Ligar Bay Bach: A Modern Jungle Treehouse with Ocean Views

Young Architects have designed a modern holiday home called the Ligar Bay Bach (‘bach‘ is a colloquial term in New Zealand for a small relaxed holiday home), located in the picturesque region of Ligar Bay, Tasman, New Zealand. This innovative project spans 163 square meters and presents a modern take on a jungle treehouse, perfectly suited for both the homeowner’s vacations and rental purposes. Having previous experience with design and construction, the clients provided a detailed request complete with imagery, prompting the architects to push the boundaries. The site posed significant challenges with its steep, unstable landscape, necessitating meticulous planning and design.

The layout of the Ligar Bay Bach encourages a sense of adventure, with movement between spaces resembling a journey through tents in a forest. Utilizing the natural elevation of the site, the stacked, glass-fronted pavilions offer unobstructed views of the coastline and ocean, fulfilling the requirement for separation and privacy.

The design breaks up the building mass through the use of depth, transparency, and reflectance, while the materials – concrete, wood, and steel – are prominently showcased in both structure and finish. These locally sourced materials, including low-carbon Golden Bay cement and plantation-grown wood, contribute to the home’s minimal environmental impact.

Thermal bridging is thoughtfully addressed to reduce heating needs, and passive cooling is met through the use of skylights that function as chimney vents, alongside opening doors to create breezeways.

The top pavilion is divided into two spaces with an open hallway in between, housing the primary bedroom on one side and the main bathroom on the other. The central path is flanked by floor-to-ceiling glass on both sides making it feel as if one is walking outside to access the other space.

The primary bathroom comes with some of the best views, from both the inside and out, with an entire wall that is a window, offering sightlines of the water below. The space includes a sunken bathtub built into the floor.

Flexible in design, the home features a main pavilion with two bedrooms adjacent to the kitchen, living room, and dining room. Future adaptability is built in, with provisions to add another bedroom on the bottom level if needed.

  • Good Haus

    The Good Haus celebrates the intersection between design and performance – and seeks to be an example of a “good house”. The house is the family home of principals Mela Breen and David Good (designer and builder) – and playfully gets it’s moniker from Dave’s last name. So what is our idea of a good house? In this case it is one that is pushing the possibilities of a site specific design while holding itself accountable to reaching the highest level of energy efficiency. Our good house is one that embodies our beliefs about resiliency, efficiency, health and comfort, beauty and playfulness. The DNA for the Good Haus is established by the site, a steep and rocky hillside that spills down onto a small neighboring foothill meadow. A limited buildable footprint, season drainage concerns, and an inviting flat outcrop of granite drove the initial design. Two intersecting geometric volumes were conceived, each reaching out to connect the building to the landscape, each intersecting the other and providing counter balance. The main first floor volume is a long south facing rectangle that stretches and anchors in the granite. A deep west facing porch protects the house from overheating, bridges a rocky drainage and links the open floor plan to the landscape with a large outdoor living space. The second floor volume runs perpendicular to the main living space and cantilevers to create a covered north entry, while a balcony on the south side cantilevers towards the oak canopy – creating a sense that the master bedroom is in a tree house. The exterior material pallet is in keeping with our love for the handmade modern. Cedar siding from trees grown on Mela’s childhood property and milled by her father is mixed with standing seam metal roofing that turns downing to clad the walls as a way to articulate the building form. Because the topography falls roughly 12’ over the relatively narrow width of the house, and the granite spine to the west hinted at what might lay below the soils (giant boulders and bedrock), we opted to build the first floor primarily on a steel pier and beam structure with a metal pan deck. This allows the building to float above the rocky drainage. The complexity of the design, with its cantilevers and steel deck foundation, require a heightened attention to the air sealing and insulation details. The super insulated, air-tight building envelope is wrapped in exterior Rockwool insulation, all the connections between interior and exterior structural members are meticulously detailed to avoid thermal bridges, and triple pane European windows and doors are used to maximize light, comfort, and performance. A CO2 heat pump water heater provides the most efficient domestic hot water delivery. Balanced heat recovery ventilation offers high indoor air quality and uniform temperature distribution. Indoor climate control is provided by super efficient ductless mini splits. A 6.5 kw roof mounted photovoltaic system is installed to offset the home’s energy usage (including the charging of an electric car) – creating a zero net energy building.
