It’s just another street in another residential neighborhood of London. From the outside at least, the semidetached house on the right looks like just any other home, set apart by little else than the coat of bright yellow paint covering the walls. The tropical foliage of the large banana tree fighting for space in the front garden temporarily disrupts the uniformity of the identical deciduous trees lining the street, not to mention looking a little out of place beneath the gray British summer skies.
