The Brief

Our clients, a recently retired couple, wanted to live differently in their home — a generous, light-filled, open-plan space that opened directly onto the garden, where they could cook, eat, and entertain in one connected room. Just as importantly, they wanted to leave the elegant proportions of the original Victorian reception rooms alone, so those could be redecorated and enjoyed in their proper traditional character. The new extension would do the modern living; the old house would do the rest.

Existing Conditions

The rear elevation we inherited was characterful but disjointed: the main two-storey Victorian volume in red brick, with a smaller single-storey wing tacked on to one side. The garden was lovely but the house turned its back on it through small openings and a tired side return, with no real connection between inside and out.

Design Response

Rather than build one big rectangular box across the back of the house, we broke the new accommodation into three linked pavilions, each marked externally by its own shallow-pitched gable. The three gables do a lot of quiet work. They keep the ridge line modest — important for daylight to the existing first-floor windows and for the conservation area setting. They give the extension a rhythm that reads as a series of subordinate outbuildings rather than a single bulky addition. And they allowed us to zone the interior naturally: kitchen and sitting area in the first pavilion, central dining space under the larger middle gable with its rooflight, and a further sitting room in the third.

Standing-seam zinc was chosen for its affinity with natural slate — from the street, the roof reads as a cool-grey continuation of the Victorian language — and for the crispness of its detailing. Solarlux bi-folds and fixed glazing bring the garden into all three spaces. Roof overhangs and specialist solar-control glass manage summer heat gain without the need for mechanical shading.

Conservation & Planning

The Conservation Officer requested a reduction in plan depth from the original proposals. The amendment was straightforward and, honestly, improved the proportions. The approved scheme is better for the conversation.

The Outcome

The extension added approximately 100 m² to the house and, more significantly, gave the clients the way of living they had been imagining. Old and new each get to do what they do best. The existing Victorian rooms are quieter and more themselves for having been left alone; the new extension is confident about being new.

If you are considering an extension to a period property in a conservation area — particularly in Hitchin or the surrounding area — we have specific experience of what the planning process requires and what good design within those constraints looks like.

Two-Storey Side Extension

Private client — two-storey side extension and internal alterations, led by Jon Read

Before the work, our home simply wasn’t working for the way our family lives. We were short on space, the layout didn’t flow, and we were forever juggling between rooms that never quite did what we needed — nowhere for the children to play, nowhere to entertain properly, and no way to have both sociable open space and somewhere quiet to retreat to.

Jon designed a two-storey side extension, with internal alterations, that solved all of this. He added two bedrooms, each with an en suite, a playroom for the children, and a large open-plan kitchen and dining area for entertaining — all while preserving a separate, private living room. The design struck exactly the right balance between sociable, open living and quieter private space. Now we can host with ease, the children have their own space to play, and we can still close a door and enjoy some peace when we want it.

What stood out most was how well Jon kept the project on track. He was attentive throughout and it was exceptionally well managed from start to finish. At no point did we pay more than had already been budgeted, so we were never exposed to unexpected costs. His recommendations for builders were excellent, and he was full of design ideas yet always genuinely open to our input — a rare combination of expertise and good listening.

A year on, the space is a joy to live in. It has transformed how our family lives day to day and feels as though it was always meant to be part of the house. We wouldn’t hesitate to recommend Jon and the Pentangle team to anyone considering an extension.

We worked with Jon and the team at Pentangle on the design and build of our new home in Hitchin, and the experience was excellent. They were consistently responsive, listened carefully to our requirements, and brought thoughtful, creative ideas to the project. The result is a home we absolutely love. We’re very happy to recommend Pentangle.

New House, Wymondley Road, Hitchin

Private client — new-build family home, led by Jon Read

We presented Jon with the daunting task of helping us realise our dream home without breaking the bank — starting with the question of whether to extend and remodel or start from scratch. He helped us work through that decision, took our brief, and came back quickly with strong workable designs. We iterated, as you do, but Jon turned things around promptly, was always happy to adapt, and gave us clear advice on planning and regulation throughout. By the time we got to build, the design felt tight, and that was invaluable.

From the tender process through to completion, the project was managed with real professionalism — rigorous on the detail, straightforward in communication, and steady when decisions needed to be made. Jon handled the contract administration and trades management expertly, and was always honest with us about how best to approach things rather than just telling us what we wanted to hear. When challenges came up, as they always do, they were met with pace and a focus on finding solutions.

The result: on time, on budget, and exactly what we’d hoped for. We lose count of the compliments we receive. More than that, we live in it every day and it works beautifully for our busy family life — the layout, the space, the characterful features, all of it. We wouldn’t hesitate to recommend Pentangle to anyone taking on a project of this scale.

Private client — rear extension and loft conversion, designed by Gareth Leech

As first-time house renovators, Gareth and the team at Pentangle Design couldn’t have made the process easier. We were incredibly impressed by the designs and options they presented, which completely surpassed the simple rear extension and loft conversion we had originally envisaged.

Gareth worked closely with our builder throughout the project and was a huge source of support in bringing the design to life. His involvement helped navigate any difficult discussions and kept the project moving forward smoothly.

We asked Gareth to create our forever home and, seven years later, that’s exactly what we still have. We couldn’t be happier with the result and couldn’t recommend Gareth and the team at Pentangle Design more highly.

“Pentangle: the perfect fit

We chose Pentangle to be our architects after appraising a number of other firms. We were impressed with photographs of a particular house, which looked very much like what we had in mind. Gareth Leech from Pentangle chimed with us from the first. He designed a fabulous house which we instantly loved. It had the touches of the arts and crafts movement we wanted. Gareth guided us through some challenges in the planning process, then he advised us on a number of builders he had worked with previously. He maintained a strong relationship throughout with the builder and gave us expert advice at every stage, so that we felt confident at the payment points. The build was completed in under 12 months, which felt like some kind of record, and we thank the day that we chose Pentangle. The house has had many complimentary comments from friends, neighbours and passers by and we love every aspect of it. We can highly recommend Pentangle. Thank you Gareth.”
