From the Listing: "Designed by Charles Haertling, one of Colorado’s most celebrated architects, this is not just a home—it’s a rare, livable work of art. Virtually no other Haertling home has undergone a renovation of this caliber, with a reverence for the original design that also maintains a livable, open, and functional floor plan supporting comfort, flow, and purpose. Originally built in 1976, this residence, shaped like twin cones, resembling a cassette tape in plan, is one of Haertling’s most iconic creations. Each tower is anchored by a sculptural, woodburning fireplace. Set against the backdrop of the foothills, the home offers remarkable Flatiron views, sitting like a sculpture in the landscape and blending geometry, nature, and light.

Completely Knocking Down the Original Scottish Stone Cottage Would Have Been Easier

Instead, architecture firm Mallett saw an opportunity to connect past and present by building a new black cabin inside the walls of the ’30s farmhouse.

Houses We Love: Every day we feature a remarkable space submitted by our community of architects, designers, builders, and homeowners. Have one to share? Post it here.

Project Details:

Location: Perthshire, Scotland, United Kingdom

Architect: Mallett / @mallett.uk

Footprint: 2,260 square feet

Structural Engineer: Christie Gillespie Ltd

Photographer: Itago Media

From the Architect: "A stone farmworker’s cottage had stood abandoned and crumbling on this West Perthshire site since the 1930s. Even if it could have been restored, it would have been too small to meet the needs of contemporary family life. From a practical and financial perspective, demolition and a new build made the most sense, but Mallett chose a different path. The studio saw an opportunity to create something extraordinary: an emotionally resonant and highly ergonomic home deeply grounded in the West Perthshire landscape, the local vernacular, and the site’s rural history.

"Rather than demolish the remnants of the cottage, Mallett chose to build a timber-framed structure inside the existing stone shell. This preserved as much of the remaining stone structure as possible, working within its original footprint, while adding a bold contemporary intervention. Influenced by the surrounding mountain views and the pared-back principles of Norwegian ‘hytte’ design, the four-bedroom home strikes a careful balance between past and present, blending vernacular character with contemporary form.

"The blackened larch exterior offers a striking contrast to the pale, timeworn stone of the original structure. Additional stones were painstakingly salvaged, cleaned, sorted by hand, and used for an internal feature wall in the kitchen—a subtle nod to the site’s heritage at the heart of this contemporary interior. On the ground floor, the windows are precisely positioned within the original openings, creating a visual link between old and new. Expansive glazing on the first floor frames views of the snow-capped mountains beyond.

"The project emerged from a collaborative process involving the client, structural engineer, local authority, and a team of skilled craftspeople. This shared effort enabled a careful balance between conservation and innovation, with locally sourced materials and traditional techniques contributing to a result that is both high quality and deeply rooted in its rural context.

"Durable, natural materials anchor the building in its surroundings, while five  gables and blackened larch cladding lend it a bold architectural presence. Inside, a restrained palette of timber, stone, white walls, black accents, and micro-cement flooring defines calm, light-filled spaces that evolve with the shifting daylight. The minimalist approach amplifies the home’s connection with its landscape, allowing texture, light, and views to take precedence. A highly insulated, airtight construction and air-source heat pump will prove energy efficiency and environmental responsibility for decades to come. Black and Stone sets a high bar for retrofit and reuse, showing how thoughtful, site-specific interventions can revive heritage structures—creating beautiful, high-performing homes that honor Scotland’s rural past while looking to the future."

My Search For Furniture I’ll Keep Forever

Here’s where I turn for well-made new pieces that will age gracefully into heirlooms.

Welcome to Someone Buy This!, a monthly shopping column featuring the fun, the frivolous, and the practical from a very discerning shopper.

I’ve been thinking a lot about heirlooms, and what mine might be. The term feels nostalgic, even a bit emotional. It makes me think of antique armoires, fragile china sets, and other things passed down through generations. But what does an heirloom look like today in an era of flat-pack furniture and fast-moving design trends? And what do I own, or aspire to own, that might last long enough to mean something to someone else?

The word heirloom is associated with an old-fashioned and traditional aesthetic. But that doesn’t have to be the case! An Eames chair, for example, is not something you’d describe as traditional but it’s definitely heirloom-worthy. Some heirlooms endure because they’re timeless, others because they’re so specific to their era that they become shorthand for it. Either way, they look intentional decades later. When something is well-made and durable, you’re likely to keep it for a long time. And the longer you have it, the more stories and memories it will hold. Memories and feelings aside, most heirlooms share a few common physical traits. They’re well-built and use materials that age gracefully, like hardwoods, stone, and solid metals. These things don’t deteriorate so much as develop character, and the best ones can be repaired again and again.

The pieces that become heirlooms are the ones we can’t imagine living without and care enough about to fix. So where do you start shopping for your future heirlooms? Here’s where I’ve been looking for my forever pieces.

