Additionally the practice deals with surveying of building structure defects and the specification of remedial works. The practice is based in central London, however projects have been carried out in other parts of the country, notably Manchester, Leicester and Bristol as well as a few in France.

our client base

Ian Drummond Consulting Engineers is committed to providing a high level of expertise in professional engineering services.

We have deliberately remained small throughout the construction boom years to maintain a high level of quality control and personal service to our clients.

Our clients are property based commercial companies as well as private owner-occupiers in residential properties. Virtually all work stems from word-of-mouth referrals or repeat business.

Refurbishment and structural alteration

A large part of our work involves extension and refurbishment of existing properties, both commercial and residential. A notable example is the re-development of a twenty acre estate in East Sussex. Historic buildings have been altered and refurbished for the creation of 15 luxury retirement apartments with detached glass lift and stair core so as not to detract from the historic stonework. See Gallery pages 2,6,7 & 9.

Reports and Defects

As a result of the hot dry summers of the late 1980s IDCE became well versed in subsidence-related structural issues as shrinkable London clays affected large numbers of low-rise buildings. This provided the practice with a high level of expertise in recognising, reporting on and dealing with foundation problems in the traditional loadbearing brick buildings that form so much of London's housing stock.



During the property sector boom throughout the 1990s the practice became involved with larger commercial developments, notably along the south bank of the River Thames near London Bridge. Here an historic wharf building was completely refurbished which involved difficult foundation enhancement works, not only to arrest historic river wall movement, but also to facilitate an additional storey at roof level. The adjacent riverside site was subsequently re-developed as a new-build seven storey luxury apartment block. This required overcoming major hurdles in reducing the width of the river wall below high tide level, from two metres wide to 0.3 metres wide, in order to accommodate the requisite number of parking spaces in the basement. See Gallery page 9.

Work on the re-development of the Greenwich Promenade in conjunction with Conran & Partners was completed in time for the 2012 Olympic Games. See Gallery pages 4 & 5.


basement creation

When planning permissions for development above ground became more onerous and adding square footage below ground became more economically viable, an increased number of subterranean developments were undertaken. This involves both large scale underpinning and contiguous piling. In some cases the original house is temporarily supported in stages while the basement is excavated below. See Gallery page 3.

New build

Over the years a significant number of large, prestigious, single occupancy residences have been undertaken where the original building has been completely demolished, a full size basement installed and the building reconstructed above in an enhanced format.
