Smart Buildings 

Smart infrastructures with security at their core

A smart building is more than just a connected one. While the benefits of automation, sustainability and energy efficiency are well understood, the security of these systems is often overlooked or addressed too late. A smart building without security integrated from the start is vulnerable, not just to cyber-attacks, but to physical breaches, system failures and operational disruption.

At CornerStone, we design smart building strategies that put security at the core. Whether your site is a high-profile workplace development, a critical infrastructure facility or a data centre, our approach balances technology, resilience and operational effectiveness.

We believe smart buildings should be designed and delivered to reduce risks and respond intelligently to the changing threat landscape.

How we help

Our security-first smart building design service considers all layers of a modern built environment. We work closely with design teams, developers and estate managers to enable them to attain all the benefits of leading-edge technology, whilst simultaneously embedding security across system architecture, data networks and operational technology.

Whether you're building from the ground up or enhancing an existing asset, our team ensures smart technologies enhance modern environments whilst strengthening rather than compromising security.

Award Winning Security, Cyber and Risk Consulting

Why it Matters

What to Consider?

Smart buildings rely on connected devices and systems to function efficiently and enable new levels of building monitoring and automation. The Internet of Things (IoT) has opened up a new world of device connectivity, but design and implementation standards continue to lag behind. Communication protocols and software applications, as well as product development, have largely focused on innovation and functionality, and security can easily be forgotten. Without integrated security from the outset, products and systems can become vulnerable entry points. Our security first approach ensures that our clients can harness the benefits that smart systems can offer whilst reducing risk and supporting performance requirements, compliance and resilience.

Integrated Security from Day One

Smart buildings can bring together systems like HVAC, lighting, video surveillance, access control, digital signage, public address, printing, vending and occupancy/building usage analytics. Smart apps can offer an enhanced user experience by integrating and automating these and other systems along with business systems, payment apps and facility services. Without a unified, secure-by-design approach, these systems, and the operational technology that controls them, can expose vulnerabilities that can be exploited by a range of potential threat actors.

Reduces Risk of Cyber and Physical Attacks

Smart buildings are digital assets. Poorly configured or unprotected systems can be exploited remotely or locally, leading to unauthorised access, system failure or data loss. 

Supports Business Continuity and Compliance

A secure smart building is a reliable one, capable of delivering an enhanced user experience in a consistent and reliable way. Security-led design reduces the risk of outages, protects critical assets and ensures compliance with standards such as ISO/IEC 27001 and PAS 1192-5.

Enhances Operational Control and Incident Response

With the right design, systems can provide real-time awareness, coordinated incident response and system redundancy, improving resilience and uptime.

Builds Trust and Future Readiness

Whether it is tenants, staff or regulators, confidence in your building’s systems depends on clear demonstrable functionality. A smart building must be able to adapt and scale without introducing risk and vulnerabilities.

Expert Advice for Your Project 

Security-Led Design Planning

We help clients assess risk early and develop Operational and Functional Requirements (O&FR) that guide smart building system design. This enables design teams to focus on smart functionality, safe in the knowledge that physical and cyber threats, protection of critical assets, operational technology and regulatory adherence are all under consideration and being addressed.

Technology and Vendor Assessment

Not all technologies are equal. We assess products and systems for their interoperability, functional, security capabilities, support for standards and ease of integration.

Network and System Architecture

We design secure segmented networks and system architectures that support building performance while limiting access, protecting sensitive data and ensuring robust incident management.

Cyber Physical Threat Modelling

Our approach considers threat methods that span both cyber and physical domains, such as unauthorised access via building systems or malicious use of connected devices.

Documentation and Delivery Support

We produce clear, standards-aligned documentation, including risk assessments, technical specifications and integration plans. We also support through installation and commissioning stages to ensure specified requirements are implemented correctly.

Leverage Our Experience

We work with clients across sectors, from public buildings and corporate headquarters to critical national infrastructures and manufacturing plants, delivering secure smart buildings. Our work spans master planning, technical design and post-occupancy review, ensuring solutions work as intended and can evolve securely over time.


Understanding the interaction between systems, people and physical space is key. Our designs also consider user experience, desired aesthetics and maintenance needs to deliver long term value.

Holistic Approach

CornerStone’s holistic approach aligns physical security, digital infrastructure and operational practices. We draw on deep expertise across disciplines; security engineering, IT, risk and design, to guide projects from initial vision through to live operation.


Every recommendation we make is grounded in real world experience and technical insight, helping clients to manage complexities, stay compliant and protect what matters most.
