Question 1

Do the large interwar semis in Winchmore Hill and Southgate suit two-storey extensions?

Accepted Answer

The substantial 1920s–1940s semis on the quieter residential streets in N14 and N21 often have the plot width to add a two-storey side extension, recovering the side-passage space on both floors simultaneously. This typically requires a planning application (not permitted development) but is generally well received by Enfield Council on these roads. TB&D Construction advises on planning prospects during the site visit.

Question 2

Are there areas in Enfield with conservation restrictions affecting works?

Accepted Answer

Enfield has several conservation areas including Enfield Town (EN1) and parts of Winchmore Hill (N21), where alterations to the front elevation, removal of original windows and additions visible from the street are restricted. Internal renovations and rear extensions typically remain unaffected. TB&D Construction checks the conservation area map for every Enfield property before quoting.

Question 3

How much does a boiler replacement cost in Enfield, and how long does it take?

Accepted Answer

A like-for-like combi boiler replacement in an Enfield house is typically completed in a single day on site and costs £2,200–£3,800 depending on the boiler specification and pipework complexity. First-time installations or system changes take 1–2 days. TB&D Construction coordinates the work through our Gas Safe registered partner, who issues the Building Regulations certificate and manufacturer warranty directly to you.

Question 4

What party-wall considerations apply to two-storey side extensions on Enfield's interwar semis?

Accepted Answer

Two-storey side extensions on the wide interwar semis in N14 and N21 involve building a new structural wall along the flank — which, if it is or is close to the shared boundary wall, triggers the Party Wall Act. The notice period for work that involves building on the party wall is two months; for excavation adjacent to the wall, one month. TB&D Construction reviews the boundary conditions and structural proposals on the site visit and prepares Party Wall Act notices as part of the planning and construction package.

Question 5

What range of project types does TB&D Construction deliver across Enfield's housing stock?

Accepted Answer

Enfield's housing is predominantly interwar — large hipped-roof semis in Winchmore Hill (N21), Southgate (N14) and Palmers Green (N13) — with Victorian terrace streets in Edmonton (N18) and newer estates further east. TB&D Construction carries out hip-to-gable and dormer loft conversions, two-storey side extensions, rear kitchen extensions, full house renovations and boiler installations via our Gas Safe registered partner across all Enfield postcodes. One named project manager handles each job from first survey to Building Regulations sign-off.
