Planning Permission for Cardiff Extensions and Beyond

• Feasibility assessments to determine consent requirements.

• Listed building applications for historic properties.

• Building Regulations compliance, including structural safety and insulation standards.

Case Study: Pontcanna Conservation Area Extension

We recently completed a two-storey rear extension on a Grade II-listed Victorian terrace in Pontcanna. The project featured:

• Reclaimed brickwork to match the original facade.

• Passive House-certified insulation reducing heating costs by 30%.

• Rooflight installations for natural light without compromising privacy.
  The project achieved planning approval within 8 weeks and added £100,000+ in property value.
