House Extension Architect

Architect Partnership for Start-to-Finish Excellence: Keith Henderson

When you choose Muirfield Construction, you don’t just get a builder — you get the power of a trusted partnership between master craftsmen and one of the region’s most respected architects, Keith Henderson. Keith’s designs aren’t just about adding space; they’re about creating spaces you’ll love living in for years to come.

By involving him right from the start, we ensure your extension is perfectly tailored to your lifestyle, maximises natural light, and blends seamlessly with your existing home. You’re not just investing in extra square metres — you’re investing in a design that works beautifully every single day.

What makes this partnership so powerful is the way our build team and Keith’s design expertise come together as one. There’s no back-and-forth miscommunication, no compromises in quality, and no surprises halfway through — just a smooth, efficient process where every detail has already been considered and agreed.

This level of start-to-finish alignment is rare in our industry, and it’s why our clients consistently tell us the process was far easier than they expected, and the result far exceeded their hopes.
