75 London Wall – Strip Out, Alterations, Builders’ Works, Asbestos Removal, Temporary Works, Decommissioning

KpH was appointed to deliver full internal strip out and enabling works at 75 London Wall – the first stage of a major redevelopment that expanded the building’s footprint by 40% and added five new floors. With 89% of the original structure retained, the project called for a low-carbon, high-precision approach. Working across a live, multi-storey environment, our focus was on safe delivery, smart logistics, and pushing circular economy principles from day one.

We carried out the full internal strip out across nine floors, from Basement 3 up to Level 8 – removing all redundant M&E, floor and ceiling finishes, partitions, wall linings, kitchenettes, and 17 lifts.

In the basement we dismantled extensive plant and services using hot works, supported by a gantry and hoist system that kept materials flowing with up to 20 waste movements a day.

We also managed the scaffold installation around the full building wrap, supported archaeological investigations, installed temporary shoring, and maintained safe access for MOLA teams.

Throughout the works we led the project’s reuse strategy – redistributing over 700 tonnes of materials for use on other sites and contributing significantly to the project’s embodied carbon savings.

• Delivering a project of this scale within a 24-week programme meant every day had to count. Waste logistics, team coordination, and scaffold movements all had to align precisely to maintain momentum.
• The inclusion of the external façade scaffold package – procured directly by the client with GKR Scaffolding post-contract award – was successfully integrated. This allowed the follow-on demolition contractor, Erith Group, to gain a valuable head start ahead of the demolition phase in January 2025.
• As the strip out progressed, some reuse plans had to evolve – most notably when marble originally intended for retention was deemed unsuitable, prompting a pivot to off-site redistribution.
• With design development happening in real time, we worked closely with survey teams to feed live data into decision-making, helping the redevelopment progress with fewer surprises down the line.
• Operating across three basement levels with restricted access added another layer of complexity. Plant removal, scaffold sequencing, and material movements were meticulously planned – often down to the hour.

A solid waste and logistics plan was crucial – the gantry and hoist setup kept the job moving and helped us stay on schedule.

When reuse plans needed to change, quick thinking and strong supplier relationships helped us stick to the project’s sustainability goals.

Early collaboration and time allocated within the prestart programme, alongside the design and survey teams made a real difference,  we could solve problems on the ground instead of fixing them later.

Most importantly, this project proved that circular economy delivery can work at scale. Over 700 tonnes of material reused, 900 tonnes of embodied carbon saved and not a single delay because of it.

This is the second project we have used KpH on a highly complex cut & carve project in London and they have been a joy to work with on both occasions. Their team have always been collaborative in the way that they interact with our design team and there is a no nonsense and honest approach to the way in which they work and report on key issues & progress. Ultimately we want to work with people who can make a difficult project an enjoyable one, but alongside that they maintained delivery on a tight programme, pushed the re-use agenda more than we were expecting and went over and above for the wider benefit of the project.
