Client goal
Delivering a signature rooftop penthouse build
Northline Penthouse required a refined, high-specification residential build atop an existing 22-storey tower. Our team coordinated structural reinforcement, premium finishes, and uninterrupted access for residents below throughout the construction window.
Summary points:
Reinforced rooftop slab to support extended floor plate
Floor-to-ceiling glazing installed with crane-lift sequencing
Imported stone, hardwood, and custom millwork finishes
Zero disruption to occupied lower floors
The challenge
Reworking active construction without delaying openings
Mid-project tenancy revisions disrupted installed electrical and ventilation routes across connected retail units, forcing major sequencing adjustments while multiple subcontractors remained actively working throughout the constrained construction programme.
Konstra reorganized construction phases strategically, protecting tenant opening deadlines without creating overlapping contractor conflicts or unsafe site conditions.
Site delivery
Phased penthouse delivery
A three-phase delivery plan covered shell strengthening, envelope completion, and interior fit-out. Each phase was signed off on independently to maintain pace and quality assurance.
Milestone hits:
Shell & Structural Works | Month 4: Reinforcement and steel framing complete
Envelope & Glazing | Month 9: Curtain wall and roof systems sealed
Interior Fit-Out | Month 14: Handover with full snag clearance
Final Result
Phased penthouse handover
Coordinated walkthroughs with the client and design team ensured every detail matched the specification before keys were exchanged.
