Villa with a broad perspective
Light-flooded rooms characterize this exclusive residence on Pohlesee. The villa opens itself to the nearby waterfront with extensive glazing, and a light band over the central stairway admits light to the inside of the house.

Exclusive residence on Pohlesee
With its striking elegance, the modern residence in Wannsee is representative of the tradition of prestigious villas in the south of Berlin, dating from the second half of the 19th century. The winning entry from a small competition for the waterside property integrates the spatial concept of the private property developer into a modified orthogon. Imposing rounded corners and striking recesses in the discreet brick façade are characteristic of the style.

In the preliminary stage the narrow, elongated site at the water’s edge presented a real challenge for the designers. First of all, the massive reinforced concrete construction had to be anchored in the instable peat soil by means of countless concrete piles that only reached solid ground after seven to twelve meters. The spatial programme extended over 320 square meters on two levels: from the music room to the interconnected living areas with open-plan, combined kitchen/living room, including the central stair sculpture with gallery up to the bedrooms and bathrooms.

A light band in the flat roof over the staircase and a skylight dome over the rain shower admit bright daylight to the inside of the villa and open it to the expanse of the sky. On the lake side the flank wall is fully glazed on both levels, including corner windows. Sliding elements and large windows with anodized aluminium reveals, vertically mounted façade panels and the narrow parapet cladding form dark copper-coloured breaks in the impressive brick façade. Recesses and projections create protected zones in front of the foyer and terrace.

Perfectly harmonized, high-quality materials emphasize the representative character of the villa interior. Fine parquet flooring and steps of oak, ceiling-high oak doors and precise inserts, glass balustrades and natural stone for the bathrooms and white plastered walls harmonize to create a consistent visual identity. The external paving and garden of the lakeside property – formally tailored to the villa – were laid out according to plans drawn up by Gnädinger landscape architects. Terraces separated by steel plates perpetuate the façade details on the ground. The house is supplied with geothermal energy. The owner’s wish for a fine property on Pohlesee has been sustainably fulfilled by means of integral planning.

House on the lake with spectacular architectural design

The detached house on Grüner Weg offers an unencumbered view of the lake, elegantly blends in the surroundings and, with its light-flooded rooms, creates a pleasant ambience for its residents. This dream home has become true for a couple; located on the shores of Pohlesee, a lake in the greater Berlin area. Gnädinger Architekten, architects in Berlin, were the perfect partners to design this home, and heroal the ideal partner to supply window, door and curtain wall systems for this outstanding project.

Sophisticated solutions for a special one-family house

So fantastic the location, so competitive were the demands of this site. Reconciling the ideas and requirements of the building owner with the cone-shaped site on the lake not only required excellent architectural planning, but also intelligent system solutions. heroal became the supplier of choice for windows, doors and curtain walls – from the welcoming entrance area to the skylight in the roof, heroal system solutions convinced both the architects and the building owner. Rolf Gnädinger, architect at the managing architect’s office Gnädinger Architekten, summarises the project as follows: “The building owner asked for an elegant architectural style for this special place. We were able to develop our creativity within the given framework and with a focus on the specific requirements – and were rewarded with a wonderful house on Pohlesee.“

Harmonious reception 

The entrance area of the detached house on Grüner Weg already sets the tone for the design of this house. The residents and guests are welcomed through the entrance door system heroal D 72, offering an individual solution for the front door of this one-family house. The front door panel has the same wooden look as the interior works. The anthracite coloured sidelights of the front door allow for plenty of daylight in the hallway of the house. As a standard feature, the entrance door system heroal D 72 offers a high basic security, so that the demands on security of the building owner were easily met.

Design in tune with sustainability

The special architectural language of the house asked for window solutions which seamlessly blend into the elegantly curved shapes. The window system heroal W 72 offers the highest functionality combined with maximum flexibility, which makes it ideally suited for this architecturally demanding building. The special feature: heroal’s window system scores with maximum thermal insulation values and discreet design, thus meeting the demands of the building owner for an aesthetically appealing and energy efficient design. This is because the unique insulating strip geometry makes large window surfaces with filigree face widths possible.
 

 Design, energy efficiency and ease of use united 

On the ground floor, the lifting-sliding door system heroal S 77 HI provides for a free access to the garden and an unencumbered view of the lake on two sides of the open-plan living area. To meet the demands of the building owner, the glass surfaces were to be planned very generously, while at the same time providing for efficient energy consumption values. The lifting-sliding door system heroal S 77 HI meets both requirements: thanks to the perfect sealing technology with four different levels and wind stop for sash and centre joint, the thermal insulation values of this lifting-sliding door system are excellent – while still providing for unobtrusive face widths of the aluminium frames. This system by heroal also stands out for its high ease of use, even for large elements.

Versatile and beautiful 

Created with the curtail wall system heroal C 50 and the window system heroal W 72, the large, floor to ceiling elements on the first floor provide for lots of natural daylight. The thermally insulated curtain wall system heroal C 50 achieves excellent energy values thanks to foam-filled insulators and continuous sealants, while at the same time offering great freedom of design: in the detached house on Grüner Weg, the front facing the lake is L-shaped and perfectly blends into the architectural language of the house.

Furthermore, the curtain wall system by heroal was used to create skylights, which fill the middle of the house, designed as an atrium, with plenty of daylight at all seasons and represent another design highlight of this project.
