Plans to redevelop Dorchester’s former Marks & Spencer site into a 102-room Premier Inn have been abandoned, with rising construction costs and increased business rates cited as the key factors. Whitbread, which owns the Premier Inn brand, purchased the South Street site in 2023, with proposals to demolish the existing buildings – a mix of 1930s and Victorian architecture – and replace them with a modern hotel. The scheme had been expected to bring an estimated £3m boost to the local economy.
However, the company has now confirmed it will not proceed.

In a statement, Whitbread said the project was ‘no longer viable’ following a review of costs, adding that the site will be put up for sale in the coming weeks.
The decision leaves a prominent town centre site, vacant since M&S closed in 2020, once again without a clear future.
Whitbread already operates a Premier Inn at Brewery Square, and had positioned the second hotel as a way to meet growing demand for overnight stays in the town. The withdrawal suggests that, even in well-located market towns, development viability is becoming more finely balanced.
Steve Bulley, president of Dorchester Chamber for Business, described the news as ‘a shock’ and said it had come ‘out of the blue’. He indicated the site could now be reconsidered for a mixed-use scheme, potentially combining retail at ground level with residential above.
The South Street site has long been seen as a key regeneration opportunity. Its extended vacancy has become increasingly visible in the town centre, and there is likely to be pressure for a quicker, more flexible redevelopment approach once a new buyer is found.
‘The site also carries historical significance. During construction work in 1936, builders uncovered the Dorchester Hoard – more than 22,000 Roman coins – adding another layer of interest to any future plans.
For now, attention turns to what comes next, and whether a different model – potentially less capital-intensive than a hotel development – proves more viable in the current climate.
