Loft Conversion vs. Home Extension: Which Adds More Value in London?

In fast-moving areas like Camden, Mill Hill, and Totteridge, homeowners often face the same challenge: how to get more space without moving.

Two of the most popular solutions are loft conversions and home extensions. But which one gives you better value? Let’s break it down.

Loft Conversions – Smart Use of Existing Space

Loft conversions are one of the most cost-effective ways to expand your home. By transforming your unused attic, you can add valuable square footage without sacrificing outdoor space.

They’re ideal for:

• Extra bedrooms

• Home offices

• Ensuite bathrooms

Key Benefits:

• Often quicker to build than extensions

• Usually more affordable

• Typically fall under permitted development, making approvals easier and faster

Home Extensions – Full Custom Living

If you’re looking to expand your ground floor, extensions give you complete flexibility in design and layout. Rear and side-return extensions are especially popular in London.

They work well for:

• Open-plan kitchens

• Dining rooms

• Utility spaces or family zones

Key Benefits:

• Full control over the design

• More scope for creating modern, open-plan living

• Can dramatically change how you use your home

Which Option Adds More Value?

Both options boost property value — but in different ways.

• Loft conversions: Increase value by up to 15%

• Home extensions: Can add up to 25%, depending on area and finish
