These twin residences in Riga, Latvia, mirror one another exactly, except that one is clad in timber and the other in blackened steel.
The conjoined two-storey homes are collectively named House on Zaru Street and were designed by Latvian architects Open AD.
Two rectangular box-frames surround each house, overhanging to shelter terraces at either end and balconies at the rear.
Recessed glass channels wrap aroundÂ the building to divide it intoÂ quarters, providing entrances, windows and additional balconies.
Both houses contain open-plan living areas on the ground floor and two en-suite bedrooms above.
This is the second house by Open AD featured on Dezeen within a week - see also a house and terrace surrounded by metallic grey beams.
