A Renovated Double A-Frame Cabin Gives Nod to Its 1970s Past

Nestled amid the serene woodlands of Lake Arrowhead, California, the Arrowhead Double A-Frame House – also known as “Bern Double-A” – is an artful transformation of a 1970s cabin. Designed by Dan Brunn Architecture (DBA), this structure elegantly melds the nostalgia of vintage architecture with modern aesthetics, offering a unique retreat that balances luxury with eco-consciousness.

The renovation re-envisions the original A-frame as a “double A-frame,” a novel approach that combines the firm’s distinctive minimalist aesthetic with warm, inviting elements. The cabin’s original T-shaped footprint proved ideal for expanding the A-frame structure in two perpendicular directions, creating a dynamic geometry that feels both familiar and bold. Central to this renovation is the addition of a glass wall on the short axis of the structure, a feature that allows ample light into the lofted areas and visually connects the indoors to the forested landscape beyond.

Inside, DBA’s characteristic restraint in material selection is clear, ensuring an effortlessly timeless feel. Existing woodwork, including the cabin’s original beams and ceilings, was meticulously restored through a unique sandblasting process with walnut shells, preserving the wood’s natural texture while harmonizing with new floors. This thoughtful treatment emphasizes the continuity between the cabin’s past and its revitalized design.

The living room serves as the focal point of the home, where a tall, glass-framed A-frame ceiling contrasts with a rustic fireplace clad in tumbled stone. Designed for relaxation and connection, this space offers sweeping forest views and a cozy semicircular sofa centered around the hearth. Hidden cove lighting enhances the ambiance by casting a warm, inviting glow across the vaulted ceilings, further enhancing the cabin’s connection to nature.

The design unfolds across three levels, each carefully orchestrated to suit distinct functions. The ground floor provides a tranquil zone for bedrooms and utilities, while the second floor brings a social, open layout that includes a guest suite, living and dining spaces, and a kitchen that flows seamlessly into the surrounding scenery. The third floor, an airy loft, features high ceilings, cozy carpeted floors, and mid-century-inspired furniture, adding an element of playful sophistication. Floor-to-ceiling windows strategically placed throughout amplify views of the surrounding woods, inviting nature to become an integral part of the interior experience.

A soft, dark navy hue – featured prominently in the cabin’s core elements, cabinetry, and select exterior areas – creates contrast against the lighter woods of the bedrooms and living spaces. This choice imbues the cabin with a grounded elegance, echoed by navy exterior siding and decks. The kitchen thoughtfully reflects 1970s design inspiration with dual-toned cabinetry and intricate details, including slim, dark-framed edges and custom wooden pulls. White, soft-touch Fenix laminate blends with dark blue-gray finishes, achieving a modern yet period-authentic feel.

Up in the loft, oversized windows provide unobstructed views of the treetops, reinforcing the cabin’s integration with the landscape. Here, bespoke built-in cabinetry displays vintage records and a turntable, celebrating the cabin’s mid-century charm. Adding a touch of whimsy, a Noguchi Akari lantern placed in the corner, illuminates the space in soft light.

The sleeping areas are designed as intimate retreats, each outfitted with Scandinavian-inspired decor, plush rugs, and soft fabrics. The main bedroom is particularly striking with its vintage-inspired reading nook accented in Irish Green, matched with a plush velvet sofa, creating an inviting spot to unwind. Thoughtful lighting fixtures, including wall sconces and floor lamps, add a gentle, ambient glow that enhances the overall sense of calm.

Sustainability is at the heart of DBA’s approach. The renovation focused on minimizing waste, retaining as much of the existing structure as possible, and reducing the need for new materials. Upgraded insulation, energy-efficient windows, a high-performance heat pump, and LED lighting all contribute to the home’s energy-conscious design. By preserving the existing exterior and implementing sustainable upgrades, the Arrowhead Double A-Frame achieves a balance between environmental responsibility and luxurious comfort.

