RSJ Installation Camberwell SE5 | MK Refurbishment

MK Refurbishment London Ltd completed this RSJ Installation Camberwell as part of a structural alteration to a basement flat.

The objective of the project was to remove part of the existing structural division and create a more open-plan interior with improved light, circulation and connection between the principal living areas.

This RSJ Installation Camberwell project significantly enhanced the overall structural integrity and aesthetic appeal of the space.

Because the wall formed part of the structure of the building, this was not a straightforward demolition project. The loads previously supported by the masonry needed to be transferred safely through a new structural steel beam and into suitable supporting areas at each end.

Our team carried out the structural alteration, installed the single RSJ, prepared the beam bearings and coordinated the works with Building Control.

The structural installation was inspected during the project and subsequently signed off by Building Control.

Single RSJ Installation Camberwell SE5

This project involved a single structural steel beam installation as part of the RSJ Installation Camberwell process within a basement flat in Camberwell.

Using one RSJ may sound relatively straightforward, but even a single structural beam forms part of a complete load-transfer system.

The beam itself is only one component.

The installation also needs to consider:

  • the load carried by the original wall,

  • the span of the new opening,

  • beam specification,

  • temporary support,

  • existing masonry,

  • bearing areas,

  • structural levels,

  • access for the steel,

  • Building Control requirements.

The steel therefore needs to be treated as part of the building structure rather than simply as a piece of material placed above an opening.

Creating a More Open-Plan Basement Flat

The architectural objective was to create a more open relationship between the existing internal spaces.

Basement flats can sometimes feel more enclosed than upper-floor accommodation because natural daylight is limited by their position within the building.

Removing an unnecessary visual division can therefore make a significant difference to how the interior feels.

A wider opening can improve:

  • circulation,

  • sight lines,

  • movement of natural light,

  • furniture arrangements,

  • connection between living spaces.

For this Camberwell flat, the structural alteration allowed two previously more separated areas to work together as a more open-plan interior.

The RSJ provided the structural support required to make that new arrangement possible.

Why a Load-Bearing Wall Needs Structural Support

A load-bearing wall carries weight from other parts of the building.

Depending on the property, that can include loads from floors, walls or roof construction above.

If part of that wall is removed, the load does not disappear.

It needs to be redirected through a new structural element.

In residential renovation, structural steel beams are commonly used for this purpose.

Although the term RSJ is widely used by homeowners and builders, the exact type and size of steel required depends on the structural design for the individual property.

The beam needs to span the proposed opening while transferring the supported loads to suitable bearing points.

This is why structural wall removal should never be approached as ordinary demolition.

Structural Steel Installation

The new structural steel was installed across the proposed opening to replace the support previously provided by the removed masonry.

Accurate installation was essential.

The beam needed to correspond with both the structural requirements and the physical geometry of the existing basement flat.

Several practical factors also need to be considered when installing steel in an existing property:

  • beam length,

  • beam weight,

  • access into the building,

  • restricted working space,

  • existing ceilings,

  • surrounding walls,

  • temporary support,

  • final beam position.

Basement properties can make access particularly challenging because large structural components may need to be moved through restricted entrances and circulation areas.

Planning the installation sequence before the steel arrives on site therefore forms an important part of the work.

Temporary Support During the Structural Work

Before structural masonry can be removed, the building above needs appropriate temporary support.

Temporary works maintain stability while the original load-bearing arrangement is being changed and before the permanent beam takes over its structural role.

The precise arrangement depends on the existing building and project-specific structural requirements.

The sequence is important.

The supporting structure should not simply be demolished first and dealt with afterwards.

Instead, the temporary support, opening formation and permanent steel installation need to follow a controlled construction sequence.

This is one of the most important differences between professional structural alteration and ordinary wall demolition.

Controlled Formation of the Opening

Once the required preparation was complete, the structural opening could be formed.

Controlled demolition helps protect the remaining masonry and reduces unnecessary damage around the new opening.

Existing residential walls may also contain other services or finishes that need to be considered.

These can include:

  • electrical cables,

  • plumbing,

  • plaster,

  • adjoining ceilings,

  • flooring,

  • other retained finishes.

Removing only the masonry required for the designed opening also makes the subsequent steel installation and making-good work more efficient.

A carefully prepared opening gives the contractor better control over the beam bearings and final dimensions.

RSJ Bearing Preparation

The areas supporting the ends of the structural beam are a critical part of the installation.

