Conversions in Stevenage
Conversions across Stevenage and Old Town, Bedwell, Pin Green — 26+ years building in Hertfordshire.
Conversions in Stevenage
For conversions work in Stevenage and the surrounding Hertfordshire streets, what tends to matter most is matching the existing property — and that starts with knowing the local stock.
Stevenage combines a designated New Town built from the late 1940s with a much older High Street in the Old Town — two very different building stocks needing very different approaches.
Stevenage conversions for us are commonly integral garage and loft conversions across the New Town stock — straightforward shells, with proper upgrades to the original 1950s–1970s details.
Typical Stevenage use cases
- Annex conversions for multi-generational households
- Hip-to-gable conversions on end-of-terrace property
- Cellar tanking and conversion on older period property
- Garage conversions to home offices for remote workers
Local considerations for conversions in Stevenage
Stevenage New Town districts like Bedwell, Pin Green, Chells and Symonds Green are predominantly 1950s–1970s; the Old Town and surrounding areas have substantial Georgian, Victorian and inter-war stock. Chalky boulder clay dominates Stevenage's geology, but extensive 20th-century earthworks across the New Town mean made-ground is common — we always test before structural work.
- Upgrading original slabs and DPM on New Town garage conversions to current Building Regs
- Replacing or strengthening 1960s trussed lofts that can't safely take a habitable conversion
- Brick infill detailing on the front elevation that doesn't betray the conversion from the street
Stevenage Borough Council protect the Old Town High Street Conservation Area carefully, and several New Town estates carry restrictive covenants on front elevations.

Common conversions questions in Stevenage
- Can you convert an outbuilding into a home office in Stevenage?
- Yes — we routinely convert outbuildings and detached garages across Stevenage into fully insulated, electrically wired home offices and gyms.
