Ealing Project Update: Basement Structure and Extension Progress Taking Shape

Posted on ZXCZXC12 June 202612 June 2026 by FJDigital

We are pleased to share the latest progress from our substantial refurbishment and extension project in Ealing, where work continues on the transformation of a large Victorian property into a highly efficient, low-carbon family home. Designed by Beasley Dickson Architects with structural engineering by Foster Structures, this project combines extensive structural alterations with a high-end contemporary finish.

Project Overview

This ambitious scheme includes:

Complete strip out of the existing property
New roof structure and roof coverings
Large rear extension
Extensive alterations to the existing structure
New basement beneath the existing house
Ground source heat pump installation
Low-carbon, high-efficiency building upgrades
Complete luxury interior fit out

The project has been carefully designed to modernise the property whilst retaining the character of the original Victorian home.

Significant Structural Progress on Site

Recent weeks have seen major progress across several key areas of the build.

The new rear extension is now clearly visible, with the walls, structural steelwork and floor structures all coming together. The large open-plan rear elevation has been formed using substantial steel beams, creating the expansive internal living spaces that will define the completed home.

One of the most striking elements at this stage is the scale of the structural works. The combination of steel framing, load-bearing masonry and carefully coordinated temporary works has allowed us to create large openings whilst maintaining the integrity of both the existing building and the new extension.

The photographs also show the impressive brickwork detailing that will help seamlessly connect the new structure with the character of the original property.

Basement Construction Continues

Alongside the extension works, progress continues on the new basement construction beneath the existing house.

Creating a basement below an existing structure requires meticulous planning and engineering. The excavation and retaining works have now allowed the basement spaces to take shape, with structural walls, waterproofing systems and access points becoming increasingly visible.

The basement will provide valuable additional accommodation whilst maximising the available footprint of the property without impacting the surrounding site.

As the project progresses, further structural elements will be completed before attention turns towards internal layouts, services and finishes.

Looking Ahead

With the main structural framework continuing to progress, the scale and ambition of the project are becoming increasingly apparent.

Over the coming months, works will continue on the roof structure, external envelope and internal construction as we move closer towards the next phase of this exciting transformation.

We look forward to sharing further updates as this exceptional Ealing project continues to develop.

Major Progress on Our Ealing Refurbishment Project

Posted on ZXCZXC10 March 202610 March 2026 by FJDigital

Impressive structural alterations, a new basement and a complete rebuild of the roof are transforming this Ealing property.

Our team has been making strong progress on an extensive Ealing refurbishment project. This project has involved stripping the existing property back to its core before transforming it into a contemporary, luxury home.

Working alongside architects Beasley Dickson and structural engineers Foster Structures, the scheme combines structural alterations, a new basement and a full interior fit out to high-end specifications.

The result will be a stunning home designed for modern living.

A Full Structural Transformation

This project began with a full strip-out of the existing house. The team removed internal finishes and structural elements to prepare the property for significant alterations.

The scheme includes:

A new roof structure and slate coverings
A rear extension to increase internal space
Structural alterations throughout the existing building
A new basement beneath the property
A premium interior fit out

Together, this will transform the property both structurally and aesthetically.

Roofing and External Works Taking Shape

Recent progress on the roof has been particularly impressive. The new roof structure is now in place and the slate coverings are being installed.

The slate roof retains traditional character while providing long-lasting performance and durability. New dormer details and carefully finished rooflines are helping to add overall definition to the home.

As these external works continue, the architectural elements of the property will come together beautifully.

Basement Construction and First Fix

Beneath the existing structure, a new basement is being created to add valuable living space.

The first fix stage in the basement is now complete. This includes plumbing and electrical infrastructure that will support the future function of the space.

Once finished, the basement will integrate seamlessly with the rest of the house and provide additional living areas.

Designed for Efficiency and Low Carbon Living

This project is not just about creating space, but performance and sustainability.

The home will incorporate a ground source heat pump, helping to reduce operational energy use and carbon emissions. Combining modern insulation with high-efficiency systems, the property will deliver strong environmental performance.

