The Schmidt-Lademann House[a] is a residential dwelling built 1958 in Floreat, a suburb of Perth, Western Australia.

In contrast to the later more ornamented and playful designs of Iwanoff with some resemblance to Brutalist architecture, the light and clear design of this house is inspired by the Modernist architecture and Bauhaus[citation needed] ideas which Iwanoff was introduced to during his studies and work with Emil Freymuth in Munich, Germany.

[3] The jarrah framed window front on the south side opened a wide view on the Roscommon Reserve[5] directly opposite.

The granite wall extends into the interior as a fireplace in the living area and a barbecue pit on the terrace in the west.

This addition merges very well with the original design especially where it repeats the slanted roof with the external post and beam structure on the eastern end of the home.
