Covering Hertfordshire and surrounding areas, Mammoth Landscape Build was established in 2010 by Dane Treadwell.  An experienced bricklayer by trade, specialising in creating high quality outside spaces, Dane is a perfectionist, renowned for ensuring that all projects are impeccably finished to a high standard.

Through mainly word-of-mouth, Mammoth Landscape Build has gained a reputation as a professional, honest company that provides an exemplary high level of workmanship.  Since then, the team has grown, they have won multiple awards and gained accreditations with a number of manufacturers.

Our Approach

We understand how stressful it can be having landscaping work undertaken.  Every care is taken to respect your home and your neighbours, always keeping the customer front of mind when planning logistics.  We are always happy to discuss any concerns you may have whilst on site and we will keep you updated with progress of the job as we go along. We are a friendly and approachable team - please feel free to ask us anything.

The Mammoth team have full public liability insurance. For anything we are not qualified to do ourselves, we will bring in carefully selected tradesmen (for example, electricians).
