“Happy Building were fantastic to work with. The staff are extremely helpful. They explained everything I needed to know about getting drawings completed and submitted for approval.”  - Jake, Cheam

Passion and belief sit at the heart of the Happy Building team. Every architect and designer works with a sense of duty and responsibility. It’s something much more significant than the ability to create great concepts. For us, it’s about expanding your vision, showing you what’s truly possible, and helping you become part of our family.



Our client design portal is packed with valuable features to help you manage your project in real-time. A single login gives you access to essential documents, files, and daily logs. You can schedule meetings with ease. And also communicate directly with the team using the built-in messaging app.

1. Design

Where the spark ignites! First, arrange a meeting with one of our qualified designers to discuss your ideas. We’ll carry out a quick survey before getting creative. Then, we’ll design two concepts to illustrate the full potential of your project. All within three weeks.

2. Cost Feasibility

Why two design options? Because creative variation often adds value while costing less to build. So we carry out a feasibility study to provide a guide on build cost for both designs. That way, you have the freedom to choose the option that best balances excitement, practicality, and cost.

3. Planning

You have your designs. And you have a view on the potential build costs for each option. Now, we’ll look after the planning process if you like? We’ll manage the submissions and deliver up to two revisions to the planning proposal if needed. So you’ll sleep better at night.
