Planning World

A faster, smarter, more affordable way to get planning permission anywhere in the UK.

Building Regulations ensure your project is structurally sound, energy‑efficient, fire‑safe, and compliant with national standards. Whether you’re building an extension, converting a loft, removing a load‑bearing wall, or constructing a new home, you need detailed technical drawings and calculations to satisfy Building Control.

Planning World prepares complete Building Regulations packages — drawings, structural calculations, SAP assessments, drainage layouts, and specifications — ready for submission and approval.

When you need Building Regulations

Building Regulations approval is required for:

Extensions (single or double storey)
Loft conversions and dormers
Garage conversions
Internal structural alterations (e.g., removing load‑bearing walls)
New build homes and annexes
Flat conversions
Basements and underpinning
Major thermal upgrades
Drainage changes or new connections

Even small projects often require Building Regulations approval if they affect structure, insulation, drainage, or fire safety.

Borough‑specific considerations

Building Regulations are national, but local authorities often scrutinise:

Fire safety in terraced and mid‑terrace properties
Thermal performance in conservation areas
Drainage capacity in London boroughs
Basement construction in Kensington & Chelsea
Acoustic separation in flat conversions
Structural integrity in older Victorian and Edwardian buildings

Your package is tailored to your building type, borough, and construction method.

Common mistakes to avoid

Projects often face delays or rejections when:

Drawings lack technical detail
Structural calculations are missing or incomplete
SAP Calculations are not provided
Fire safety measures are unclear
Drainage layouts are incorrect
Contractors work from planning drawings instead of technical drawings

Planning World eliminates these risks with a fully coordinated, compliant package.
