Construction Trends in Haringey
Muswell Hill and Crouch End sit at the more affluent end of the borough, with large Edwardian semis and detached houses that produce a consistent flow of loft conversion and extension work. The sweeping streets around Alexandra Palace were mostly built in a short burst around the turn of the twentieth century, and many of those properties are now overdue for significant updating. Hornsey and Stroud Green have Victorian terraces that attract buyers looking for character at a lower price point, and these streets generate regular applications for rear additions and loft schemes. Tottenham and Wood Green have a more mixed stock, including post-war housing and older terraces, where the projects tend to be more practical and less value-driven.

Below is a breakdown of the most common construction project types submitted to Haringey Council over the past 30 days.
In Haringey, Extensions account for the majority of planning applications (95 of 130 in the last 30 days), with Loft Conversions also showing consistent demand alongside Garden Rooms.

Demand for Building Work in Haringey
The north of the borough has seen sustained demand from families priced out of Camden and Islington who still want a house with outdoor space and good transport links. Once they are in, many carry out building work in the first few years of ownership, having bought at the top of their budget with plans to improve. Muswell Hill and Crouch End in particular attract buyers who treat the purchase as a long-term project. The regeneration activity around Tottenham Hale and the stadium area has also increased interest in the south of the borough, bringing through a different type of buyer and a different category of work.
