Question 1

How much does a single-storey rear extension cost in Hemel Hempstead (HP2 or HP3)?

Accepted Answer

A single-storey rear extension on an HP2 or HP3 property typically comes in between £28,000 and £55,000, depending on footprint, roof style, glazing, and whether a Party Wall Award is required for a semi-detached house. The New Town estates in Adeyfield, Grovehill, and Bennetts End tend to have standard timber-framed rear walls that simplify the structural tie-in. PrimeCraft prepares a fully itemised written quote on the day of the site visit, with groundworks, structure, glazing, finishes, and drainage costed individually so nothing is buried in a lump sum.

Question 2

What planning restrictions apply to loft conversions in Hemel Hempstead's Old Town Conservation Area (HP1)?

Accepted Answer

Within the HP1 Old Town Conservation Area, dormer windows on principal or street-facing elevations almost always need planning consent rather than permitted development, and replacement materials must match the existing brickwork and roofing. Outside the Conservation Area — the majority of HP2 and HP3 — most hip-to-gable or rear dormer loft conversions qualify as permitted development as long as the volume addition stays within the prescribed limits. We check your specific address against Dacorum Borough Council's planning layers at the site visit before recommending the most appropriate route for approval.

Question 3

Can a kitchen refit and boiler replacement be run together on a Hemel Hempstead project?

Accepted Answer

Yes — a kitchen renovation and heating upgrade often share the same visit because the boiler and main pipework are usually accessed from within the kitchen. For any gas element — boiler swap, flue repositioning, radiator additions — PrimeCraft brings in our Gas Safe registered partner, whose certification covers all work to current regulations. PrimeCraft directly manages the units, worktops, tiling, electrics, and associated plastering across HP1, HP2, and HP3. The entire project is fully insured throughout, and a written workmanship guarantee is issued on completion.
