  • Single or double-storey house extensions

  • Kitchen and diner extensions

  • Loft, attic, garage or basement conversions

  • Garden room extensions

  • Utility room extensions

Costs to expect

Costs of extensions and conversions vary depending on size, structure and spec, but here's a rough guide:

Single - storey extensions: £21,000 - £65,000

Double - storey extensions: £55,000 - £95,000

Loft conversions: £35,000 - £65,000

Garage conversions: £8,000 - £20,000

What to check before you hire:

  • Are drawings or planning permissions needed?
  • Are they familiar with building regs?
  • Is the quote fixed or flexible?
  • Does it cover materials and project management?

Most builders will include prep, construction, electrics, plumbing and final finishes in their quote, but always double-check. Timelines range from a few weeks for simple jobs to several months for bigger builds.

Extension and conversion builders in Great Malvern: Homeowners vs renters

Homeowners:

You’re in charge of the project. That means hiring the builder, securing permissions, and paying for the work. You may need:

  • Planning permission (especially for double-storey builds or changes near boundaries)

  • Drawings from an architect or structural engineer

  • Building regs approval

If you’re not sure where to start, speak to a local builder or post your job to get help with the process.

Renters:

You’ll usually need your landlord’s approval to make any big changes. In most cases, your landlord will be the one arranging and paying for structural changes like loft conversions or extensions. That said, it’s worth flagging ideas if you think they’ll improve the property, especially if it means longer tenancies or fewer repairs.
