Heath

This high-spec new-build in North-West London included a full-footprint basement and underground swimming pool: a bold, complex project with a substantial structural package.

Before locking in the final design, the homeowners asked Re-Structured to take a second look. Their aim: reduce construction costs and carbon, without compromising on ambition.

We reviewed the structure in full, from the basement up, using advanced finite element modelling to test material performance and simplify where possible.

Key improvements included:

• Lighter steel beams (1,000kg+ saved on a single 10m span)
• Reduced concrete thickness in the basement walls and slab 
• Slimmer ground floor slab — creating more headroom and saving material
• Simplified construction types — improving sequencing and reducing risk
• Smaller pad foundations — cutting unnecessary bulk
   

We also reinterpreted the site’s water table to current standards, reducing uplift assumptions and enabling a leaner design.

• 8.2 tonnes of steel saved 
• 60 tonnes of concrete cut
• £55,000+ in construction cost savings
• 32 tonnes CO₂e saved — equivalent to 55 trees growing for 25 years
• Simplified programme and sequencing
• Zero compromise on architectural intent
   

All changes were delivered with minimal input from the architect, enabling a swift 3-week redesign and a smoother build ahead.

These reductions and savings are made possible to Re-Structured clients as we use carefully selected computer software to analyse structured. Below is an example of the ground basement slab, this heatmap shows how stressed the concrete was in the original design compared to the design created by us.

As you can see the light blue colour shows low stress or over specified concrete design, whereas the Re-Structured design highlights in dark blue where reductions in thickness can be made all whilst ensuring the slab is still safe. This reduction led to over 30 tonnes saved in concrete.
