Halkin Mews runs south off Motcomb Street, opposite The Turk's Head Pub. A narrow entrance leads into a cobbled courtyard.

It is a delightful Belgravia backwater.

No. 3 was built to a quirky design. There are interesting carvings of a Madonna and Child on the façade at ground floor level. There is an interesting false window at second floor level, concealing a roof terrace.

No. 15 is an unassuming brick-faced house made very attractive by a profusion of potted flowers and shrubs in front.
