Glistening in the sun, the colourful house is made up of thousands of rainbow glass stones, marbles, shining coins and other metallic trinkets.
Photographer Patrick Pleul visited the unique home in June 2017 to reveal the hidden secrets behind its walls.
Steffen has baptised his masterpiece Schloss Lilllliput, and it stands in the small village of Naundorf, Brandenburg, 100 kilometres south of Berlin.
The four L’s in the centre of Lilllliput are no typo, as they stand for love, lust, humour and passion - all of which begin with 'L' in German.
For over seven years Steffen has been building and shaping his dream home and it now contains many towers and columns, romantic archways and hidden seats.
In this mish-mash of decoration, no two things are the same, and even the windows are different shapes and sizes.
Over two million items lie on and around Steffen’s house, and it has been reported the artist has invested around 100,000 euros into his creative abode.