These measures support the growing demand for low-carbon residential properties.

Looking Ahead

With the structural work well underway, the project is progressing toward the next phases of construction.

Over the coming months, the team will continue working on completing the extension, external envelope and internal build stages before moving onto the internal finishes.

We look forward to sharing further updates as this impressive Ealing refurbishment continues.

Ealing Residential Redevelopment – Project Progress Update

Posted on ZXCZXC22 January 202623 January 2026 by FJDigital

Basement and Roof Milestones Mark Major Progress on this Complex Ealing Redevelopment

Works are continuing at pace on our major residential redevelopment project in Ealing, with significant milestones now reached both above and below ground.

This carefully planned scheme involves the full strip-out of the existing house and the construction of a new basement beneath the original footprint. Additionally, we will complete a rear extension, extensive structural alterations and a complete high-end internal fit out. Alongside the architectural transformation, the project has been designed with a strong focus on low-carbon performance and long-term energy efficiency.

Basement Structure Nearing Completion

One of the most complex phases of the build is now approaching completion, with the new basement structure largely formed beneath the existing property. We have carried out extensive structural works to safely create the additional level, providing valuable new living space while maintaining the integrity of the original house above.

A standout feature at this stage is the bespoke staircase which now links the basement seamlessly to the rest of the home. Designed as both a functional and architectural element, the staircase integrates seamlessly into the structure and plays a key role in how the new spaces connect and flow once the project is complete.

New Roof Structure In Place

Above ground, the project has reached another major milestone with the new roof structure now installed. The framing is complete and clearly defines the updated form of the house, marking a visible step forward in the transformation of the property.

With the roof structure in place, the building is beginning to take its final shape, allowing the project to move confidently into the next stages of construction and internal works.

With the roof structure now established, the building envelope is beginning to close in, providing a clear platform for the next phases of the programme. This stage allows greater coordination of follow-on trades and supports the smooth transition into weatherproofing, services installation and internal fit out as the project continues to progress.

Sustainable Systems and High-End Finish

Sustainability is a core part of this redevelopment. The house will benefit from a ground source heat pump and a low-carbon, high-efficiency design approach throughout. This will support long-term energy performance without compromising on comfort or quality.

As the structural phases conclude, focus will continue to shift towards the high-end fit out, where detailing, materials and craftsmanship will define the finished home.

Collaborative Delivery

This project is being delivered in collaboration with Beasley Dickson Architects, whose considered design has guided the transformation of the property. Additionally, Foster Structures have supported the complex structural requirements of both the basement and superstructure works.

Restoring Tottenham’s Heritage: Grade II Listed Buildings Undergo Major Transformation

Posted on ZXCZXC4 July 20254 July 2025 by FJDigital

We’re proud to be delivering a significant heritage restoration project on Tottenham High Road, where we’re breathing new life into a trio of Grade II* listed buildings originally constructed in 1725.

Our team is carrying out a full renovation and refurbishment to restore the historic character of these buildings while bringing them up to modern standards.

Internally, we’ve lifted and reinstated original floorboards, upgraded fire barriers and services, and carefully restored historic lime plaster ceilings. Every step is being taken with sensitivity to the buildings’ heritage and original detailing.

Externally, we’ve formed a new basement using an underpin sequence and poured concrete slabs. This lower-ground space will support a new extension at ground floor level, which will eventually house a café and a gallery space, offering new life and purpose to these historic structures.

We’re currently awaiting the installation of bespoke architectural glazing and a zinc facade. Once these are in place, we’ll begin work on the ground floor extension, continuing the balance between restoration and modern design.

Watch a walkthrough of the site below:

This is a project that requires care, experience and collaboration at every stage and we’re excited to see it take shape. It’s already been a pleasure working alongside F3 Architects and Nathan Goss Conservation .

We’ll be posting regular updates as the build progresses and look forward to sharing more soon. To see what else we’ve been up to recently, please visit our projects page.
