Substantial Flintshire House extension in Mold, North Wales



The existing dwelling house, in Mold, has had a number of unsympathetic amendments, was quite tired in appearance and required some major renovation. The proposals sought to remodel both internally and externally, rationalising the existing accommodation as well as improving the environmental performance of the house.

The proposals sought to rationalise the internal layout, providing for an appropriate main entrance and family room, and combined with a small contemporary kitchen extension to the rear, which provides a balcony to the reconfigured master bedroom above.

The client was very keen to make substantial improvements both to the passive and active environmental aspects of the house. The proposals include upgrading the insulation to the entire property, including floor, walls, windows and roof. Renewable technologies are also to be added to the house including solar hot water and electricity generating (PV cell) panels to the south facing roof, as well as a ground source heating system.

Ultimately, the renovation and improvements works had a significant effect on the energy efficiency of the house. The existing house had an EPC rating of 46 (E rated). The completed house had an EPC rating of 74 (C Rated). This equated to a CO2 reduction of over 60% from the existing house, even though the house had been extended and the original annex building had no energy improvement works.

With regards to BREEAM Domestic Refurbishment Scheme the project effectively achieved a BREEAM Excellent level with regards to the Energy Efficiency (EER Post Refurbishment) as well as achieving over 90% of the credits for the Primary Energy Demand and 60% of the credits for the improvement in the Energy Efficiency Rating.
