Sandbanks owner endured 25-year planning battle after demolishing boathouse
Simon Bowden, a 66-year-old former investment banker, spent 25 years in planning disputes after inadvertently torpedoing his own development plans by demolishing a 90-foot boathouse on his Sandbanks property. Having purchased the half-acre plot in 1998 for £820,000 with the delapidated boathouse already on site, Bowden knocked down the structure during major renovation works, only to discover that the 1920s-built boathouse had been exempt from new shoreline building regulations introduced in the late 1990s. This costly mistake exemplifies how planning regulations can create unexpected obstacles for property developers, even when their intentions are to improve their own property.
The rules prohibit construction within 82 feet of the waterfront in the exclusive Sandbanks peninsula, which were introduced to combat coastal erosion, manage flooding, and prevent the trend of demolishing original properties and replacing them with modern developments. After his initial planning application was rejected, Bowden spent a quarter-century navigating the planning system before finally receiving permission to build. He is now constructing a three-storey, architecturally distinctive five-bedroom home positioned away from the shoreline, carefully designed to respect over 50 protected trees on the property whilst maintaining a jetty connection to Poole Harbour and featuring an outdoor swimming pool.

New here? Start with this
Sandbanks is an exclusive waterfront district where strict planning rules protect the shoreline from erosion and flooding. Regulations introduced in the late 1990s prohibit construction within 82 feet of the water and were designed to preserve historic properties and prevent widespread redevelopment of the area.
Simon Bowden bought a Sandbanks property in 1998 that contained a deteriorating 1920s boathouse. When he demolished the structure as part of renovation work, he discovered that older buildings were exempt from the new shoreline regulations, meaning he could not rebuild anything in its former location.
Bowden's attempts to develop the rest of his property subsequently became entangled in a quarter-century of planning disputes. His experience illustrates how changes in building regulations can have unexpected consequences for property owners, even when their intentions are to improve their own land.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Property owners should retain reasonable autonomy to develop their own land, particularly when newly introduced regulations were not universally understood and when the affected structure was already exempt before restriction. A 25-year dispute for an inadvertent mistake seems disproportionate and punitive, especially where the owner's final design respects environmental concerns through shoreline distance and tree preservation. Rigid planning systems that inflexibly prevent reasonable development proposals can inhibit productive use of private property and may be counterproductive to their stated aims.
The case against
Shoreline regulations exist to prevent coastal erosion, manage flooding, and protect the character of valued communities—purposes that require consistent enforcement rather than discretionary exemptions. Once exceptions are granted for property owners who demolish exempt structures, the rules lose their protective force and create perverse incentives for others to demolish protected buildings first and seek retrospective permission later. The principle of equal application under law matters; allowing special pleading from wealthy property owners based on claimed ignorance would fundamentally weaken planning protection for everyone.
