Carshaulton Road, Donaghadee 

Planning Permission and Building Control Approval granted. Great news that Phase 1 is now complete. Phase 1 was the rear extension to provide a new Utility, Garden Room and Sheltered Patio. Great seeing my drawings turned into reality! It's was a beautiful home already but exceptional after the completion of Phase 1. Next stage is Phase 2, exciting.......


A summary of the Improvements to this dwelling as follows:


Phase 1 - New Utility & Sitting Room

Provided to the rear, linking through the new Utility to a new Sitting room. Sliding doors to access the patio, sheltered under a canopy and large Velux Vario Rooflight.


Phase 2 - New Master Bedroom / Ensuite

Provided on the first floor over the existing garage a new fourth bedroom (Master) with en-suite.

New Line, Dundonald 

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!

Gilnahirk Walk, Belfast 

What a difference this extension and alterations have made to this home. Check out the before and after photos. Planning Permission / Building Control approval granted and extension completed. We made use of the existing garage space to provide a new open-plan Kitchen / Dining / Family Room. A downstairs WC provided in the space where the store was. Upstairs two bedrooms substantially increased in size. Now a superb home, love it.
