About Us

KDH are a specialist UK based company providing 2D CAD (computer aided design) conversion and drafting, 3D modeling, solid modeling and drawing scanning services. Founded in 1990, at the heart of our ethos is to provide customers with a competitively-priced range of professional drawing office services. As well as having a strong reputation for our professionalism and high standards, we always aim to turnaround your work as quickly as possible - it's not unknown for us to deliver CAD drawings within 24 hours!


We are BS EN ISO 9001:2008 certified for the quality of our work and have over 200 previous (and very happy) customers (see testimonials), ranging from private individuals to large corporations – all of them can vouch for the high standard of the CAD services we provide.


Big clients we have worked with include HM Prisons Service, Scottish Prisons Service, Essex County Council, Wiltshire County Council, Anglesey Aluminium, Surrey County Council and Nalco, amongst others. More recently, we’ve tendered for and won a major five year contract with one of the world's leading facilities management companies as well.


However, whilst we like to work with big companies, we also like the variety provided by our private clients. All of our customers – no matter how big or small – can rely on us to provide them with the same great level of service and care for which KDH has become renowned.

  • 2D AutoCAD or Microstation drafting
    We provide an affordable and quality 2D AutoCAD or Microstation drafting service from your marked up drawings, pdfs, jpgs, dimensioned sketches and redlined drawings.
  • 3D CAD photorealistic drawings or solid models
    Nothing can come closer to seeing how a project will look, than a 3D CAD photorealistic drawing or model from KDH. These can be created from your drawings held on 2D CAD dwg/dgn, paper, pdf, jpg, tiff, solid parts, etc.
  • Measured building surveys
    We offer measured buildings surveys to facilitate the accurate production of 2D or 3D floor plans and, if required, elevations.
  • CAD software
    We offer ZWCAD software - we think this is a slick, serious and professional rival to AutoCAD!




I was extremely impressed by the quality of the CAD conversions, and it has got the attention of some others....
