San Francisco's Glen Park is home to many stunning architectural marvels. The LSarc design team had many challenges facing them with this design. The four-story Randall House was built into a [steep hill](https://www.trendhunter.com/trends/house-in-the-andes) in the San Francisco neighborhood. The architects used terraces and [unique interior staircases](https://www.trendhunter.com/trends/salmon-house) to make the vertical blend as well as the horizontal. A column runs vertically through all four levels of the home, providing a unique architectural aspect and added ventilation. ## Trend Insights (Trend Hunter) - Score: 2.9/10 - Popularity: 50% | Activity: 29% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Why This Trend Is Growing - **Sustainable Design:** Combining eco-friendly materials and modern technology can create sustainable designs for buildings. - **Indoor-outdoor Blending:** Incorporating outdoor space into indoor designs can bring a new aspect to modern architecture. - **Vertical Designs:** Utilizing unique interior staircases and terraces can create a functional and visually stunning vertical design. ### Industries Being Reshaped - **Architecture:** Architects can utilize sustainable materials and unique designs to create innovative and environmentally conscious buildings. - **Construction:** Construction companies can explore how to blend indoor and outdoor design for unique building projects. - **Interior Design:** Interior designers can incorporate outdoor elements and unique interior staircases for a new take on indoor space. ## Related on Trend Hunter - [Balanced Renovated San-Fran Homes](https://www.trendhunter.com/trends/redwood-house.md) - [Sustainable Dynamic Hilltop Buildings](https://www.trendhunter.com/trends/ro54.md) - [Nature-Rooted Family Retreats](https://www.trendhunter.com/trends/haus-am-lagnesberg.md) - [Stepped Hillside Residences](https://www.trendhunter.com/trends/b2a-architects.md) - [Hillside Bay Residences](https://www.trendhunter.com/trends/lagoon-view-residence.md) - [Hillside Embedded Residences](https://www.trendhunter.com/trends/house-in-the-slope.md) - [Adaptive Family Residences](https://www.trendhunter.com/trends/no-ordinary-house.md) - [Slender Alley Dwelling Revivals](https://www.trendhunter.com/trends/brown-house-1.md) - [Living Landscape Homes](https://www.trendhunter.com/trends/hedge-and-arbour-house.md)
