Classic collides with contemporary and historic meets modern under the roof of one unbelievably cool townhouse property – part infill project, part retrofit, part adaptive reuse, this is a dream space with secret rooms for people who love cozy remodeled lofts and private luxury interiors all at the same time.

Beneath pealing paint and crumbling red bricks on the front of his history row-house facade lies an incredible residence, reinforced with stunning steel supports and remodeled inside and out with modern materials, furniture and fixtures.

A movable glass enclosure creates a pleasantly-ambiguous indoor-and-outdoor area that bridges the open gap in the (elongated and narrow) plan from front to back, resulting in something that works as an exterior garden or interior greenhouse.

New wood shelving stretches from wall to wall in the renovated structure while metal bookcases and staircases line the spaces and pierce from one room to the next.

Exposed wood beams and rafters, worn red brick and metal pipe railings manage to combine a sense of coziness and warmth with an overall mixed-industrial, somewhat harsh and cold aesthetic.

Bedroom, bathroom and kitchen all contain a strange combination of old and new – raw and rustic furnishings and bare-bone fixtures alongside the latest appliances and clean contemporary additions to otherwise retro areas.

Photographed by Dujardin Filip, House 43 may be have one of the most impressive interiors ever created within an unassuming and humble townhouse shell – a series of rooms that mix old and new in ways that are both clever and classy, appealing to architecture lovers of all kinds.
