Case study · Dulwich · Airspace and conversion

From MOT centre to 7 homes

A developer bought an MOT testing centre in a Dulwich mews and won planning to change it from B2 to residential use. We kept and strengthened the existing steel frame, added two new storeys with 5 apartments on top, and converted the ground floor into 2 more.

A tight mews site

The only access was a private drive behind a row of shops. Every delivery and machine movement was planned in advance, all the way through the build.

Foundations fixed early

Opening up the old foundations showed they couldn't take the new loads. We spotted it at the start, helped redesign them with piles and ground beams, and kept the job moving.

“To a very high visual standard, enhancing the surroundings.”

Ealing – 21 new build apartments in three blocks, built by Kisiel Group as main contractor
Case study · Ealing · Ground-up new build

Hired again. Third scheme for the same developer.

We'd already built two award-winning schemes for this developer in Ealing, so they appointed us main contractor for their largest: 21 new apartments across three blocks.

Block A has a basement level with two duplex apartments opening onto private courtyard gardens. Planning was refused in 2017 and won on appeal in May 2019. We started on site in December 2020 and the scheme is complete.
