Extension Villa Heuvelrug Adds Space to Dutch 1970s Bungalow

Located in Maarn, Netherlands, the Extension Villa Heuvelrug was renovated by Bloot Architecture in 2024. The project reimagines a 1970s house, aligning with its original character. The addition features a two-storey extension, creating seamless transitions between the living space and the garden.

Bloot Architecture Adds Two-Storey Extension

Dutch architect Gerard Terschegget from Bloot Architecture has added a two-storey extension to a villa on the edge of the Utrechtse Heuvelrug national park in the Netherlands.

According to the studio, the house was originally built as a bungalow in the 1970s but added more space and dormer windows in a renovation that took place in the 1980s.

Modern open-plan living space with wooden beams, glass walls, and a glass coffee table.

With its latest renovation, Terschegget added a two-storey gabled extension to the side of the home, which he believes provides a “better relationship” with the garden.

“The contrast between old and new is subtle,” he said.

“By joining the extension in the middle of the house, the seating area can be moved in its entirety to the extension and the limited relationship from the living room to the garden has changed into an almost limitless transition between the living room and the garden.”

Demarcation Between Old and New

The ground floor of the new addition is set back from the gable roof above, intended to create a demarcation between the lower and upper floors.

Bloot Architecture constructed its new ground-floor living room almost entirely from glass, which has been set back beneath the extension’s upper level to create a rooftop viewing area.

Expansive glass walls, wood beams, and a cozy winter scene outside create a serene interior.

“The steel construction in combination with the minimalist detailing ensures that the gable roof hangs floating above the new living room,” Terschegget explained. “This means that the entire extension on the ground floor can be made of glass and there is an optimal relationship with the garden.”

Expansive glass walls, wooden beams, and cozy seating create a warm, modern space.

Inside the new living room, Bloot Architecture added a low wall for privacy, which doubles as storage space. The whole design was clad externally in wooden cladding, hoped to create continuity across the new and old parts of the home.

“The materialization fits in with the existing villa in its entirety,” said Terschegget. “The zinc edging with a hidden gutter, the tiled roof, a wooden infill at the end and the cobbled brick façade can all be found in the existing house.”

The first floor of the extension contains a main bedroom, illuminated by skylights.

“The new gable roof has created space for a spacious new bedroom with large skylights for lots of light and air,” Terschegget said.
