## Project Overview

The Tower of the Hanging Stones focuses on restoring the medieval watchtower known as Forca di Penne, situated in Capestrano, Italy. This site, historically significant for its oversight of vital pathways, offers expansive views of the mountainous landscape and the adjacent sea. The intent of the project is to revitalize both the physical structure and its historical narrative, bridging the past with contemporary architectural practices.

### Material Integration and Historical Context

The material selection is pivotal to the design approach, where a combination of traditional and modern materials is employed to create a cohesive aesthetic. Steel is utilized for the structural framework, providing durability and modernity, while glass elements facilitate unobstructed views, enhancing the experience of the surrounding scenery. Local stone reflects the region's historical building techniques, grounding the design in its geographic context. Additionally, wooden elements are integrated for warmth, and concrete provides foundational stability, ensuring long-term sustainability and structural integrity. This deliberate choice of materials fosters a dialogue between the historical significance of the watchtower and its contemporary reinterpretation.

### Community Engagement and Functionality

The design incorporates features that enhance the relationship between the structure and the surrounding community. A rooftop observation platform transforms the tower's apex into a viewpoint, enabling users to appreciate its historical significance as a lookout point. The interior space is designed for multifunctional use, accommodating gatherings, educational programs, and exhibitions to activate the site as a cultural center. Furthermore, strategic lighting creates a notable ambiance during nighttime, allowing the structure to serve as both a historical landmark and a contemporary attraction. An important design motif, the “Hanging Stones,” reflects the geological features of the area, symbolically linking the tower to its environment and enhancing its cultural relevance.

This project exemplifies a thoughtful balance between restoration and innovation, emphasizing sustainability and community interaction while respecting the historical roots of the tower.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
