Marsland Road is now Masrland Close in Southwark (the other street names around it match the 1901 so I'm fairly certain it's the right one). It seems that it's been built across, presumably why it's "close" now instead of "road".
The buildings there look too new to be the same ones as in 1901,although there are flats there and you can see older buildings in an adjoining street (have to love google maps).
I do have them in 1911 in 2 rooms, with 3 children; 2 streets away in Tarver Road - which also looks to be fairly new build now as well.
I remember my 1xG Grandfather's cottage, which was technically 2 rooms. The front (only) door opened into the living room, there was a teeny kitchen under the stairs (sloping ceiling!), a tiny landing at the top of the stairs and their bedroom, the outhouse was down the bottom of the garden and they had a tin bath.
It was lovely for 1XG Grandad on his own and probably quite nice when it was both him and his wife, but I can't imagine that it would have been much fun for a young couple with 3 children.
I also remember how much furniture was crammed into that tiny cottage.
2 chairs, a 2 seat settee, a piano, a box radio, a sideboard, a cabinet/dresser, a low table, a standard lamp... and somehow we all used to fit (Grandma, Granddad, dad and me) when we went to visit 1xG Granddad of an evening
