Starting from Scratch
A modest detached house with a tired single-storey extension once occupied this plot in one of Hitchin’s quieter residential corners. The decision to demolish and start again gave the family — and us — a genuine opportunity: a home designed from scratch, around exactly how they wanted to live.
The brief called for five bedrooms, space for extended family and visitors, and a long-term home the clients wouldn’t need to leave. Sustainability was a priority from the outset. The finished house carries an EPC rating of 99 — exceptional for a property of this size — achieved through an integrated solar array, air source heat pump, and MVHR ventilation system.
The Design
The design evolved through several iterations before settling on the current form: a central gabled wing flanked by hipped roofs, red brick to the lower storey and cream render above, with dark aluminium-framed windows throughout. The full-height window to the master bedroom was a collaboration between architect and client — a deliberate centrepiece that brings the design together and makes an impression from the garden.
Inside, the clients led on the interior specification, with our input on layout and key details. The parquet flooring, steel-framed internal glazed doors supplied by RK Steel of Hitchin, and a considered cloakroom all reflect a family who knew what they wanted and had the space to realise it properly.
Planning & Delivery
Planning was straightforward, with modest amendments to address neighbouring amenity. Construction by E Coulson took just over a year, with the family renting locally during the build. We were involved from first conversation through to handover.
The Outcome
A five-bedroom family home in SG4 9, built to a high specification, with a near-perfect EPC rating. A house the family won’t need to leave and shouldn’t want to.
If you are considering a new build house — whether as a replacement for an existing building or on a fresh plot — we can help you develop the brief, navigate planning, and manage the delivery.