A steel beam can carry substantial loads, but those loads ultimately need to be transferred into the supporting masonry beneath the ends of the beam.

The bearing arrangement therefore needs to correspond with the structural requirements.

For this project, the bearing areas were prepared using traditional wet-bedded masonry support techniques before the steel was positioned.

I would describe the work this way rather than using terms such as “advanced technology” or promising “absolute stability”.

The important technical point is that the beam bearings were deliberately prepared as part of the structural installation rather than simply placing the steel onto existing masonry.

Why RSJ Bearings Matter

Structural steel concentrates the supported loads towards its ends.

Those concentrated forces then pass into the building beneath.

Depending on the design and existing construction, an engineer may specify:

  • padstones,

  • strengthened masonry,

  • steel columns,

  • other structural supports.

The correct solution varies from property to property.

A beam installed in one Camberwell Victorian property cannot automatically be assumed to require exactly the same bearing arrangement as a similar-looking opening next door.

Wall construction, masonry condition, span and loads above can all be different.

For this reason, the structural details should follow the requirements for the individual project.

Building Control Approval

A particularly useful feature of this Camberwell case study is that the structural works were inspected and signed off by Building Control.

The current project page confirms that the installation passed the necessary inspections and received Building Control approval.

This is an important part of load-bearing structural work.

Removing or altering a load-bearing wall changes the structure of the property and needs to satisfy the relevant Building Regulations requirements.

Building Control provides an independent compliance process during the project.

For the homeowner, retaining the completion documentation is also important for the future records of the property.

Working to Structural Requirements

A builder should not determine the RSJ size simply by looking at the width of the proposed opening.

Structural steel specification depends on the loads being supported and how those loads are transferred through the building.

Project-specific structural information may define:

  • steel section,

  • beam length,

  • bearing requirements,

  • padstones,

  • connection details,

  • temporary works considerations.

The contractor’s role is then to translate that structural design into the physical installation.

This requires accurate setting-out, controlled demolition and careful coordination with the existing construction.

Structural Work in Basement Flats

Structural alterations in basement flats can present additional challenges compared with similar work on a conventional ground floor.

Access is often more restricted.

There may also be limitations on where steel can be moved, turned and lifted into its final position.

Existing walls may form part of a larger converted property, so alterations need to consider the building above rather than only the individual flat.

Practical planning is therefore especially important.

Before starting work, consideration needs to be given to:

  • access routes,

  • steel handling,

  • waste removal,

  • temporary support,

  • protection of communal or finished areas,

  • working space around the opening.

These logistical elements form an important part of safely delivering the structural design on site.

Structural Alterations in Camberwell Properties

Camberwell SE5 contains a varied range of Victorian and Edwardian houses, converted flats, mansion blocks and later residential properties.

Older buildings may contain traditional brick walls and timber floor structures that have also been altered during previous renovations.

The existing construction should therefore be assessed rather than making assumptions based solely on the age or appearance of the property.

Previous openings, chimney removals or earlier structural work may all influence a new alteration.

That is particularly relevant in converted flats where the original house may have been modified substantially over its lifetime.

RSJ Installation vs Wall Removal

Homeowners often think first about the wall they want removed.

From a structural point of view, the more important question is how the loads supported by that wall will be carried afterwards.

The project therefore consists of two connected operations:

Load-Bearing Wall Removal

The existing structural masonry is removed or altered to form the new opening.

RSJ Installation

Structural steel replaces the support previously provided by the wall and transfers the load towards the supporting structure.

Neither should be considered independently.

The new opening only works safely when the permanent support system performs the function previously provided by the masonry.

Making Open-Plan Living Possible

The RSJ itself is ultimately a means of achieving the client’s architectural objective.

In this basement flat, the steel allowed the internal space to be opened up without losing the necessary structural support.

This created a more flexible interior and improved the relationship between the rooms.

Structural alterations are frequently incorporated into:

  • kitchen renovations,

  • open-plan living projects,

  • extensions,

  • flat refurbishments,

  • whole-house renovations.

In each case, the visible design change relies on correctly executed structural work behind it.

Why Building Control Sign-Off Adds Value

Building Control approval is particularly valuable on structural projects because it demonstrates that the alteration has been through the appropriate compliance process.

For future property transactions, documentation relating to structural alterations may also be requested by solicitors, surveyors or buyers.

This makes proper approvals and record keeping an important part of the project rather than simply an administrative exercise during construction.

For this Camberwell basement flat, the successful inspection and sign-off provide a useful documented conclusion to the structural work.