  • Messner: A childhood dream comes true

    At the foot of the Sciliar, in the picturesque area of Alpe di Siusi (Bolzano), the spirit
    of a barn is reborn as a home. The project, realised by noa* (network of architecture), has
    at its core, the South Tyrolean tradition combined with surprising features internally,
    resulting from design of visionary and unexpected spaces. An almost magical ambience is
    created, inspired by childhood memories. Keep tradition in mind, but at the same time move away so as to create an original
    identity, a new way of living, a different structuring of the domestic space, and to search
    inspiration from a childhood passed in the mountains. This, in summary, was the challenge
    faced by noa* in the project to construct a new home at Siusi in Sciliar, a construction to
    take the place of a deserted house in the centre of the village, with the original
    structure dating back to 1850. The job, completed in 2017, needs to be understood in its complex and delicate context. We
    are talking about South Tyrol, and a project executed at a height of 1100 a.s.l. at the
    foot of Alpe di Siusi, a part of the Dolomites recognised as a Unesco World Heritage due to
    its outstanding natural beauty. It was therefore extremely important to respect the
    parameters of the original structure and the urban planning requirements and regulations of
    the village. For Stefan Rier, founder, together with Lukas Rungger of the noa* studio, and
    in this instance ‘his own client’, the project was an opportunity to give a personal
    footprint to his own property. In this sense there was a move away from the traditional
    principles of spatial distribution, this being achieved in part by recalling memories of a
    childhood spent in the mountains. “We wanted the project to respect the aesthetics and the urban aspects of the village, a
    village where wooden barns alternate with plaster-fronted houses destined for farmers and
    the keeping of cattle.”, explains architect Rier. “With this in mind, we finished the
    exterior structure with a ‘coating’ in keeping with tradition: a wooden grid on all 4
    sides, just as is used for alpine barns. However, as far as the interior is concerned, I
    decided to leave tradition behind me, and thereby free the design from any preconceived
    limitations. In this way I was able to look forward…but also a little back in time to the
    beautiful years of my childhood”. The outcome of the project is a dwelling, having two aspects which confront each other in
    their style. The exterior represents the traditional alpine location, splendidly immersed
    in the local topography, whilst the interior boasts the visionary impulse, the surprise of
    a space freed from the general scheme of things, almost permeable, osmotic, and certainly
    innovative. On the ground floor there is a common area which spreads out almost in a ‘piazza’ fashion
    for (habitational)and interactional use: there is a dining table to enjoy with friends, an
    ample sized kitchen to accommodate more than one cook! The rest of the house develops in a
    vertical way and instead of the classical room division there are what can be described as
    ‘hanging boxes’, which are positioned at different heights and interconnected by stairs and
    walkways – they giving the sensation of walking up a mountain path towards the peak. The
    hallways are carefully designed so that, apart from their connecting function, they
    accommodate other essential areas such as the library and open ‘bathroom’ areas with tubs
    and showers (only the WC are closed in). The entire structure is conceived in a way that
    the further one goes up the level of privacy and intimacy is heightened. The highest ‘box’
    which features a sauna opens out to the splendid view of the Santner mountain. The revolutionary distribution of the interior spaces can be noted also from the exterior,
    and a sort of counterpoint is created with the traditional presentation of the exterior
    itself. To the north the two boxes of the bedrooms, finished in bronze, can be seen behind
    the wooden trellis shell, and as a result the material contrast is evident, while to the
    south it is sauna box which protrudes the glass facade. It is an architectural concept, both extremely innovative and courageous in nature, but
    which also has the value of being able to evoke an atmosphere of time past. Viewing the
    structure from a distance, the larch framework which supports the hanging boxes with its
    roof supported by 12 metre high wooden columns, seems to be the outline of an old barn. “Thinking about it, I spent a lot of my childhood playing in barns”, underlines Stefan
    Rier, “and one of my lasting and favourite memories is of when I used to climb high up in
    the barns and then throw myself down into the hay. Maybe if I had not had that experience,
    I would never have come to design this house …”. THE STRUCTURE: A DIALOGUE BETWEEN TIME PAST AND TIME PRESENT
    The house mirrors the construction type of the location’s rural buildings. On the stone
    foundation (10x8m), is a wooden structure in larch on three levels, and which supports the
    gable roof, typical of the village’s dwellings. A wooden trellis covers the whole house in
    a shell-like manner, screening the light and heat of the sun in the hotter periods, and as
    a whole it is suggestive of the typical structures of alpine barns. Two boxes, one in
    bronze and one a glass structure ‘peak out’ from the trellis, to the north and south
    respectively, and so revealing to the exterior that there is something complex to the
    interior layout. To the south there is a glass facade and a terrace which opens out to the
    magnificent view over the landscape of the Dolomites, a view which is dominated by the
    splendid sight of the Sciliar massif. THE INTERIOR SPACES: A STATIC CHALLENGE
    Inside the house, the distribution of spaces and functions is really unusual. The ‘boxes’
    which house the three bedrooms are supported by the wooden beam structure, visible in its
    totality (12 metres high). The bedrooms are designed as micro-homes, each one having its
    own particular design, these boxes seem to almost ‘hang’ in the ample volume of the
    interior (1,100 cubic metres). One gains access via a staircase and a walkway system, which
    as well as having a connecting function, accommodate the ‘bathroom’ areas with tubs and
    showers (only the WC are closed in). On the last floor, a box plays host to the sauna with
    a panoramic view, extending out of the southern front. Preceding the sauna, there is a
    book-lounge with an antique majolica stove, which has been taken from the pre-existing
    building. The library together with a cloakroom area complete the private spaces on the
    higher levels.
    The ground floor is a large open space with three diverse ‘island’ functions: the
    relaxation area, the dining area, and the kitchen, resolved with a large working surface
    feature in natural brass, and decorated on the sides with artisan earthenware tiles. MATERIALS
    As well as incorporating materials having a local tradition – wood and stone – the project
    introduces others of a more contemporary nature, in some cases recalling a Mediterranean
    style. The floor resin, giving uniformity to the ground floor appearance, alternates
    between baked clay and sea-blue tiles, the same as used for the side covering of the
    kitchen’s work surface. The brass gives brilliant warm tones to the furniture details and
    to the work surface which also incorporates the cooking essentials and sink. The staircase,
    in finely worked steel recalls the grates of Arabian tradition, creating a chiaroscuro
    effect which is extremely unusual for the Alpine environment. Furniture and Cloth
    The furniture has all been produced to design specification, adhering to a zero-kilometre
    regime. Attention to detail has been scrupulous, as has the search for original solutions
    from both a formal and functional stance. Cloth chosen plays an intricate game with wood in creating an atmosphere almost theatrical
    in kind. Flowing blue drapes act almost as stage curtains in enclosing various spaces and
    giving different and new perspectives. There has also been a coming together of texture and
    décor for the box-like bedrooms, this evident even in the wallpaper in blue tones, and so
    creating a functional soundproofing barrier. Light
    The project strives to make the most of natural light: to the south the facade is a
    complete glass construction, the light being filtered by the external wooden grid
    positioned at 2.5 metres from the principal structure, whilst the jutting out roof shades
    protect the interior from the extreme heat of the summer months. On the roof, a skylight
    opens to the east providing another source of light. To the north there are windows.
    As for internal lighting, in the very high living area, there are suspension lights to
    guarantee sufficient light and in particular for the specific functional areas (dining and
    kitchen areas). Many of the lamps in the house have been design created.
