The three shortlisted finalists – Sewell, Matthew Beesley from Cheshire and Sam Hunt from Gloucestershire - partnered the three finalists in the RHS Young Planting Designer 2016 competition to build and plant a garden designed by the 2015 RHS Young Designer Tamara Bridge.
Sewell's garden – a Coastal Retreat – was deemed by the judges to be worthy of Gold and with the announcement that he had won the RHS Young Landscape Contractor title the Best Construction award was probably a foregone conclusion.
In a statement, BALI said: "On announcing its support for the Young Landscape Contractor competition in the spring, BALI hoped it would provide a platform from which the UK's largest trade body for the landscape industry could promote its key messages of quality, expertise and all round professionalism whilst raising the profile of professional landscaping as a career choice for young people.
"The success of the competition, both in terms of the achievements of the young people taking part and in the incredible interest generated at the show, has certainly secured its future as a major competition for young people aspiring to succeed in the industry."
Sewell, and the winner of the RHS Young Planting Designer 2016 competition Katie Maude from Manchester, received their awards yesterday from RHS director general Sue Biggs and BALI chief executive Wayne Grills. Horticulturist and TV personality Monty Don was also at the presentation.
Grills said: "I am delighted with how successful this competition has been and by the incredible achievements of all six of the young people who competed to create such impressive gardens.
"In the true spirit of the competition each pair worked as a team to create three different takes on the garden designer's plan. With all three gardens receiving a Gold medal it must have been an extremely difficult call for the judges to select the two winners."
He continued: "Ewan has shown that youth is no barrier to achieving professional excellence and I predict great things for him in the future. I hope he will use his success to be an advocate for the industry, encouraging other young people to consider landscaping as a career.
"I look forward to the time when BALI can welcome him as a member of the association in his own right and wish him every success with his future career."
