about Us

about us.

Did you know that the average person spends over 62% of their life at home?

And, when you add in sleep time and our new post-pandemic 'work from home lifestyle, that figure edges closer to 100%.

So, it's only natural that you'll want your home to be as comfortable, functional, spacious, bright, and airy as possible.

Maybe yours is a dream home in the countryside with a big enough garden for a couple of dogs, a safe space for the kids to play and ample parking?

Or maybe you've already got your dream home, but as your family grows, you need more space?

Let the Robert Gilmour Architects team work with you to build a new bespoke home of any style or extend an existing property.

Robert Gilmour Architects designed the extension for our three-bed semi. They bring a wealth of talent, industry insight and experience to the table, and it was clear from the outset we could trust their advice. 

They resolved issues, such as getting light into dark areas, with really beautiful and transformational design solutions. 

Would definitely recommend.

Northern Ireland’s Favourite Architects

Robert Gilmour Architects

Central to Aga and Robert's success is their ability to listen to clients and act in their best interests.

They've built vital long-term relationships with builders, consultants, specialist suppliers, planners, and building control, thanks to their hard-earned reputation.

As a result, Aga and Robert can easily navigate difficult design briefs, tight budgets, awkward site conditions, and stressful planning applications.

I would highly recommend Robert Gilmour Architects. They offer a high quality service, and help you get things done. Knowledge is power…..and Robert has plenty. Great to be able to rely on a professional, efficient and friendly service to non experts like myself.

Your vision and our expertise

A message from Aga and Robert:

"Every project is unique and has its challenges.

Whether it's a new house or an extension and reconfiguration to your existing home, the initial part of our job is to ask enough of the right questions to understand your requirements.

One of the first questions we'll ask you is, "What's wrong or what's not working for you?"

We'll ask questions about how you live and how you want to live so we can design around what's important to you.

We listen and develop proposals to meet your requirements best.

And we'll balance and introduce other influential elements such as; space, light, flow, planning constraints and sensible construction techniques.

We'll then guide you through and simplify what can be a complicated process.

And whether you're the 'hands-on' type who likes to get involved, or you're happy to let us work hard to achieve great results, we'll ensure everything is personalised to your needs."
