Exploring the Future of Construction: Our experience at REBUILD 2025

From 23 to 25 April, we attended REBUILD 2025, the benchmark event for the digital and sustainable transformation of the building sector, held at IFEMA Madrid. This congress has established itself as a key meeting point to learn about the latest innovations in industrialisation, sustainable construction and artificial intelligence applied to architecture and design. It is the best place to reflect, debating with all the actors involved in the value chain from Design to Construction.

A sector in full transformation

During three days, more than 600 exhibiting companies and 700 experts shared solutions that are shaping the future of construction. At Grup Idea, we attended with the aim of identifying tools and processes that will help us to continue promoting more efficient, sustainable projects that are aligned with the new needs of the market.

One of the most relevant topics of this edition was the incorporation of artificial intelligence (AI) in different phases of the construction process. From architectural design to site management and predictive building maintenance, AI is demonstrating its ability to improve decision-making, reduce errors and optimise resources.

Participation of Grup Idea in the round tables of REBUILD 2025

One of the highlights of REBUILD 2025 for us was the participation of our Director of Design and Marketing, Miquel Àngel Julià Hierro, who moderated four key round tables to understand the future of construction, innovation and the design of spaces:

• Josep Llinàs, Gold Medal for Architecture
  A special meeting that highlighted the career of the architect Josep Llinàs, a benchmark in the world of Spanish architecture, where his vision of the architectural project, the importance of detail and respect for the context were debated.
• Hungry City: Sustainable spaces and systems
  With the participation of architect Pere Joan Revetllat, the round table explored how architecture and construction must adapt to create more sustainable, resilient and environmentally conscious cities, also analysing new models of urban food and the importance of the GYM sector when designing a space.
• Digitising productivity: ERP, BIM and AI
  This session analysed the crucial role of digitalisation in the sector, with a focus on tools such as ERP, BIM and artificial intelligence, which make it possible to increase productivity, optimise construction processes and improve project efficiency.
• Collaborative environments: 3 manufacturers, 3 success stories
  A practical debate where, based on three brands, three real cases of collaboration between manufacturers and architectural projects were presented, demonstrating how working together improves results, boosts innovation and speeds up execution times.

The moderated roundtables brought together experts from different fields -architecture, design, construction, technology, industry and sustainability-, reinforcing Grup Idea’s vision that the transformation of the sector can only come about through transdisciplinary collaboration and a commitment to open and constant innovation.

Key trends at REBUILD 2025

These are some of the thematic axes that most inspired us during our visit:

1. Artificial intelligence and generative design

AI-based generative design solutions make it possible to analyse multiple variables (cost, energy efficiency, materials, etc.) and generate optimal proposals in record time. Tools such as Spacemaker or algorithms integrated in BIM software are revolutionising the way spaces are conceived.

2. Industrialised construction

Prefabrication and modular systems continue to gain ground. Leading companies presented solutions that make it possible to build faster, with less waste and better quality control, thanks to more standardised processes and technologies such as large-format 3D printing.

3. Full digitisation with BIM and Digital Twins

The use of BIM (Building Information Modelling) is consolidating as a pillar of digital transformation. Now, together with Digital Twins, it opens up new possibilities for real-time monitoring and management of buildings, even after handover.

4. Sustainability and circular economy

Decarbonisation of the sector is a priority. From the use of recycled or low footprint materials, to passive HVAC systems or energy positive buildings, the proposals presented at REBUILD show a clear commitment to the environment.

What can we implement now?

We come back from REBUILD with many practical ideas that we can transfer to our projects:

• Integrate AI solutions in the design phase to optimise spaces, flows and energy efficiency.
• Betting on industrialised construction models, especially in retail projects and modular spaces that require speed of execution.
• Deepen the use of collaborative BIM as the axis of coordination between architecture, engineering and construction.
• Incorporate life cycle analysis (LCA) criteria from the start of design to measure the environmental impact of our decisions.

REBUILD 2025 confirms that the future of construction is digital, industrialised and sustainable. At Grup Idea we remain committed to innovation as a tool for designing more efficient, human and environmentally responsible spaces.

We will continue to explore new technologies and share with you our vision of how to transform the construction sector, project by project.