Roll & Hill

Roll & Hill Lexington Dining Chair

The Lexington series stems from Jason Miller’s interest in American furniture combined with his fascination of Gothic architecture. Inspired by the surprisingly rational structure underlying Gothic buildings when stripped of their ornamental facades, Miller applied that framework to a series of furniture with a distinctly American feel. The latest introduction is the Lexington chair - a dining chair that feels like a hug.

Roll & Hill is one of the first brands that comes to mind when I think about "forever pieces." I have a perpetually open browser tab for the Lexington chair, a piece I return to often. Roll & Hill’s designs manage to feel both vintage and fresh, like something you’ve seen before but never quite this way. 

Sixpenny

Sixpenny Devyn Sofa

Lush, deep-seat comfort with chilled out, modern lines. Devyn’s contemporary shape and breezy slipcover create a unique balance that’s equal parts refined and laid back.


Most new sofas suck. Many have flimsy frames, mystery foam, and fabric that pills if you so much as look at it wrong. Sixpenny’s Devyn sofa is a rare exception. It’s got an actual hardwood frame, not a particleboard skeleton like many of its counterparts, and its slipcovers are fully removable. The brand even offers detailed care guides, making upkeep less of a mystery. It’s a sofa that adapts to how you live now and how you might live later, with pets, kids, or an entirely new space. 

Hetta

Hetta Thicket Dining Chair

With a sculptural frame and generous form, the Thicket Dining Chair brings heft and heritage to the table. Inspired by vintage French designs, it nods to the past while feeling thoroughly present.

Hetta is a new brand from the team behind Sundays Furniture. At their launch party earlier this year, cofounder Noah Morse told me the designs were inspired by pieces from his childhood. You can see that lineage across the collection; the designs are a reimagining of traditional shapes with a playful twist. The Hillside chair, for example, looks like something you’d find in your grandmother’s house—a ladderback chair that stretches up toward the sky. The dining table’s spindle legs give a familiar silhouette a dramatic effect. My favorite piece, the Thicket dining chair, feels both nostalgic and modern, with a chunky, interlocking frame that reminds me a bit of Lincoln Logs. The whole collection strikes a balance between polished and approachable. 

Thuma

Thuma Nest Dresser

Designed to fit any space, the Nest Dresser provides perfect placement for necessities. 100% upcycled wood, thoughtful detailing, and an innovative modular system makes for a lifetime of modern functionality and optionality. Do not stack more than 5 drawers or 47" vertically.

I’m a big Thuma fan, especially their modular pieces. I love furniture that can change with my needs. The brand’s Nest system, which includes drawers and open shelves, has been a fixture in my home for the last few years. Rearranging the pieces is super easy, they simply stack into place. You can use them as nightstands, a dresser, media console, room divider and more.

These Quick Upgrades Made a Big Impact in My Home

Tools You Probably Already Own Were Used to Build This Tiny Prefab Home in Ecuador

El Sindicato Arquitectura designed a panelized 260-square-foot cabin that the owner put together himself using cordless drills and screwdrivers.

Welcome to Prefab Profiles, an ongoing series of interviews with people transforming how we build houses. From prefab tiny houses and modular cabin kits to entire homes ready to ship, their projects represent some of the best ideas in the industry. Do you know a prefab brand that should be on our radar? Get in touch!

In April 2016, a 7.5-magnitude earthquake hit the town of Muisne, 110 miles from Quito, Ecuador, and destroyed an estimated 7,000 structures. In the wake of the devastation, there was a need for easy-to-transport housing that was also easy to assemble, particularly in rural areas. In response, El Sindicato Arquitectura started experimenting with prefabricated housing, and they created a prototype that people could replicate with materials they had nearby.

Since that first foray into prefabrication, the Quit0-based practice has developed a number of like-minded projects, including a tiny home that can be fixed to the rooftop of apartment buildings, a carpentry workshop the studio says is rooted in the principles of prefabrication, and, most recently, a 260-square-foot cabin that adds an accommodation to a family’s farm.

Here, the studio shares more about its prefabrication practice—and the backstories behind some of its most exciting projects thus far.

Located on a rural family farm near Cayambe, Ecuador, this off-grid prefabricated retreat is designed specifically for short stays.

What’s the most exciting project you’ve realized to date?

In terms of projects that are prefabricated, one that has inspired us the most is Casa Parásito, a tiny home that sits on a roof. It challenged many concepts, not only architectural ones, but also philosophical and practical ones, about urban living. It explores how we can take advantage of spaces with great potential that often go unnoticed, and how, by giving a small creative twist to the capitalist system we live in, we can create new, accessible housing options, especially for young people who want to remain living in city centers such as Quito.

Tell us more about Casa Pukará.

Located on the slopes of the Cayambe volcano, in the rural outskirts of the city with the same name, Casa Pukará is part of a roughly 10-acre family-owned plot that has historically been dedicated to livestock grazing, the cultivation of grasses and vegetables, and the artisanal production of cheese. The site already contained basic infrastructure: a country house, a stable, a small dairy, storage buildings, a large irrigation reservoir, and the ruins of a former animal feed storage facility. Casa Pukará introduces a new layer of use over this productive landscape, a sustainable intervention aligned with the vision of Daniel, the son of the family, who wanted to incorporate a low-impact rural lodging experience.

