Master Tradesmen in Cobham

Hayman Developments is a firm of high-end tradesmen based in Cobham. We specialise in providing property extensions and conversions to discerning clients across Cobham. References from previous clients are available upon request.


We have an outstanding reputation with private, executive and high-end commercial clients across the area. The reasons for this are our outstanding craftsmanship and our tireless dedication to customer service. As a family business, this dedication to providing only the highest level of building work is very much in the blood.


Our company works with its clients in and around Cobham to create made to measure building work that is completely unique. Whether you need loft conversions or home extensions, our creative architects and skilled craftsmen have the skills we need to realise your vision from design to completion.


Our loft conversions are an ideal way to create more space, especially if exterior space limitations render extending outwards impossible. Similarly, if you have an unused barn or garage on your land, our conversions can give you extra space while also preserving the character of its exterior.

The idea of undertaking any kind of property conversions can be daunting, especially when it involves alterations to period or luxury homes. With this in mind, we at Hayman Developments offer advice and support throughout the project. Upon request, we will apply for planning permission on your behalf.


We work on both ultra-modern contemporary projects and those that require us to return a period property to its former glory. We can even provide a mixture of both to give your traditional home or office a subtle modern twist that incorporates modern conveniences.


With our team of experts, you can be sure that you will be satisfied with our work both during the project and on its completion. We are available for design work or just a section of the building work, or for home extensions or extensive renovations in Cobham and the wider Surrey area. However large or small the job at hand, we provide peerless attention to detail and professionalism in everything we do.
