Flat Roof Extension

Flat Roof Extension

A flat roof extension is a modern, cost-effective way to increase ground-floor living space. It offers a sleek, contemporary appearance and is ideal for kitchens, dining rooms, home offices or utility rooms.

  • Generally more affordable than pitched roof alternatives
  • Minimal impact on existing building height
  • Perfect for modern, clean-lined architecture
  • Easier to maintain and adapt in the future

Side Extension

Side Extension

A side extension expands your home along the existing side wall, often using underutilised alley or passage space. A popular way to increase internal floor area without significantly reducing garden size, particularly for terraced and semi-detached properties.

  • Makes efficient use of wasted space
  • Improves layout, flow and functionality
  • Increases overall property value
  • Many single-storey designs fall under permitted development

L-Shape Extension

L-Shape Extension

An L-shape extension transforms unused side and rear space into a large, versatile living area, perfect for open-plan layouts, larger kitchens, utility rooms or extra bedrooms.

  • Creates generous, multi-functional floor space
  • Ideal for Victorian and Edwardian properties
  • Excellent natural light with multiple elevations
  • Allows for creative interior zoning

Double-Storey Extension

Double-Storey Extension

A double-storey extension is the most impactful way to maximise your property's footprint, adding substantial living space across two floors, often used for larger kitchens, extra bedrooms, bathrooms or a home office.

  • Delivers the greatest increase in square footage and value
  • Creates balanced living and sleeping arrangements
  • Ideal for growing families
  • Long-term, future-proof investment
