House Extension projects in Northern Ireland
Tiercon Construction Ltd delivers premier house extension projects in Northern Ireland, managing your build with absolute precision from foundations to final turnkey completion.
- Seamless Structural Additions for Your Home
Adding an extension requires a careful balance of heavy structural engineering and respect for your existing property.
We specialise in managing the complex elements of residential expansions, from precise knock-throughs and steel beam installations to matching architectural features perfectly.
Because we directly control all the foundational groundworks and structural connections ourselves, we ensure your new space connects flawlessly with your original home while meeting modern UK building standards.
Our
Process
Extending your home without the stress.
From structural knock-throughs to matching your existing brickwork, we handle the complex engineering so your daily routine remains as uninterrupted as possible.
Stage 1 - Design & Survey
We review your architectural plans, survey how the new addition ties into your existing structural layout, and verify that all building regulations approvals are firmly in place before any ground is broken.
Stage 2 - Groundworks & Steels
We self-deliver the new foundations and drainage, followed by the installation of temporary propping and heavy structural steel beams to safely create the internal openings into your current home.
Stage 3 - Building the Envelope
Our team builds out the external brickwork, blockwork, and structural roofing. We focus on getting the extension wind and watertight as quickly as possible to completely protect your home from the elements.
Stage 4 - Seamless Integration
We manage the internal transformation, including plastering, plumbing, electrics, and high-end joinery, ensuring the transition between your old space and the new build is entirely flawless.
