3 Savile Row: 1962 - 2009.

Above, 3 images of 3 Savile Row's exterior. On the left is how the building looked in the years before housing Apple. At that point (the picture is ca.1962), the building was known as Hylton House, Jack Hylton being a hugely successful bandleader and theatrical impresario who had number 3 as his headquarters. The Beatles bought the lease from his estate in June, 1968.
The middle picture dates from 1976; the building, though still owned by Apple, lies empty, having just undergone extensive renovation and reconstruction (more on this soon). The final image is from this year - and the exterior looks remarkably similar.
Below, 3 images of 3 Savile Row's interior. Today, thanks to multiple subsequent makeovers, much of the indoor area would be unrecognisable to the various waifs, strays, loonies and chancers (your Stockys and "Adolf Hitlers") who flocked to, and in some cases actually lived in 3 Savile Row at the height of the Apple era. However, there are exceptions; the following conference room looks much the same in 2009 as it did in June 1968, when it was the venue for a couple of the earliest interior Apple building photos; John, Yoko, Paul, Derek et al lounge on the floor, pre-furniture, and pre-"fear":
