Why basement conversions work well in Hertford

Hertford blends historic period cottages and townhouses near the centre with generous Victorian villas and modern family homes on the edges, many with the plot space for extensions, garden rooms and full refurbishments. That makes Hertford a great place to convert a cellar or dig out a basement, and because we design and build in one team, your drawings are always buildable and your price is set early and honestly.

Planning and building control in Hertford

Hertford sits under East Herts Council. Converting an existing cellar is often permitted development, but lowering the floor or a full dig usually needs building control, and sometimes planning and party wall agreements, all of which we handle. As a design and build team we prepare the drawings and manage the whole process for you, so there is one team accountable from first sketch to sign-off.

What it costs, and how to get a figure

Converting an existing cellar here typically runs from around £1,500 to £2,500 per square metre, while a full dig-out with underpinning costs considerably more. Our online estimator gives you an itemised budget for your Hertford project in about a minute, emailed as a branded PDF, and we confirm a fixed price after a free, no-obligation site visit.
