TCM Building in North London:
Local Knowledge, Expert Results
North London is one of TCM Building's most active service areas. We cover a broad sweep of North and North-East London — from Barnet and Enfield in the north to Haringey, Waltham Forest, and Hackney in the south. Our team has completed hundreds of projects across North London's diverse housing stock, from Victorian terraces and Edwardian semis to 1930s suburban semis and modern apartment conversions.
North London's Victorian and Edwardian terraced houses are among the most extension-friendly properties in Greater London — but they come with specific challenges that catch a lot of homeowners out. The rear gardens are typically long but narrow, which means the extension footprint needs to be designed carefully to preserve usable outdoor space. The party wall situation is almost always active: on a mid-terrace, you have two affected neighbours; on an end-of-terrace, you have one. And in many North London boroughs — particularly Haringey, Barnet, and Hackney — Conservation Area restrictions mean that works which would be Permitted Development elsewhere require a full planning application here.
We've worked across all the major North London planning authorities: Barnet, Enfield, Haringey, Waltham Forest, and Hackney. Each borough has its own character area guidance, and the quality of the planning officer relationship matters. We know which types of application sail through and which ones need careful pre-application engagement. That knowledge is part of what we bring to every North London project.

Why Local Knowledge
Matters for Building Work
North London spans multiple London Borough planning authorities, each with its own policies and character area guidance. TCM has experience working with all the major North London authorities and a strong track record of securing planning approvals. We advise on the planning position for every project during the free site survey.
North London's housing stock is predominantly Victorian and Edwardian — terraced houses, semi-detached properties, and purpose-built mansion blocks. This stock is exceptionally well-suited to loft conversions, rear extensions, and basement conversions. Many properties have existing cellars that can be converted into habitable rooms with relatively modest investment.
North London has a large number of Conservation Areas — particularly in Barnet, Haringey, and Hackney — which restrict external alterations and require planning permission for works that would otherwise be Permitted Development. Article 4 Directions are also common in parts of North London. TCM is experienced in navigating these restrictions and advising on the best approach for each property.
