## Project Overview

The Ascent project is located in the Pape Lake region, designed as an observatory that facilitates human interaction with local wildlife, particularly migratory birds and various other fauna inhabiting the area. The intent is to create a space that promotes ecological observation and appreciation, fostering a respectful relationship between architectural design and the natural environment.

## Spatial Strategy

The design framework emphasizes verticality, inspired by the migratory patterns of birds. The main structure features a hexagonal form, which not only provides a unique visual identity but also functions as a series of elevated pathways and platforms. These elements create distinct observation points at varying heights, encouraging an immersive experience that allows visitors to engage with the landscape from multiple vantage points. Circulation routes, including ramps and stairs, mimic the organic paths of birds, enhancing accessibility while creating a dynamic sensory experience.

## Materiality and Sustainability

The selection of materials for this project underscores its commitment to sustainability and environmental integration. Alder wood, locally sourced to minimize transportation impacts, serves as a primary construction material, complemented by reeds and local stone, which further aligns with ecological principles. Recycled materials are also incorporated to promote a circular economy in construction. This strategic choice not only reduces the structure's carbon footprint but also fosters a symbiotic relationship with the surrounding ecosystem.

The architectural skin features patterns inspired by natural forms, enhancing both aesthetic appeal and structural performance. Open spaces throughout the design facilitate natural light and ventilation, thereby contributing to a comfortable interior environment for visitors.

`

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
