Computer Systems Design and Integration

Systems that connect every layer of your operation.

Green Pavilion designs, builds, and operates computer systems that unify your data, applications, networks, and devices into one dependable whole. From the first architecture sketch to round-the-clock operations, we keep your technology simple to manage and ready to grow. The result is a quieter, more reliable operation where your team spends time on the business rather than fighting its tools.

Dependable computer systems are not an accident. They are designed layer by layer, integrated with care, and operated with discipline so your data, your applications, and your people stay connected.

Four layers, one dependable system

Every engagement follows a clear architecture. We look at each layer of your technology stack and make sure the whole thing holds together under real pressure. The same layered thinking guides every project, whether you are modernising a single application or rebuilding your entire technology estate.

01

Layer 01 — Data

Every reliable system rests on a foundation of clean, accessible data. We map your data sources, design storage and retrieval patterns, and build pipelines that keep information accurate and available when your teams need it most. Good data design pays for itself the moment your reporting stops being a manual chore and starts being something you trust.

02

Layer 02 — Applications

Applications are where your business meets its users. We build and modernise the software your staff and customers rely on every day, favouring clear interfaces and reliable behaviour over clever shortcuts that break in production.

03

Layer 03 — Integration

Few systems live in isolation. We connect your applications, databases, and third-party tools so information flows without manual copying, duplicate entry, or fragile workarounds that quietly undermine your operations. The best integration is the one you stop noticing because it simply works.

04

Layer 04 — Edge

The edge is where your organisation touches the outside world: branch devices, sensors, kiosks, and remote teams. We design the last mile so it stays fast, secure, and in sync with the rest of your architecture.

04

Operate

We monitor, support, and improve continuously.

What we do

Six core capabilities cover the full life of a modern computer system, from planning through long-term operation. Each one can be engaged on its own or combined into a complete programme, depending on where you need the most help right now.

Systems Architecture

We design the overall structure of your system, choosing the right components, services, and data flows so every part works together and nothing is bolted on as an afterthought.

Application Development

We build web, desktop, and internal applications that are clear to use and straightforward to maintain, with code that your team can understand and extend. We favour dependable, predictable technology that behaves reliably in production over fashionable choices that add risk.

Cloud Integration

We move workloads to the cloud, connect existing systems to cloud services, and tune the result for cost and reliability without locking you into a single vendor. You keep the freedom to change providers as your needs evolve, and we help you avoid the hidden costs that catch teams off guard.

Data Engineering

We build pipelines, warehouses, and reporting layers that turn scattered information into decisions your leadership can trust, with sensible governance built in.

Network and Security

We harden the connections between your people, devices, and data, applying sensible controls that protect you without making daily work harder than it needs to be. Protection should be invisible until it is needed, and then it should be decisive.

Managed Operations

We keep your systems running after launch with monitoring, maintenance, and responsive support, so your team can focus on the business instead of the plumbing.

We provide computer systems design and related services, including systems architecture, application development, cloud integration, data engineering, network and security work, and managed operations. See our Services page for the full picture.
Cost depends on the size and complexity of the system. After a short discovery conversation, we provide a clear, itemised estimate with no hidden fees, so you know what you are paying for before we begin.
Smaller integrations can be delivered in weeks, while full architecture programmes run over several months. We agree a realistic timeline up front and keep you informed at every stage.
Yes. Our managed operations service provides monitoring, maintenance, and responsive support so your system stays dependable long after the initial build is complete.
We apply strong access controls, encryption where appropriate, and careful handling of personal and business information. Our full commitments are set out in our Privacy Policy.
