustindex verifies that the original source of the review is Google. E2 Architecture and Interiors were responsible for all stages of our project - a kitchen extension and interior redesign - from producing the inital design ideas, through detailed design and planning, tender, and on to on to managing and delivering the project .  Sam and Jim had great ideas, listened to what we wanted and were always available when we had questions. They worked brilliantly with the builder, and delivered a great looking, highly functional building (with a lot less stress than we were expecting having heard some other people's experiences of building projects).  We are very pleased with the process and delighted with the outcome.  It has really transformed our home.

Our Story: Why We’re Called E2

Most people assume E2 Architecture was named after the postcode where director and founder Sam first set up shop at his kitchen table.
But the real reason is something else entirely!
The name came from Sam’s guiding principle – bringing environmental and ecological thinking into everyday architecture.

– E for Environment
– E for Ecology

It’s why we specialise in contemporary conservation – preserving the past while designing for the future, in the context of our finite environment and ecological resources.
This philosophy became the foundation of everything we do.
