Romford and the surrounding RM postcode area is one of the most active markets for loft conversions in Essex.
The housing stock here — predominantly 1930s and post-war semi-detached properties — is well suited to rear dormer conversions, with good ridge heights and the roof geometry to make the most of the available space.
Fox Conversions have completed loft conversions across Romford, Harold Wood, Gidea Park, Emerson Park and the wider RM district.
Most homes in the Romford area have hipped or gable-end roofs with enough ridge height to convert without structural complications. The most common conversion type here is a rear dormer — it maximises usable floor area, keeps the front roofline unchanged for planning purposes, and adds a full-height bedroom with en-suite.
Hip-to-gable conversions are popular on end-of-terrace and semi-detached properties, particularly in Harold Wood and Emerson Park, where the hipped end wall limits the usable space a standard dormer can achieve on its own.
If you are unsure which type suits your property, we will advise at survey. Most Romford lofts fall under Permitted Development — no full planning permission required.
Typical loft conversion costs in the RM postcode area run from around £40,000 for a Velux-only conversion up to £65,000 or more for a full dormer with en-suite. The main variables are the type of conversion, the roof structure, and the level of finish.

We recently completed a rear dormer loft conversion in Harold Wood, transforming a three-bedroom semi-detached house into a four-bedroom home with a luxury en-suite master suite. The project involved adapting a timber truss roof to accommodate structural steels, building a full-width rear dormer, and relocating solar panels onto the new flat roof section.
The conversion achieved full Havering Building Control sign-off and was completed in six weeks from start to finish.
Romford falls within the London Borough of Havering. Most rear dormer and Velux conversions qualify as Permitted Development under Havering's guidelines, meaning no formal planning application is required. Hip-to-gable conversions on semi-detached properties also typically qualify under PD in this area.
We manage the full Building Control process through Havering Council, from initial submission through to final sign-off and your completion certificate.
We cover the full RM postcode district and surrounding areas, including Harold Wood, Gidea Park, Emerson Park, Hornchurch, Upminster, Rainham, Collier Row, and Rush Green. For East London enquiries including Barking, Dagenham and Ilford, see our Essex and East London coverage page.
All surveys are free, with no obligation. Chris will visit your property, assess the roof structure and head height, and give you an honest view of what is achievable before any commitment is made.
