Self Build Projects


To enable the Self Build to meet increasingly complex technical installations or to assist in traditional build methods, TCHI offer a full and personalised service covering everything from design, to construction supervision.


In todays market most of the drawings are created in CAD (computor aided design). These drawings are usually very basic with very little detail. Detail is very important, especially to the self build.

Local Authority Building controls will not refuse plans because they omit detail, but they will expect, all details to be supplied at some stage of the build.

Unless you've agreed a complete package from the supplier of your plans, you will end up paying considerably more and in some cases, thousands to have those details supplied.

Independent and good sound building advice from TCHI could save you on any unnecessary work and with the ever growing cost of labour and material we believe independent advice makes good sense.
