Practical points for boundary work in Mill Hill Broadway
Boundary treatments for flats and maisonettes
Shared amenity gardens attached to flats or maisonettes usually have boundary decisions made collectively through a management company or freeholder rather than by an individual leaseholder, which changes who needs to sign off a fence or gate change.
Lease terms sometimes specify who's responsible for maintaining which boundary, and altering a shared boundary without checking the lease is a common source of dispute between leaseholders.
Where several flats share a single rear garden, dividing it with new fencing usually needs agreement from all affected leaseholders, not just the person requesting the work.
Pergola and screen timbers
Pergola posts generally need a larger section than a fence post of the same height, since they carry a horizontal beam and roof structure rather than just resisting wind on a flat panel, and undersized posts show up as noticeable sway at the top rather than immediate failure.
Softwood pergolas are almost always pressure-treated given the exposure, while a hardwood pergola can be left to weather untreated in the same way an oak gate can, at a higher initial material cost.
Screening timbers fixed to or beside a pergola structure follow the same gap and profile logic as free-standing slatted fencing, so the same trade-offs between privacy, light and wind loading apply.
Ongoing access rights reserved under a utility wayleave
A recorded wayleave or easement for utility apparatus usually reserves an ongoing right for the utility company to access and maintain their equipment, which can mean a fence built across the strip needs a lockable gate or removable section.
Building an entirely fixed fence over an area subject to this kind of reserved access can lead to the utility company needing to remove part of it later at the owner's inconvenience.
Checking the title register for any registered wayleave before finalising a fence design avoids this kind of retrofit.
Listed building curtilage and garden boundaries
Structures within the curtilage of a listed building — which can include garden walls, gate piers and sometimes fencing — may themselves be treated as part of the listing, even if not mentioned explicitly.
That means listed building consent can be required for work that would otherwise be unremarkable on a non-listed property, and doing work without consent where it's needed is a criminal offence.
Anyone unsure whether their boundary falls within this kind of curtilage should raise it with the council's conservation or listed buildings officer before starting.
Waste carrier duty of care for site waste
Anyone removing fencing, decking or building waste from a client's property in the course of business needs to be a registered waste carrier with the Environment Agency, and should be able to provide a waste transfer note showing where the material was taken.
Treated timber, in particular, is classed differently to plain untreated offcuts and generally can't simply go on a bonfire or into general household waste, since some older preservatives fall under hazardous waste rules.
Asking a contractor for their waste carrier registration number and a transfer note isn't excessive caution — the householder can be liable if waste is later found fly-tipped and traced back to the job.
Waste carrier duty of care for old fencing
Under the Environmental Protection Act 1990, anyone arranging removal of construction waste such as old fence panels and posts has a 'duty of care' to ensure it's handled by a registered waste carrier.
Asking to see a waste carrier's registration number, and requesting a waste transfer note for larger quantities, is a reasonable and legitimate request rather than an unusual one.
Householders can be held responsible if waste from their property is later found fly-tipped, even where they paid someone else to take it away, which is why checking credentials matters.
