LENIO is led by Sadadcharam Easwaran. He is a Chartered Civil Engineer and Member of the Institution of Civil Engineers (ICE). He is also a Chartered Building Engineer and Member of the Chartered Association of Building Engineers (CABE).
He has extensive experience working as a Party Wall Surveyor across London. In that time, he has managed all types of party wall matters. These range from straightforward notices on rear extensions to complex Party Wall Awards on basement excavations and structural works in dense urban areas.
In practice, when you contact LENIO, you speak directly with him. Not a call handler. Not a junior member of staff. The chartered Party Wall Surveyor who manages your matter from start to finish.
One surveyor. Your project. Start to finish.
In practice, ICE and CABE are not titles you are simply given. They are memberships that require proven competence, ongoing training and following a code of conduct. Here is what they mean for your project.
In short, a Chartered Civil Engineer understands how structures behave. Load spread, ground movement, foundation behaviour, the effect of excavation on neighbouring structures. For party wall matters involving basement digs, deep foundations or structural works on shared walls, this technical knowledge shapes every assessment. As a result, it informs every document Sadadcharam produces.
Also, a Chartered Building Engineer understands how buildings are built and how works affect existing fabric. For party wall matters, this means a precise knowledge of how proposed works interact with a neighbouring property. In turn, it informs the Schedule of Condition, the Party Wall Award, and every decision made during the process.
Together, these credentials mean you are working with an experienced party wall surveyor who understands the structural and construction impact, not just the paperwork behind them.

One of the most misunderstood aspects of the Party Wall process is the role of the Party Wall Surveyor.
Many people assume that a surveyor acts solely for the person who appoints them. However, under the Party Wall etc. Act 1996, a Party Wall Surveyor has a statutory duty to act impartially and fairly when carrying out their responsibilities.
Whether appointed by a Building Owner or an Adjoining Owner, a surveyor must make decisions based on the requirements of the Act and the facts of the case. Their responsibility is to ensure that the Party Wall process is administered correctly, that the rights of all parties are respected, and that any Party Wall Award is fair and legally sound.
At LENIO Party Wall Surveyors, this principle is central to everything we do. We believe that professionalism, integrity, and independence are essential to maintaining trust throughout the Party Wall process.
Led by Chartered Engineer and Party Wall Surveyor Sadadcharam Easwaran, LENIO provides balanced, practical advice that protects the interests of both Building Owners and Adjoining Owners while helping projects proceed efficiently and in accordance with the Party Wall etc. Act 1996.