The cabin is intended to help visitors disconnect from the city and immerse themselves, even briefly, in the calm of the countryside. The 260-square-foot plan can accommodate up to four guests in a stepped open-plan layout that uses level changes to define zones.

The entire structure was prefabricated in a workshop using a system of fully finished, demountable panels. The design enabled Daniel to assemble the house alongside his father, using only a basic instruction manual and simple cordless tools such as drills and screwdrivers. This construction strategy addresses the site’s limitations—no electrical power and restricted access that prevents the delivery of a fully built structure.

Dwell Open House 2025: 350 Readers Tour Some of L.A.’s Most Unforgettable Homes

Indoor/outdoor living plays a starring role at these one-of-a-kind residences with immersive gardens.

A 1954 home by Calvin Straub is the centerpiece of a San Marino property developed by Alice Fung and Michael Blatt of Fung + Blatt. Working with the architects, Elysian Landscapes oversaw the design of the gardens.

Showcasing a down-to-the-studs rebuild, a revamped midcentury cabin, and a hillside home with inspired pavilions, Dwell’s second annual Open House: Los Angeles tours on October 18 proved that life in Southern California is like no place else—and the residences we featured all exemplify different ways that a home can engage with the unique landscapes of Los Angeles. The day-long event gave 350 design fans the opportunity to tour some of the city’s most architecturally innovative residences and meet the architects, designers, landscape designers, and homeowners who created them, each embracing the unique conditions of their sites.

Hollyhock House

The crowning jewel of Barnsdall Art Park in East Hollywood, Frank Lloyd Wright’s Hollyhock House was the tour’s starting point. The flowers that gave the house its name (which were client Aline Barnsdall’s favorites) are everywhere—whether abstracted in the home’s furniture, windows, and ornamental frieze or blooming around the grounds. A new native plant garden by the landscape architecture firm Terremoto and an exhibition of Janna Ireland’s photos of the property make it clear that Wright’s design, which was his first Los Angeles commission and the city’s only UNESCO World Heritage Site, remains as vibrant as ever.

Dwell Open House: Los Angeles kicked off at Barnsdall Art Park in East Hollywood, where ticket holders picked up tote bags with route maps and visited the Hollyhock House before heading out to the other three homes.

They Camped Out of a Shipping Container for Years Before Turning It Into a Chic Retreat

The owners expanded the footprint of their Tasmania shelter with cinder blocks, timber finishes, and large panes of glass.

Houses We Love: Every day we feature a remarkable space submitted by our community of architects, designers, builders, and homeowners. Have one to share? Post it here.

Project Details:

Location: Coles Bay, Tasmania, Australia

Architect: Ancher Architecture Office / @ancherarchitectureoffice

Footprint: 1,098 square feet

Builder: East Coast Construction Tas

Structural Engineer: Aldanmark

Photographer: Adam Gibson / @adam.gibson.photo

From the Architect: "For almost a decade our clients camped on their Coles Bay bush block, overlooking the ancient mountain range, the Hazards and abutting the Freycinet National Park. A shipping container provided basic shelter from the elements as they developed their dream for a holiday home. Our addition to this modest settlement is a new small footprint pavilion, which adds much needed amenity to the existing site, yet ensures the built form is humbled by the awe inspiring natural surroundings.

"With sustainability front of mind, our clients were eager to retain the converted shipping container, which housed a makeshift kitchen, laundry, and bathroom and acted as a storage facility. By retaining this structure (including the existing deck area) and focusing on a smaller footprint, we were able to maximize the budget and achieve a higher quality finish. The new addition responds to the existing building in form and material. A key design consideration was to provide our clients with moments of separation and connection from the new and old built forms and their inhabitants. The siting of the new building cradles the existing deck and BBQ area to create a central meeting place.

"Working closely with our engineer, we designed a custom‐made steel and timber batten sliding screen to the side of the new building, offering the clients the opportunity to adjust to the privacy settings to this area. The screen also acts as a sun shading device to the new dining area in the morning. The best view of the mountain is to the south, requiring us to balance maximizing the visual connection with the challenges of passive solar efficiency. This was achieved through carefully considered window placements. There are two large openings in the main living space that provide connection and access to the view. Two smaller windows facilitate access to the midday and afternoon sun. Working with the existing typography of the site, the floor level rises up to the primary suite at the northern end of the building. This creates an intimate scale of space to the private areas of the building and a generous volume over the main living space.

"Natural, raw materials were selected for their robust performance and connection with the surrounding area. The concrete block walls remain deliberately raw inside and out, and have been laid in a stack bond pattern to elevate this standard building material. Timber cladding to the walls and ceiling throughout the house provides warmth to offset the concrete block."
