In 2024, East Suffolk Council approved planning permission for a substantial timber treehouse set within the wooded northeastern corner of a large garden in Leiston, Suffolk.
The key planning considerations were the impact on privacy for neighbouring properties, the potential effect on existing trees, and the scale and design of the structure. All three were resolved through careful design, louvred screening and an arboricultural impact assessment.
Tree House Approved Planning Permission by East Suffolk
I secured planning permission from East Suffolk Council for a treehouse at a property in Leiston, Suffolk.
The application property is a mid-20th century bungalow within the settlement boundary, set within a generous mature garden with established hedging to each boundary.
The proposed treehouse is a substantial structure — consisting of two wooden platforms, a landing platform with a ladder to ground level, and a walkway connecting to a larger platform which forms a balcony to the treehouse itself.
Whilst large in total area when the platforms are included, the Council was satisfied the scale was not excessive given the size of the plot, and that the overall appearance remained subordinate in character.
Some planning matters required careful attention.
Privacy was the main concern. The treehouse and its elevated platforms created a potential overlooking risk to neighbouring properties, despite the site's mature screening. This was addressed directly in the design: louvred timber screening panels were incorporated into the raised platforms to limit sightlines onto neighbouring gardens and homes, whilst retaining an open feel to the structure.
Arboriculture was the second matter. The treehouse was to be constructed around and between existing trees, which raised questions about potential damage to root systems and trunks. An arboricultural impact assessment demonstrated that the structure, built on timber posts rather than relying on the trees for structural support, would not cause harm to the root systems or the long-term health of the trees.
East Suffolk Council agreed all three matters were resolved and granted planning permission.
