What Is Microsoft Building 40?

Building 40 is located on Microsoft’s main campus in Redmond, Washington. It’s where some of the company’s best minds work together to create the future. It’s home to many engineering, research, and project teams, including the famous Microsoft Research division.

This building isn’t just a pretty place to work. It’s a blend of tech, nature, art, and collaboration. When people say “innovation,” this place lives it every day.

Why It’s So Cool

So why should anyone care about an office building? Because Building 40 is designed to be a playground for smart ideas. Let’s look at some of its best features:

  • Smart sensors that track temperature, lighting, and human movement to reduce energy use.
  • Collaborative spaces with writable walls, flexible seating, and creative zones.
  • Indoor gardens to improve air quality and promote calmness.
  • Open access to technology like VR headsets, Surface Hubs, and 3D printers.

You could say it’s half lab, half lounge, all awesome.

Where Magic Happens – Inside the Labs

Microsoft is serious about research. In Building 40, there’s a buzzing energy in the labs. Engineers, designers, and scientists work side by side. They test new products, build prototypes, and explore far-out ideas.

Some famous projects started here:

  • Cortana – Microsoft’s virtual assistant.
  • HoloLens – A mixed reality headset that lets you interact with 3D worlds.
  • Surface devices – Those sleek hybrid laptops and tablets.
  • AI platforms – Like the Azure AI tools used around the world.

Building 40 encourages people to test crazy ideas and see where they lead. Some ideas grow into global products. Others teach valuable lessons along the way.

Design That Encourages Innovation

This place was built with intention. The layout makes it easy to bump into someone smart and share a lightbulb moment. It’s all about chance collaboration.

Key design innovations include:

  • Hallways that curve and twist to slow you down and start conversations.
  • Breakout spaces with cozy furniture for informal chats.

The entire building feels like a meeting of nature and technology. It’s beautiful and functional.

Focus on Sustainability

Microsoft takes the environment seriously. Building 40 is part of their push for sustainability. That means less waste, smarter use of resources, and planet-friendly choices.

Here’s what they’ve built into the space:

  • Low-energy lighting systems based on natural light levels.
  • Reclaimed materials used for furniture and decorations.
  • Smart climate control that reduces energy use by analyzing occupancy and temperature.
  • Water-saving features in restrooms and green plant systems.

The goal? To create a building that’s “alive” — one that responds to the world and people inside it.

Cool Tech Inside

No surprise — this is Microsoft we’re talking about. The tech inside Building 40 is amazing!

  • AI-powered conference rooms that adjust settings based on how many people walk in.
  • Facial recognition entry for staff (optional and secure, of course!).
  • Digital whiteboards to sketch big ideas with a finger swipe.
  • Mixed reality setups where developers build apps in 3D space.

Even the coffee machines are smart — learning who likes what and suggesting preferred drinks.

People First Culture

One secret to innovation? Happy teams. Building 40 is designed to promote wellness and connection. This isn’t just talk — people here really love coming to work.

Some of the people-friendly features include:

  • On-site cafés with fresh food, including vegan and gluten-free options.
  • Meditation and nap rooms for mental health breaks.

  • Walking paths outside the building for outdoor meetings.

Microsoft believes innovation happens when people feel safe, seen, and valued. Building 40 brings that to life through its design and daily habits.

The Birthplace of Ideas

Around every corner in Building 40, you’ll find reminders that big dreams start small. From sticky notes with bold ideas to prototypes built from cardboard — creativity flows freely here.

Hackathons, brainstorming events, and user testing labs keep the energy fresh. Anyone can pitch an idea. Everyone is encouraged to join in.

This mindset creates what Microsoft calls a “culture of curiosity.” Ask questions. Try things. Break and build again. That’s how change happens.

Visitors Welcome

Microsoft sometimes opens Building 40 to tours. Students, tech pros, and researchers come by to explore. They get to see what cutting-edge work looks like in real life.

The building serves as both a working lab and an inspiration center. It’s not just filled with gadgets. It’s filled with stories — from VR breakthroughs to smarter ways of working.
