We are happy to work with clients who for whatever reason wish to complete either 'self-build' projects from just producing designs and plans through to full Contract administration and Site Supervision.

Designs to meet your requirements - we can design your project with lots of Architectural features or as a no frills budget design with cost per m2 of building as the main criteria or somewhere in between. However, we try to blend any extension to the existing and won't design something that will devalue your house (we have had customer suggestions in the past that would do just that!). We will voice our opinion and offer advice against those suggestions
