Neighbours in Bath are calling for the demolition of a “mega mansion” believed to be the largest newbuild home constructed in the city in the past century, following concerns it was built without proper planning permission. The substantial property, situated on the outskirts of Bath, has reportedly exceeded approved plans in both height and footprint, causing significant unease among local residents.
Tavis Hamilton, 48, who lives adjacent to the property, has spent a decade challenging various developers over the site. He is among more than 100 residents who have formally objected to the construction, fearing that local council enforcement may be too late to address the breaches adequately.
The building is nearly complete, having been “topped out,” and a retrospective planning application was recently submitted in an attempt to legitimise the substantial alterations from the original consent. However, some locals argue that this situation underlines how wealthier individuals exploit loopholes and manipulate the planning system.

Bath and North-East Somerset Council declined to comment in detail but noted that enforcement actions would only be considered after the retrospective application has been reviewed.
Mr Hamilton described the completed structure as “enormous,” estimating its value to exceed £3 million, and said it dwarfs neighbouring traditional cottages, with its footprint comparable to that of 24 such homes. “It’s been built over three years and now it’s clear how tall and imposing it is,” he said. He also highlighted the perceived inconsistencies in enforcement, contrasting the council’s swift action over minor infringements with the apparent tolerance for this large-scale unauthorised build.
At a recent site meeting, over 70 residents expressed their concerns, with more than 100 lodging formal objections. The original plans had approved a modest, single-storey building integrated into the hillside. However, complications when digging-such as hitting groundwater-led to substantial backfilling with concrete, resulting in the building sitting higher and in a different position than permitted.
The development has passed through three owners since 2007, with multiple planning applications aiming to increase its height and presence. Enforcement teams have confirmed deviations from approved plans, including increased height, larger size, and altered siting.
Mr Hamilton criticised the developer’s approach, accusing them of proceeding without regard for approval conditions and making unapproved changes that diminished the architectural quality of the property. He described the situation as “stressful and unsettling,” with residents uncertain about the final outcome.
Photos show work ongoing on finishing touches like skylights, but the overall massing and height are now visibly established. Mr Hamilton expressed concern over the impact on the character of the lane and nearby listed buildings, noting that “some residents call for its demolition,” though he is unsure if such enforcement is feasible.
The lane comprises traditional Bath stone Georgian properties, and residents highlight other concerns such as inappropriate landscaping and increased bedroom numbers from five to seven. The building’s orientation and position reportedly differ significantly from approved plans.
The developers claim they have kept the building as low as possible and that the overall height is similar to the original approval. They attribute changes to the challenging ground conditions encountered during construction.
The plot of land was initially sold for £1 million with planning permission in place, and extensive excavation reportedly added significant costs. Mr Hamilton said his home is now flanked by two large “monster mansions,” both unusually expansive for Bath.
Opponents suggest that the original developer secured permission for the maximum allowable size, then quickly sold the property. Subsequent owners sought to increase the building’s scale substantially.
According to council records, enforcement teams have identified serious discrepancies between the built structure and approved plans, including in positioning and sizing.
Local ward councillor Joanna Wright supports residents' calls for enforcement, criticising the ongoing changes and lack of effective council intervention. She said the case highlights frustration with perceived disparities in how planning regulations are applied based on developers' resources.
“This development is now larger and taller than the Grade II listed church next door,” she said, questioning how this was permitted. Miss Wright added that the narrow lane and close proximity of windows raise issues for neighbours’ privacy and amenity.
Bath and North-East Somerset Council confirmed the retrospective planning application is under consideration and noted enforcement would only proceed if the application is refused.
Representatives for the developer stated that changes were necessary due to ground conditions and practical considerations during construction, emphasising efforts to maintain the building’s height and overall appearance close to the approved plans.
The current house owner, Thomas Worrall from Yate near Bristol, expressed frustration about the opposition, insisting the original planning permission was in place upon his purchase. He acknowledged complications arising from ground conditions that necessitated design changes, but denied deliberately circumventing regulations.
Mr Worrall said construction has now paused while working with planners to resolve outstanding issues. He expressed a desire to complete the home and be a good neighbour, apologising for any inconvenience caused.
The situation remains unresolved, with the retrospective application under review and local residents continuing to voice concerns over the scale and legitimacy of the development in a historic area of Bath.
