Builders & Home Renovations in Mitcham
Building, Electrical and Plumbing Work in Mitcham
Golbik GBS works on homes throughout Mitcham and the CR4 postcode, from the historic Cricket Green and the edges of Mitcham Common to Figges Marsh, Pollards Hill and Colliers Wood.
Mitcham’s housing is largely Edwardian terraces and inter-war semi-detached and terraced houses, with fewer conservation restrictions than inner London. That makes it one of the areas where homeowners can often extend and convert under permitted development, adding space at a lower cost than in neighbouring boroughs.
We handle both complete building projects and smaller standalone jobs, such as rewiring, new consumer units, boilers and bathroom plumbing, with the same attention to detail.
Mitcham Homes and Neighbourhoods
Cricket Green and Mitcham Town Centre
Around Cricket Green, Mitcham’s oldest buildings sit within a conservation area, alongside Victorian and Edwardian houses. Refurbishments and sensitive rear extensions are typical, with external changes needing more care than elsewhere in CR4.
Figges Marsh and Streatham Road
The streets around Figges Marsh and towards Streatham are mostly Edwardian and inter-war terraces. Loft conversions, kitchen extensions and rewiring of older properties are frequent projects here.
Pollards Hill and Mitcham Common
Towards Pollards Hill and the borders of Mitcham Common, 1930s semi-detached houses are common. Their hipped roofs make them well suited to hip-to-gable loft conversions, and their gardens allow generous rear extensions.
Colliers Wood Borders (SW19)
On the Colliers Wood side, terraced houses and flats suit loft conversions, kitchen and bathroom renovations and full refurbishments.

Planning and Permitted Development in Mitcham
Mitcham is in the London Borough of Merton. Because much of the area is outside conservation areas, permitted development rights often apply to houses:
- Loft conversions – rear dormers and hip-to-gable conversions are usually permitted within 40 m³ of additional roof space for terraced houses and 50 m³ for semi-detached and detached houses, provided they do not face the street and meet the materials and height conditions.
- Rear extensions – up to 3 metres for attached houses and 4 metres for detached houses under standard rules, or up to 6 and 8 metres through prior approval with neighbour consultation.
- Lawful Development Certificate – confirms the work is permitted and is worth obtaining before building.
- Cricket Green and other conservation areas – permitted development is more limited, and roof alterations usually need planning permission.
- Flats and maisonettes – have no permitted development rights, so extensions need planning permission.
- Party walls – loft conversions on semi-detached and terraced houses normally require Party Wall notices to the neighbours.
Building Regulations approval is required in every case, and rules can change, so confirm the position for your address before work starts.
Frequently Asked Questions
Which parts of Mitcham do you cover?
We work across CR4, including Mitcham town centre, Cricket Green, Mitcham Common, Figges Marsh and Pollards Hill, as well as nearby Colliers Wood, Tooting, Streatham and Morden. We work within the M25 and up to an additional 10 miles beyond it.
Can I convert the loft of a 1930s semi-detached house without planning permission?
Often, yes. A hip-to-gable loft conversion with a rear dormer on a semi-detached house is usually permitted development if it stays within the 50 m³ volume allowance and meets the other conditions. Building Regulations approval is still required.
Do you carry out electrical and plumbing work on its own?
Yes. As well as larger building projects, we carry out rewiring, consumer unit replacements, lighting, heating and plumbing work as standalone jobs.
How big can a rear extension be in Mitcham?
Under standard permitted development, a single-storey rear extension can extend up to 3 metres on a semi-detached or terraced house and 4 metres on a detached house. Through the prior approval process, this can increase to 6 and 8 metres respectively, subject to neighbour consultation.
