South London homeowners are increasingly choosing house extensions as a smart alternative to moving. With property prices rising across the capital, extending your existing home can deliver more space, improved functionality, and increased property value—without the stress of relocation.

At The Loft Conversions, we specialise in high-quality house extensions in South London, designed to complement your property and lifestyle. Whether you live in a Victorian terrace, a semi-detached family home, or a modern townhouse, there’s an extension solution to suit your needs.

Below, we explore all major types of house extensions available in South London and how they can transform your home.

Rear House Extensions – The Most Popular Choice

A rear extension is one of the most common house extensions in South London, particularly for terraced and semi-detached homes. By extending into the garden, you can dramatically increase your ground floor living space.

Rear extensions are ideal for:

  • Open-plan kitchen and dining areas
  • Kitchen extensions with skylights or bi-fold doors
  • Family living spaces that connect indoors with outdoors

This type of extension is perfect for homeowners wanting modern, light-filled interiors while maintaining the character of their home.

Side Return Extensions – Unlock Hidden Space

Side return extensions are especially popular in South London Victorian and Edwardian properties. Many homes have narrow, unused alleyways along the side—prime space for extension.

A side return extension allows you to:

  • Widen your kitchen or dining area
  • Improve natural light
  • Create a seamless open-plan layout

When combined with a rear extension, this becomes an L-shaped extension, one of the most valuable upgrades you can make to your property.

Single-Storey Extensions – Practical & Cost-Effective

A single-storey extension is a versatile solution suitable for kitchens, dining rooms, home offices, or playrooms. These extensions are often quicker to build and may fall under permitted development, reducing planning delays.

Benefits include:

  • Lower construction costs
  • Minimal disruption
  • Strong return on investment

Single-storey extensions are ideal for growing families and homeowners wanting functional space without major structural changes.

Double-Storey Extensions – Maximum Space, Maximum Value

For homeowners looking to significantly increase square footage, a double-storey extension is an excellent long-term investment. This option allows you to extend both ground and first floors.

Perfect for:

  • Adding bedrooms and bathrooms
  • Creating master suites
  • Increasing overall property value in South London

While planning permission is usually required, the end result can completely transform how your home functions.

Wrap-Around Extensions – The Ultimate Upgrade

A wrap-around extension combines a rear and side extension, delivering a dramatic transformation. This is one of the most impactful house extensions in South London, especially for period homes.

Wrap-around extensions offer:

  • Expansive open-plan living
  • Flexible layout options
  • A premium finish that attracts buyers

This option is ideal if you want a standout home tailored to modern living.

Over-Structure & Above-Garage Extensions

If outdoor space is limited, building above an existing structure—such as a garage—can be a smart alternative. These extensions work well in urban South London locations where maximising internal space is essential.
