Loft Conversions in Horley, Reigate and all Locations in the Surrey and West Sussex Areas

Could you benefit from habitable space in one of the most underused parts of your home? If you have outgrown your property but prefer not to relocate because you love the area you live in, or if you are looking to increase the market resale value by adding an extra bedroom or a functional space for work or pursuing your passions, Greens Building Contractors would like to hear from you. We are a team of general and new home builders from Reigate.

Our company can design and build loft conversions in all locations across our home county of Surrey and in all surrounding West Sussex areas. You can view previous loft conversion projects, undertaken in nearby towns such as Dorking, East Grinstead, Guildford and Horley, in our website’s portfolio.

Choose us for loft conversions in any of the following designs and styles:


  • Rooflight Conversions
  • Dormer Conversions
  • Mansard Conversions
  • Hip-to-Gable Conversions

We will be there to offer our experience and expertise, and to guide you with advice on planning approval and permitted development rights.

Importantly, Greens Building Contractors can bring builders and trades to the project under the umbrella of our own company. Instead of having to find an architect and source your workforce from several different businesses, we can offer you turnkey solutions through a full project management service.

Rooflight Loft Conversions

A straightforward conversion where we install windows into the roof to give a loft more light, but without the need for extensive building work or upheaval.


Dormer Loft Conversions

The addition of a box-shaped structure from the existing roofline with vertical walls for more headspace and a further option to have rooflights installed.


Mansard Loft Conversions

Our builders and trades construct these loft conversions with a horizontal roof and a near-vertical back wall to substantially increase available room space.


Hip-to-Gable Loft Conversions

This design sees us convert the roof hip into a gable to add more internal loft space and is best suited to semi-detached properties in our trading area.

The value-added benefits of a project management service see us working in unison with your architect of choice to produce conceptual schematics with the appropriate design-and-build documentation for building control should the job require planning approval. We can also consult with engineers so that any structural modifications can be made safely. From there, our company will provide a start date for the project and order in the required materials.

Previous clients in Reigate, and many from Dorking, East Grinstead, Guildford and Horley, have expressed concerns about disruption during a project.

Greens Building Contractors is an understanding service provider with a keen interest in your wellbeing. Because loft conversions typically start through the roof, your home won’t be affected by our builders and tradespeople until the later stages of the job where we need to come in to finish the interior, and to make important additions to grant access, usually with steps or ladders.
