Can protected trees stop a garden structure?
Yes. Protected trees can mean moving, redesigning or abandoning the proposed installation. Before ordering, check tree status with the relevant council and have an arboricultural adviser assess foundations and delivery access. Coordinate the resulting factory drawing changes with Cambridge China Bridge.
Check the trees before choosing the structure
The detailed tree rules here concern England. For Scotland, Wales or Northern Ireland, start with the relevant council and national guidance. Send the council's tree or planning team the site address, photographs and a layout showing nearby trees, including those across boundaries. Ask them to confirm any Tree Preservation Orders, conservation area designation and tree-related planning conditions.
Request the relevant order and plan so your adviser can match the protection to the actual trees. Ask about the proposed excavation, pruning and access route, rather than simply whether a garden room is allowed. Our garden room and pergola permissions guide covers the wider planning and building-control checks.
Resolve the tree-work permission route
In England, government guidance treats cutting roots of a tree protected by a Tree Preservation Order as requiring council consent. Permitted development rights do not remove the consent requirement for protected-tree work needed to carry out that development. Ask the council to identify the application route for your exact proposal.
For conservation area trees, ask whether prior notice is needed, which work it covers and when work may begin. Have the adviser resolve any claimed exception with the council. As a buying precaution, keep the order on hold until the applicable permissions or notice process have been resolved and the installation method is settled.
Have foundations assessed alongside the roots
Commission a qualified arboricultural consultant to assess the trees and advise on root protection. Give them the proposed footprint, foundation details, service trenches, drainage and ground-level changes. Ask for a plan showing protected working areas and a method for construction near roots, coordinated with the foundation designer.
Excavation can sever roots, while changes to soil conditions can affect them without visible damage above ground. Ask the advisers to compare moving the structure with changing its supports. Do not assume ground screws, pads or a raised base avoid root damage. Obtain factory drawings showing support positions, loads and anchoring assumptions before accepting a foundation proposal.
Include unloading and delivery access
Review the whole route from the unloading point to the final position. Vehicles and repeated handling can compact soil around roots; crane supports and stored materials also deserve review. Mark turning areas, lifting positions, temporary storage and any branches that obstruct the route. Ask the arboricultural adviser and delivery contractor to agree suitable protection and working limits.
Get packed dimensions, package weights and handling instructions from the factory before booking delivery. If the reviewed route cannot accommodate the proposed packages, discuss smaller assemblies or a different unloading arrangement before production. Use our container and oversized delivery guide to prepare the transport brief.

Make the reviewed design part of the order
Keep the council correspondence, relevant decisions, arboricultural advice, foundation design and delivery plan together. Name who resolves conflicts between them. Agree what happens if site investigations reveal roots where supports were planned, including who stops work, obtains advice and approves changes. Avoid leaving that decision to the delivery crew.
Ask Cambridge China Bridge's own staff in China to obtain revised factory drawings and confirm package details against the agreed site plan. Record the accepted revision and require buyer approval before changing support positions or package sizes. Our product specification guide explains how to put the agreed details into the order.
Frequently asked questions
Can a protected tree stop me installing a pergola?
Yes, it can make the proposed position or installation method unsuitable. Ask the council about tree protection and have an arboricultural consultant review foundations and access before ordering.
How far from a protected tree can I build?
Do not choose a clearance from a supplier's generic diagram. Ask an arboricultural consultant to assess the actual tree, roots, ground conditions and proposed works, then coordinate the layout with the designer.
Are ground screws safe near tree roots?
Do not assume so. Have the arboricultural consultant and foundation designer assess screw positions, installation disturbance and structural loads before accepting the system.
What if delivery needs branches cutting back?
Show the proposed pruning and delivery route to the council and arboricultural adviser before booking. Consider different packaging or handling arrangements and resolve any necessary tree-work permission first.
