The facts

Retail to residential conversion, Solihull.

Much of the store's trade had moved online and it no longer needed three floors. A commercial unit still faces Stratford Road; the rest of the building became 18 apartments, six of them wholly or partly in new-built extensions.

Three gables across the front.

The approved front: three gables across the whole frontage with a bay window under each, one fascia over the commercial unit, rooflights in the roof, and gates at the left to the bin store and side passage.

What the council decided

Granted, with a commercial front kept.

Granted, 5 February 2021.

Solihull Council granted 18 apartments and a flexible commercial unit. Its policy team found that, with commercial use still facing the A34, the loss of the shop did not conflict with the local plan.

No affordable homes were required. The council's housing team worked out that 18 apartments would normally carry seven on site; the vacant building credit for the existing floorspace cut that to 0.55 of a home, which its policy rounds down to none.

The full story

342 Stratford Road is a deep, narrow building on the A34, just south of Shirley town centre. It was a furniture store, with retail and offices on all three floors, about 1,090 sqm in all, and the business was selling more and more online. A 2019 permission already allowed three shop units and 11 apartments.

We already knew the building. In 2019 and early 2020 we had worked on the drawings to build that permission, from the strip-out to the structure. In October 2020 the brief changed: more homes than the 2019 permission allowed, with commercial space still facing the street.

We tested how many homes the building could take against how much shop to keep. An early layout had 17 flats and a larger commercial unit; moving one more flat onto the ground floor gave 18. A flexible commercial unit of 115 sqm keeps a frontage to Stratford Road; behind and above it are 18 apartments: two studios, five one-bed and eleven two-bed.

Twelve are inside the existing building and six are wholly or partly in new-built extensions, including a new top floor over the front and middle of the building. The neighbour's wall runs along the north side, where no windows are possible, so two light wells bring daylight into the middle of the plan. There is no parking: the scheme was put forward as car-free on a main bus route, with cycle storage for every flat.

Before applying, we sent the drawings to the council's planning officer to discuss affordable housing. The officer asked for the existing and proposed floor areas, and in October 2020 confirmed in writing that there would be no affordable housing obligation.

Solihull Council registered the application in November 2020 and granted permission, PL/2020/02587/PPFL, on 5 February 2021. The council's policy team found that, with commercial use still facing the A34, the loss of the shop did not conflict with the local plan, and the vacant building credit took the affordable housing obligation from seven homes to none.

While the council decided, the 2019 scheme stayed the fallback: the building control notice given in November 2020 was for its 11 flats. Five days after the new permission, the notice was amended to the 18 apartments.

After consent we produced the technical design and made the five applications that followed before completion: a front rooflight by non-material amendment in April 2021 (PL/2021/01024/NONMC); the materials, drainage, sound insulation and construction management conditions, discharged in three decisions between August 2021 and July 2022; and a second amendment in January 2023 (PL/2023/00030/NONMC) covering window sizes, a second front rooflight and access to the bin store for the water company, whose sewer runs within the site. Work started on site in June 2021.

We issued the final construction drawings in October 2022, and they went into the building's health and safety file. The pre-completion sound tests all passed, including those between the commercial unit and the flats. Building control signed the building off in three steps: the twelve converted flats on 10 March 2023, the commercial unit on 30 March and the whole building on 12 April 2023, when the approved inspector issued the final certificate.
