Key factors affecting extension costs in Carrickfergus include the size and design complexity of the project, foundation type and ground conditions, choice of materials (brick, render, windows), and local building regulations compliance. Labour availability and timescale also influence pricing. Single-storey extensions cost less than two-storey work due to reduced structural demands.

Money-Saving Tips
