A Plot with History

The plot on Benslow Lane sits above an old chalk quarry face, immediately adjacent to the railway and a short walk from Hitchin station. The existing building — a bungalow — offered little worth keeping. More significantly, the site presented real engineering challenges: chalk voids beneath the surface, swallow hole risk, and a Japanese knotweed infestation on the cliff face. This was not a straightforward plot.

A private family with young children appointed Pentangle Design to design a replacement house. The brief was practical: four bedrooms, a study off the master bedroom, a south-facing garden screened from the road, and a home that would serve a growing family for the long term.

Engineering First

The foundation solution was a reinforced concrete raft — the appropriate response to the chalk geology and the uncertain ground conditions beneath. Japanese knotweed treatment on the cliff face was managed as part of the site preparation. Both were accounted for in the cost plan from the outset, which is worth noting: clients commissioning new build on plots with geological or ecological complications often find that these items emerge late in the process and feel like surprises. They should not be.

The Design

The house is south-facing, with the garden shielded from the lane. The layout gives the site’s particular geometry something to push against — the garden is a private world that you only understand from inside. A study sits off the master bedroom, a feature the clients identified early as important and which we carried through the design without losing to value engineering.

Sustainability was a priority from the brief stage. A high insulation specification, a dual-boiler heating system, and solar panels installed post-completion give the house good environmental credentials. The planning approval was secured through NHDC and the project was built out over the following years.

The Outcome

A difficult plot that a less experienced practice might have approached cautiously became a well-resolved family home. The cliff face, the geology, the railway — all managed. The design is quiet rather than showy, but it does what the family needed and does it properly.

If you have a plot with complications — ground conditions, topography, adjacencies, or ecological constraints — we can give you an honest assessment before you commit to anything, and carry the project through if you decide to proceed.

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.

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

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.”
