Construction Trends in Southwark
Southwark stretches from the Thames south through some very different neighbourhoods. Peckham, Nunhead, and Camberwell are dense with Victorian terraces on narrow plots, and these streets produce a consistent flow of planning applications for loft conversions and rear additions. Dulwich is a different story entirely: large detached and semi-detached Victorian and Edwardian houses, some conservation areas, and owners who tend to invest heavily in their properties. Bermondsey and Rotherhithe, closer to the river, have seen significant regeneration and a mix of converted warehouse flats, older terraces, and newer builds that produce a more varied range of applications.
Project Type Breakdown
Below is a breakdown of the most common construction project types submitted to Southwark Council over the past 30 days.
In Southwark, Extensions account for the majority of planning applications (111 of 202 in the last 30 days), with Loft Conversions also showing consistent demand alongside Heritages.

Domestic vs Commercial Projects in Southwark
In Southwark, 69% of planning applications are domestic and 31% are commercial. Both segments offer opportunities depending on the scale of work you take on.
Demand for Building Work in Southwark
Southwark sits close to the City and London Bridge, and that proximity has pushed property values up across much of the borough over the past decade. Buyers in Peckham and Nunhead in particular have arrived expecting to do work, and many plan extensions or loft schemes within the first couple of years of owning. In Dulwich, where properties are larger and values higher, owners are more likely to undertake substantial refurbishments rather than single-room additions. Across the borough, the cost of moving on is steep enough that most people choose to improve what they have.
