Modern, healthy apartments in city blocks

The history of the house is an interesting one - hit by a bomb during WW2, was rebuild with lower unsymmetrical new roof, not fitting the clear roofline of the neighbors. In 2008 a need for renovation of the old substance inspired the father and son duo to turn the student research into a project. A new, symmetrical roof was planned to match the gables left and right, which also - by introducing a longitudinal glazing along all facade - gave the possibility of raising the ceiling in the apartments below. 
Martin Strobl Jr. being an architect and investor at the same time was a blessing to this project. Full freedom to experiment and implement new ideas resulted in a harmonious, beautiful project showing solutions for a common problem: how to create more apartments in city blocks from the nineteenth century - widespread in all Europe - and design them as modern, healthy living spaces

Plan light, build fast

Creating light-flooded rooms is not easy in a protected area, where dormers cannot be longer than 50% of the length of the house. Luckily a correct daylight distribution was taken under consideration very early in the design process.

Daylight Visualizer showed dark corners and a dark ceiling surface: exactly the opposite of the project goals. Luckily repositioning of the windows and addition of smaller windows close to the gable solved the problems. Those highlights windows are responsible for indirect light in the apartment and for lightening up the ceiling - the most dominant surface in any attic.

A VELUX representative was visiting the office to talk about another project, and as the first plans of the Schillerstrasse were lying on the table, we discussed them too. A 3D model inserted in the Daylight Visualizer tool showed that the corners, as well as the ceiling, were underlit.

Modern reinterpretation of an old typology

A new, private staircase leads up to the light, to the spacious attic apartment. Due to roof form regulations in the old town, only the kitchen has a vertical wall and connection to the balcony. All other rooms are lit and ventilated from above.
The functions were located around the existing shafts and pipes, which resulted in an interesting typology of rooms. The bedrooms are traditional, their proportions remind of the apartments below. In the middle there is a light-flooded bathroom, lighting up the corridor through a transom window. The corridor and walk-through kitchen connect to the open living and dining area, divided into two zones by shafts, reminding of the classic room proportions.
The spruce plywood construction, glazed in translucent white, is visible inside - its fine pattern replacing other wall decoration.
"There is not much wall space for hanging paintings in an attic apartment, anyway" - laughs Strobl - "and both me and my wife like the wood pattern."

"Although all our windows are equipped with intelligent software allowing for automatic ventilation, it's important to me to open the windows consciously, together with my 8-year-old daughter. She should understand that to cross-air the apartment, we need to open a window in her room and kitchen at the same time."

Sharing know-how and inspiration

"VELUX is a long-time partner of our office. Sure, the products are great, but what I really appreciate is a partner to talk to when in doubt about daylight planning - we added the highlights thanks to VELUX analysis."
Mr. Strobl regularly attends conferences on daylight organized by VELUX. "I learn a lot of theory, which is something I would have never done in everyday office work, and get to see a lot of work by others."
He adds: "I love my job, although sometimes it's tough and it drains all energy out of you. On those days, I like to brighten up my mood by looking at and reading about inspiring projects, often in VELUX publications - it's nice to be part of it."
