My latest project just completed and wow, we think it's fantastic. What a difference this extension has made to Jac's home. I was very pleased seeing the changes and my drawings turned into reality. I am even more delighted receiving another 5 star review.

"Glenn did the drawings for our kitchen extension and redesign of our downstairs layout, which we have just completed. We are delighted with the end result. Every detail has been thought about and it makes such a difference to how we use the space. He also did all the admin behind submitting the drawings to planning etc which was such a help. I would highly recommend"

Many of my clients ask for my help, wanting an old conservatory replaced. In this case replacing it with a modern, fully functioning Dining area (fully glazed) that would be warm in winter and cool in summer!

Take a look at this two storey extension, way back in 2010 (time flies) On the ground floor my clients wanted a new open-plan kitchen area with a sitting room at one end. On the first floor a fourth double Master Bedroom and the exting Bathroom changed to a Shower Room. A simple little project that gave my clients exactly what they wished for.

Check out this one in Bangor West. Great to work with my clients, helping them to extend their beautiful double bay fronted period home, by the sea. It was time to improve one of Bangor West’s finest homes by taking down their old extension and replacing it with an extension that met their current family needs. Just what they wished for.

Crofton Glen, Holywood

My Client appointed me to help him remove his old two storey red conservatory and replace with a modern glazed Garden Room, open plan to the existing kitchen with a balcony above accessed from the upstairs bedrooms.

In my career of over 35 years I have never seen a conservatory quite like this one, two storey and in pillar box red.

The proposed changes will make a significant improvement to this lovely home by creating a wonderfully spacious open plan family room on the ground floor and a balcony above.

Orby Drive, Belfast

My clients wanted to stay in their home and not have to move but their existing accommodation wasn't meeting their needs. I could understand why, they had superb views over their large gardens towards Greenville Park. All the best views was from the small Patio. The answer was to create a new large open plan Kitchen / Dining / Family space, widen the existing window and install large sliding doors from the new space. Also being added was a downstairs WC and a Study. Such a difference this extension made, what a wonderful new, improved home!

Sandeel Lane, Orlock

This beautiful seaside cottage, clad in charred timber is certainly unique and what a wonderful location overlooking the Irish sea. The goal was to provide a new first floor with open-plan living accommodation and a Master bedroom with Ensuite. The upstairs views will certainly be superb looking out towards Scotland and on a warm day the new balcony will be a treat to use. If ever I buy a unique seaside home this would be the one for me, love it. Great news that planning permission has been granted.
