Property Extension in Storrington, Steyning and Locations in the West Sussex Area

Having a property extension built by the builders at Kirk Building & Carpentry is one of the most cost-effective ways to increase a home’s footprint and gain the habitable living space your family needs. It is understandable than many homeowners won’t want to part with the memories of their families growing up in a property or might not have the finances available to upscale. We can help you to stay in the home you love by extending it for a specific purpose.

Benefit from extra living space, a productive home office, a playroom for the children or a home cinema room with the latest audiovisual equipment. Some customers choose our services to extend their kitchens and bathrooms.

The choice, however, is always up to you.

Kirk Building & Carpentry can build property extensions in Haywards Heath, Horsham, Hove, Steyning, Storrington and all West Sussex areas.

We can also increase habitable room space with bespoke loft conversions.

Having an Extension Built

It is important to consider how you would like to use a property extension prior to calling us so that we can design and build to the correct specification. To gain the largest amount of space, a double-storey extension can give your home an extra bedroom upstairs, and a purpose-built area for the bottom floor. Building over two storeys optimises the project and, if you ever decide to relocate, this type of build offers the biggest return on your investment.

Because Kirk Building & Carpentry can manage the construction of property extensions from the conceptual stage through to completion, you will only need one team of builders and trades instead of using multiple companies.

We deliver turnkey solutions that work for our customers and clients.

Extension styles include:

  • Rear-Facing
  • Side-Return
  • Wraparound
  • Over-Structure

Our service covers the survey and consultation, compiling a detailed written quotation with labour and material costs, a site clearance of the proposed workspace, groundworks, drainage installation and pouring the foundations.


We then build the shell and add the roof to keep everything watertight.

Kirk Building & Carpentry brings all trades to site so that a property extension is an in-house project. We have carpenters and joiners on our team who offer support to our builders, and we can further supply the job with accredited electricians, plumbers and gas engineers for the 1st-fix and 2nd-fix stages.

Not all extensions require planning approval but for those that do, we advise on applications and manage all communications with building control.

We strongly believe that every homeowner in the Haywards Heath, Horsham, Hove, Steyning and Storrington areas, and those across West Sussex, deserve an ethical and cost-effective service built around professional delivery and the results they wish to achieve. A property extension from Kirk Building & Carpentry is an investment into your future, and we protect that investment by guaranteeing our workmanship and honouring all material warranties.

Avoid the cost of relocation by calling us today and extend your home in a choice of styles which tie in perfectly with the way you like to live.
