Commercial-to-residential conversions
Converting a commercial building into residential space involves more structural complexity than it usually appears to from the outside. The existing frame, floor layouts and load paths were designed for a different use entirely – a warehouse, an office floor plate, a retail shell – and understanding what can be retained, what needs strengthening and what needs replacing is where the engineering work actually begins.
Getting that assessment right early determines how much of the existing structure can be reused, which has a direct bearing on programme, cost and the amount of waste the project generates. SCB Structures supports developers on commercial-to-residential conversions across London, Essex, Kent, Surrey and Hertfordshire, including complex and historic buildings where the construction methods and materials are often non-standard.

We start by assessing the existing structure to establish what it can support and where the constraints lie. From that, we advise on how much of the frame, floors and walls can be retained, what alterations are needed to accommodate the new layout, and where strengthening is required.
We design around historical construction methods where they’re present – older steel sections, jack arch floors, lime mortar masonry – and produce structural solutions that work with the building rather than against it. Load redistribution following wall removals or floorplan changes is a routine part of conversion work, and we manage that carefully to avoid consequences that only become apparent later in construction.
We’ve worked on a range of adaptive reuse schemes, including the transformation of historic and mid-century commercial buildings into apartments, HMOs and mixed-use residential developments.
Our approach
get in touchEvery conversion starts from a different place. The structural strategy on a 1960s concrete frame is completely different from that on a Victorian warehouse or a 1980s steel portal. We don’t apply a standard approach; we assess what’s there, establish what the new use requires, and find the most efficient route between the two.
Where possible, we design to maximise reuse of the existing structure. Retaining what’s already there reduces cost and programme time, and it avoids the embodied carbon that comes with demolishing and replacing structural elements that could have been kept. That preference for retention shapes how we approach the design from the outset, rather than being an afterthought.
