What We Do
Structural Alteration Services
Keen Builders carries out the full range of structural alterations — from removing a single wall to opening up an entire floor plan with steel portals and new beams. All work is carried out from engineering drawings and fully documented.
Wall Removal
Remove internal walls to create open-plan living. We assess load-bearing requirements, install temporary propping and carry out the removal safely — with all structural work from engineering drawings.
Steel Beam Installation
LVL and steel beam installation to carry loads over new openings — sized and specified from structural engineering drawings. We handle the beam supply, temporary works and installation.
Portals & Frames
Steel portal frames to create large openings between rooms — ideal for opening kitchens and living areas into a single open-plan space. All from engineering drawings.
Underpinning & Piling
Foundation underpinning and new piling for uplift restraint, settlement remediation or structural strengthening. Carried out from engineering drawings — as in the Ngaio project where full re-piling was required.
Load-Bearing Wall Removal
Removing load-bearing walls requires careful structural assessment and engineered solutions. We carry out the full process — from engineering brief through to completed finishing works.
Open-Plan Reconfiguration
Full layout reconfiguration — combining multiple rooms into open-plan living spaces. We manage the full build including structural works, relocation of services and all finishing.
Real Project — Case Study
Ngaio — Full Structural Renovation
The Ngaio project is a perfect example of what Keen Builders does best. A 1920s railway cottage required full structural remediation — re-piling, new beams, and the removal of 8 metres of load-bearing wall to open the kitchen and lounge into a single large open-plan living space.
How We Work
Our Structural Alteration Process
Site Assessment & Structural Brief
We visit your property, assess the existing structure and prepare a brief for the structural engineer — identifying load paths, foundation conditions and the scope of works required.
Engineering Drawings
A structural engineer produces the drawings and specifications — sizing beams, piles, connections and temporary works. All Keen Builders structural work is carried out from these drawings.
Consent (If Required)
Structural alterations involving load-bearing elements typically require building consent. We assist with the consent application and ensure all documentation is in order before works begin.
Temporary Works & Propping
Before any wall is removed, temporary propping is installed to carry the load — ensuring the structure remains safe throughout the works.
Structural Works
Wall removal, beam installation, portal construction, piling or underpinning — carried out to the engineering drawings with full quality control throughout.
Reinstatement & Finishing
Services are relocated, new linings installed, plastered and painted — leaving a completed space ready for fit-out. Records of Work provided on completion.
