We drew up a Tree Safety Policy and carry out annual Tree Hazard Assessments  for this 500ha site, attracting 200,000 visits each year.

A development, situated in an Area of Outstanding Natural Beauty, where arboricultural site supervision helped ensure an environment enhanced by retained mature trees.

We prepared a Tree Constraints Plan and Arboricultural Impact Assessment  covering over 100ha for award-winning heritage developer City & Country.

Sonning Common

We prepared an Arboricultural Impact Assessment for a new garage, constructed within the Root Protection Area of a protected oak tree. No-dig construction was used with a raised concrete slab. Rainwater from the roof is fed back under the slab to maintain moisture levels.


Dulwich College

We surveyed all trees on the main college site in 2013 and produced a Tree Constraints Plan which helped to inform the college’s development plans. Arboricultural Impact Assessments have since been undertaken for a new Science Building, a link building between two boarding houses and for a landscape masterplan.

We prepared a woodland management plan to support a planning application to create a retirement community on the site of a former edwardian estate, more recently used for holiday chalets. The 25 year plan will regenerate neglected woodland, improve amenity value and biodiversity, while opening up paths and a folly, “lost” since the 1930’s.
