Hello, My name is Karl Shippey, [HND Construction] and I run KAS Builders. I am a professional, friendly and approachable builder with 18 years experience, knowledge and skills of design, planning and construction with the aim of providing a high quality service to both the domestic and commercial building markets. I have undertaken projects successfully from large extensions to fixing leaking taps. I have a Project portfolio (see above) of previous work available along with customer references (see testimonials below). If you have any questions or require a quotation for work, please do not hesitate to contact me using the details at the base of this page.


Our services usually cover Bedfordshire, Buckinghamshire, Oxfordshire and Northamptonshire.
If you are interested in commissioning us to carry out a project, but are unsure if we cover your area, please contact us using the details at the base of this page or our site contact form.


Floor Tiling

Karl is a perfectionist who did a fantastic job installing the wood effect porcelain plank tiles in our hallway. He worked into the evening on the second day to get the job done to his and our satisfaction. Vistors are convinced that it is a real wood floor. I would definitely use KAS Builders again. Eric, MK17



 Stone / Concrete Paving

The work was done professionally and in the specified time. Karl is friendly, polite and a very good communicator. He updates the progress of the job daily. He gives genuine advice when asked. I have no hesitation in recommending him to anybody who needs any building work done, or using him myself again when needed. Excellent work!
Thanks Sherali, MK6



Laminate Flooring

The work carried out was laminate flooring replacement and decorating after minor flood. Additional damage was discovered as we were leaving on holiday. Karl was incredibly helpful in making enquiries with engineers while we were away. Very professional and reliable throughout the work. Would definitely recommend.
