Garage Conversions Northern Ireland
Tiercon Construction Ltd delivers expert garage conversions Northern Ireland, transforming underused vehicular spaces into premium, fully insulated, and structurally compliant living areas tailored to your lifestyle.
- Maximising Your Property's Footprint
Converting a cold, damp garage into a comfortable room requires specialised structural modifications.
We focus on upgrading the thermal efficiency and integrity of the original structure, replacing old garage doors with solid masonry walls, and seamlessly matching your home’s existing external brickwork.
Because we handle all core damp-proofing, structural insulation installation, and floor level adjustments directly, we ensure your newly integrated room feels like a natural, warm extension of your main home.
Our
Process
Repurposing your space seamlessly.
We turn cold, underutilised garages into warm, premium living areas, managing all the structural insulation and floor leveling to match your main home perfectly.
Stage 1 - Structural Inspection
We inspect the existing garage slab, walls, and roof structure to check for damp issues and verify how utility lines can safely tie back into your main property's existing infrastructure.
Stage 2 - Wall & Floor Upgrades
We remove the garage door and build a solid, insulated masonry wall that matches your home's external brickwork. We then apply high-grade damp-proof membranes and pour concrete to level the new floor with your main house.
Stage 3 - Thermal Insulation & Services
Our team installs timber studwork, structural thermal insulation, and fire-resistant plasterboard. During this phase, we also drop in all the first-fix electrical wiring and plumbing lines for radiators or underfloor heating.
Stage 4 - Internal Joinery & Handover
We finish the space with precise plaster skimming, skirting boards, internal doors, and electrical faceplates, leaving you with a warm, fully integrated, turnkey room ready to enjoy immediately.
