How we work

Step 1
Initially, we will ask you to send us your email, site address and a brief outline of your proposed build. We will then examine your plot online (using Google Earth) to see if what you want is structurally achievable. After this initial analysis, we will send you a quote, via email, detailing the cost of the services we provide, which will allow you to obtain Planning Permission or Building Regulation approval.

Step 2
If you are happy with the quote and wish to proceed with us, we will arrange to come and complete a survey of your property. This will include taking measurements and photos of both the interior and exterior of the building so that planning drawings can be accurately drawn up.  

Step 3 
Once we have completed the first draft of your drawings, you will be sent a link (see example below) for you to review and discuss any changes you feel are necessary. 

Step 4
When you are happy with the completed final drawings, we will then progress onto the construction drawings and engineering calculations, so that they can be checked and approved by Building Contol, ready for you to start your build.
