Garage conversions for flexible, everyday space

A garage conversion is a smart way to gain a home office, playroom, guest room or utility space—often with a quicker programme than a full extension.

We focus on insulation, heating, ventilation and natural light so the new room feels like part of the home rather than a cold afterthought.

Where the garage adjoins a boundary, party wall considerations can apply. We can support the conversation through our party wall support guidance. If you are exploring your options, you can request a fixed-price quotation or browse recent work in our projects gallery.

What we check before you commit

Every garage is different. These checks help avoid surprises.

  • Existing structure and foundations – suitability for conversion.
  • Floor levels and damp-proofing strategy.
  • Insulation upgrades to walls, roof and openings.
  • Relocating services and improving lighting and ventilation.
  • Approval route: Building Regulations and any planning constraints.

How we deliver a high-quality conversion

We survey the space, confirm design options and agree a specification. Then we manage the work: openings, insulation, plastering, electrics, plumbing (if needed) and finishes.

If you want the conversion to connect better to the rest of the house, we can also reconfigure internal walls as part of a wider refurbishment.

We work across East Molesey, West Molesey, Hampton Court, Kingston upon Thames, Esher, Surbiton, Elmbridge and surrounding Surrey & South West London.

Benefits of converting your garage

  • Fast route to extra space with minimal external change.
  • Ideal for home offices, studios and guest rooms.
  • Improves comfort by upgrading insulation and glazing.
  • Can add value and reduce wasted space.

Yes—when insulated correctly and provided with appropriate heating and ventilation. We design this in from the start.

Yes. We can design built-in storage or retain a portion of the garage where practical.

Timescales vary with complexity, but many conversions complete faster than full extensions. We’ll provide a clear programme before starting.
