Stanwell Hotel Approved: 53 Bedrooms Become 96

Spelthorne Borough Council has granted planning permission for the expansion and refurbishment of the Stanwell Hotel at 171 Town Lane. The decision notice is dated 10 September 2026 and the reference is 26/00418/FUL.

The approved scheme raises the number of ensuite bedrooms from 53 to 96. It was decided by officers under delegated powers, not by councillors: Spelthorne’s planning committee meeting on 16 September was cancelled, and the register records both the expected and the actual decision level as a delegated decision.

Twenty-two residents wrote in to object. One wrote in support.

We have read the decision notice and the delegated officer’s report rather than the coverage of them. Four things in the council’s own papers are worth knowing.

What was approved

The permission covers:

• a flat-roofed single-storey rear extension adjoining the existing ‘stable block’, providing 15 new rooms and a linen room, about 3.2 metres high and set in at least 0.5 metres from the boundary
• a second-floor extension behind the main front roof, raising the building by 1.2 metres, with roof dormers
• internal alterations that account for the rest of the increase to 96 ensuite bedrooms
• a glazed link canopy between the stable block and the main building
• new refuse, recycling and cycle storage areas
• a reconfigured car park with a minibus and taxi drop-off in front of the main entrance

Six of the 15 new ground-floor rooms nearest the boundary fence would have rooflights rather than windows.

The applicant’s own application form states the scheme would take the hotel from 4 full-time staff to 15, and from 6 part-time staff to 20. The officer’s report weighs that increase in employment in favour of the scheme under the local plan’s employment policy.

The parking argument, and how it was settled

Parking was the planning issue that nearly stopped this.

The site keeps its existing 42 car parking spaces, including 3 for Blue Badge holders and 8 for electric vehicles. There are three accesses, one off Trinity Close and two off Town Lane, and all three are retained, with Trinity Close as the primary access.

Surrey County Council’s parking guidance points to 1.5 spaces per bedroom, which for 96 rooms would be 144 spaces. That figure is a maximum standard rather than a requirement, a point the officer’s report makes explicitly.

The County Highway Authority originally objected, saying substantial parking demand would be displaced onto surrounding residential streets in a way that might compromise the safety and operation of the highway.

The applicant answered with a beat survey of on-street capacity carried out in June 2026. The highway authority’s reading of it is that, averaged over the two nights surveyed, 42 on-street spaces were available. It accepted there is potential for overspill parking to have a noticeable impact on surrounding roads in peak seasons, but concluded that the survey results plus the proposed mitigation removed any significant highway safety concern. It withdrew its objection subject to conditions.

The officer’s report adds a second argument that residents may find more uncomfortable. The site already holds an extant permission from 2021, reference 20/00421/FUL, for 12 extra bedrooms with 48 parking spaces, kept alive by a certificate of lawfulness granted in December 2024. Between that permission and internal alterations, the report says, 32 extra rooms could be provided anyway, taking the hotel to 85 rooms with the same 42 spaces and no new decision needed.

Town Lane gets two bus stops, a crossing and double yellow lines

The most concrete thing in this permission for people who live nearby is condition 5, which the developer must deliver through a Section 278 agreement with Surrey County Council before any part of the development is first occupied.

It requires:

• the upgrade of both the northbound and southbound Town Lane bus stops, to include real time passenger information, access-for-all kerbing, shelters, seating, lighting, power, bus cages and an enforceable clearway
• an informal pedestrian crossing point over Town Lane, with dropped kerbs and tactile paving
• parking restrictions including double yellow lines along Town Lane and nearby junctions

The double yellows are not automatic. An informative on the permission confirms a Traffic Regulation Order is a separate statutory process, paid for by the developer, and that if it fails because of unresolved objections the applicant must agree alternative mitigation with the highway authority instead.

Other conditions require a construction transport management plan before work starts, covered and lit cycle parking for at least eight bikes with e-bike charging points, and fast electric vehicle charge points on at least half of all available parking spaces before occupation, with cable routes for the other half.

What the council said about the asylum contract, and what it did not

The hotel has been contracted with the Home Office since 2022 to provide accommodation to migrants. That is stated as fact in the officer’s report’s description of the site.

Objectors raised the asylum use directly, along with safety and security concerns. The officer’s reply is printed in the report, and it is narrower than the headlines about this decision suggest:

This application proposes to convert the use back to a regular hotel, however this cannot be controlled by planning.

The same section records the officer’s answers to other objections. Potholes on the road are a matter for Surrey County Council. The hotel being inaccessible to the general public cannot be controlled by planning because the site is privately owned. Property values and the owners’ motives are not material planning considerations.

So the permission does not end the Home Office contract, and nothing in it requires the hotel to stop being used that way. It grants the physical works. What happens to the contract is a matter between the Home Office and the operator, and the council has no planning lever over it either way.

Objectors also raised the impact on the character of the area and the nearby conservation area, loss of privacy and overlooking, noise from construction and occupancy, litter and grounds maintenance, traffic and emergency vehicle access. The officer concluded the extensions would not detract from the character of the area and that the impact on homes in Atherton Close and Trinity Close was acceptable, largely because the rear extension is single storey and its new windows sit at ground floor level behind an existing boundary fence.

The rest of the file

A large tree at the front of the site and trees at the rear are covered by Tree Preservation Orders. The council’s tree officer advised the works would not affect them.

Surrey Wildlife Trust asked for more on bats and biodiversity. The applicant confirmed no bats were recorded in the structures, and that biodiversity net gain will be delivered off site because it cannot be achieved on site. The trust recommended a landscape and ecological management plan and an ecological enhancement plan as pre-commencement conditions; the officer judged those unreasonable given the off-site provision and the relatively small scale of operational development, and did not impose them. A biodiversity gain plan must still be approved before work begins, under the statutory condition that applies automatically.

The council’s climate change officer initially found that on-site renewable energy generation had not been maximised. The applicant submitted further justification for its solar approach, which the officer then accepted.

Because the site is within 6km of Heathrow, any crane on site needs details filed with the Civil Aviation Authority and a permit issued by Heathrow’s works approval team before it can operate. The site also sits inside the Spelthorne Air Quality Management Area, so signage telling drivers to switch off engines is required in the drop-off and parking areas.

The application was received on 23 April and validated on 6 May 2026. Its original determination deadline was 1 July. Extensions of time were agreed to 11 September so the applicant could answer consultees and neighbours could be re-notified of amended plans. The case officer was Kiran Boparai.

What it means for you

• The work has not started and cannot start yet. A biodiversity gain plan, a construction transport management plan and materials details all have to be approved first. Permission lasts three years from 10 September 2026.
• If you live on Town Lane, Trinity Close or Atherton Close, the bus stop upgrades, the pedestrian crossing and the double yellow lines are tied to first occupation, not to the start of building. Watch for the Traffic Regulation Order consultation, because that is the stage at which the yellow lines can still be objected to.
• Construction hours are advisory, not a condition. The council expects audible work between 8am and 6pm Monday to Friday and 8am to 1pm on Saturday, with none on Sundays or bank holidays. If that is breached, the route is the council’s environmental health team rather than planning enforcement.
• There is a named contact route for complaints during construction. An informative requires the developer to publish a site manager’s name and contact details and to answer the phone during working hours.
• Anyone can read the file. Search 26/00418/FUL on the council’s planning register for the decision notice, the officer’s report and every plan.
