Small Sites Metric

Hi, I'm looking for someone to carry out a BNG assessment (Small Sites Metric). The purpose of the development is to divide a large garden in order to add one residential dwelling. There is a clear vision for what I want the design to look like (approximately as last slide in the attached) and at this stage, the application is outline only. I'm looking for someone with the appropriate experience and required qualifications to get this done quickly and efficiently. If you believe you can provide this please make contact with me.

I've no idea of the time this would require - and therefore the cost - so please enlighten me

Greg
