Structural concrete
Slipformed cores, post tensioned slabs, and transfer structures poured to survey tolerance rather than to trade convention.
A time lapse of a tower under construction, advancing from excavation and piling through the concrete frame and curtain wall to a completed, lit building. Scroll position controls the sequence.
From excavation to glass,
in one continuous act.
Structural and envelope contracting for high specification towers. One accountable team from groundworks to handover.
Groundworks
Piling, pile caps, and the raft that carries every kilo above it.
Frame
Post tensioned cores and floor plates on a seven day pour cycle.
Envelope
Unitised curtain wall craned and sealed, one floor at a time.
Handover
Balanced, commissioned, tested, lit, and signed over.
The practice
Two disciplines,
one contract.
Most towers are lost in the gap between the frame contractor and the facade contractor. We hold both. The team that sets the slab edge is the team that hangs the panel off it, working to one tolerance and one programme.
Since 2009
2009
Two engineers, one workshop
Kestrel and Haas leave a tier one contractor to build frames the way they had always argued they should be built.
2014
First tower past 100 metres
Anfa Marina proves the pour cycle holds at height. The published programme does not slip a single week.
2019
Facade brought in house
A dedicated unitised glazing factory opens, ending the handoff between the frame trade and the envelope trade for good.
2023
Five countries, one core team
The same forty people now run sites across Europe and North Africa without thinning the standard that started it.
Capabilities
Everything that touches the structure or the weather line.
Five disciplines, self delivered, run off one federated model and one programme.
Curtain wall and facade
Unitised systems engineered in house, mocked up at full height, and pressure tested before a single panel leaves the factory.
Preconstruction
Buildability review, procurement routes, and a cost model that holds its shape once the drawings start moving.
Category A fit out
Risers, ceilings, and floors delivered against the same programme that runs the frame, so the trades never queue.
Commissioning
Seasonal testing, soft landings, and a facilities team that stays on site for the first twelve months of occupation.
Selected work
Five buildings, still standing where we left them.

Method
The same five moves, every time.
No proprietary system, just a sequence we refuse to compress and a weekly report that says out loud where we are against it.
- 01
Survey
Ground investigation, party wall position, and a point cloud of everything we are about to work against.
- 02
Model
One federated model. Structure, envelope, and services resolved before anyone orders steel.
- 03
Pour
Cores lead the plates by two floors. The cycle is published weekly and it does not slip quietly.
- 04
Clad
Panels arrive glazed and sealed. The building becomes weathertight while the frame is still climbing.
- 05
Commission
Systems balanced against the model, then witnessed twice, once in winter and once in summer.

Clients
They gave us the pour cycle on week one and never once asked to move it. That is rarer than it sounds.

We read every brief ourselves. If it is a fit, we book a call within two working days and put a named engineer on it before any drawings move.
