Underpinning strengthens or extends a building’s foundations, and on Notting Hill’s period houses it is needed for several reasons: to form or lower a basement, to carry the extra load of a new floor or large opening, or to stabilise a structure that has moved. Whatever the cause, it is structural work that must be engineer-led.
We carry out sequential, mass-concrete underpinning — the foundation is extended in small bays, one at a time, so the structure is never left unsupported. Because Notting Hill is largely terraced and semi-detached, shared walls mean the Party Wall etc. Act 1996 almost always applies and neighbours are formally protected.
Every scheme is designed and detailed by a structural engineer, governed by a written method statement, monitored as it proceeds and signed off by Building Control. It sits in one contract with the wider works, so the underpinning, structure and finishes never fall between trades.
Underpinning is structural work — the reason for it, the sequence and the engineering all matter.
Underpinning supports new basements, lowered floors, added loads, or stabilises a structure that has moved.
Every scheme is designed and detailed by a structural engineer with a written method statement.
Foundations are extended in small, sequenced bays so the building is never undermined.
Shared walls mean neighbours are notified, surveyed and protected under the Party Wall etc. Act 1996.
From diagnosis and design to a stable, signed-off structure — under one team.
Establishing why underpinning is needed — basement, loads or movement — before designing.
Engineer-designed underpinning sized to the ground conditions and loads.
A written, sequenced method statement governing how each bay is formed.
Notices, schedules of condition and awards with adjoining owners.
Controlled bay excavation, reinforcement and mass-concrete casting.
Movement monitoring of the building and neighbours during the works.

We carry out engineer-designed underpinning across Notting Hill’s period terraces and villas in W11, with full protection for neighbouring owners.
Notting Hill sits within the Royal Borough of Kensington & Chelsea — see our Notting Hill area page and South West London refurbishment overview.
