Northern Ireland's favourite architects

Are you excited about creating a new home for your family from scratch but don't know where to start?

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

Whether it's a dream home or a modern extension, you'll want architects with experience who know how to navigate what can be a complicated process.

And you'll want architects who have glowing 5-star reviews from previous customers.

Most importantly, you'll want architects who listen to you and make your dreams a reality.

Say hello to Robert Gilmour Architects, Northern Ireland's home design and house extension specialists.

What we do

what we do.

We create architectural design with functionality and purpose.

Positive: Professionalism, Responsiveness, Value

We have used Robert Gilmour Architects for our home extension and renovation project and they provide quality, innovative and helpful architectural advice. The best comments we could make is that they work with you to find solutions and have endless patience whilst still keeping cost control as a key feature.

A rising star of the Northern Ireland architects market who maintain an understated presence - 5 stars thoroughly deserved.

Robert designed and project managed our double-height extension in 2019 on a semi-detached house on Haypark Avenue off the Ormeau Road. From start to finish he listened to us, made all the right suggestions (taking into account our budget and family circumstances) and was able to persuade us to make the right decisions - even when we weren't sure. He took all the hassle and strain out of what would otherwise have been a very stressful 6 months.

I can honestly say three years later that the work he has done on hour house (including the now-famous curved landing!) has vastly improved the lives of our family.

I could not recommend him highly enough and happy to talk to any prospective customers to share our experiences and ‘show off’ our wonderful home.

Experience

I worked with Robert Gilmour Architects on the renovation and extension of my house in Belfast. From start to finish the experience was overwhelmingly positive. They brought a highly-creative, problem-solving approach which smoothed the way for everything; design, planning-permission, building control etc. and overseeing a beautiful project with great care and attention to detail. Would not hesitate in recommending them.
