Da Vinci House involved the construction of three new levels over an existing building, to form two penthouses of 750sqm plus over 300sqm of roof gardens. The building sits on a tight urban site at the corner of Saffron Hill with St Cross Street, close to Farringdon Station.


The original 5 storey building was previously commercial in use – we understand it housed the printing works for the former ‘Punch’ magazine - and was converted to residential apartments in 1995.
The entrance halls to both penthouses are at the heart of the design, and are designed to lead visitors up to main reception areas on the upper levels.

Double-height spaces open onto long vistas over London, with St Pauls and the Shard in the distance, and maximise daylight.

The circulation within the apartment responds to the London skyline, opening up the interior to dramatic framed views.

In order to minimise the impact over the existing building below, the three new floors were constructed using a lightweight steel frame.




The vents for the air-conditioning to the kitchen were completely concealed, transformed into a series of tall slots acting as a light feature.
