New-Build House with Basement Development – St. Albans, Hertfordshire
This St. Albans new-build home has been designed with a modern basement development, providing valuable additional living space while ensuring structural integrity, waterproofing, and compliance with Building Regulations.
A basement extension is a fantastic way to maximise space without expanding the footprint of a property, offering flexibility for home offices, entertainment rooms, or extra bedrooms. To ensure stability and safety, PorthouseDean provided expert foundation calculations, ensuring the structural framework, load-bearing reinforcements, and retaining wall designs were built to last.
Maximising Space & Functionality with Smart Structural Design
This project included:
✅ A basement development – Creating additional space below ground level
✅ Foundation calculations & structural reinforcements – Ensuring long-term stability
✅ Waterproofing considerations – Designed to prevent moisture ingress
✅ Integration with the new-build structure – Seamlessly connecting with upper floors
What we did
Our contributions included:
✔ Structural calculations for the basement & foundations – Ensuring safety and compliance
✔ Load-bearing wall assessments – Supporting both basement and above-ground structures
✔ Retaining wall design – Providing lateral stability for the basement construction
✔ Floor slab & foundation analysis – Strengthening the base for durability
With expert structural engineering, this St. Albans home now benefits from a spacious, highly functional basement extension, ideal for modern family living and future-proofed property investment.
