Concrete With Quiet Confidence
Some buildings try very hard to impress you.
No.1 New Park Square never needed to.
It carries a quiet confidence about it. Calm. Ordered. Understated. Entirely appropriate for Edinburgh in many ways. But beneath that restraint, there was still a certain swagger to the building. An Edinburgh hardman with a structural clarity. A confidence in its own materiality.
From the outset, the client Parabola, never intended this to be a building where the structure disappeared behind layers of finishes, suspended ceilings and architectural smoke and mirrors. The frame itself was intended to shape the character of the architecture. Concrete slabs, columns and edges were designed to be seen, understood and celebrated.
Which, truthfully, is both exciting and mildly terrifying as a structural engineer.
Because once the structure becomes the finish, there is nowhere to hide. Every line matters. Every joint matters. Every pour sequence matters. The building records every decision you make, good or bad, and it does so permanently.
That honesty became one of the defining ideas behind the project.
Working alongside Parabola and Architects AHMM, the ambition was to create a building that felt robust yet elegant. Civic but not pompous. Contemporary without becoming fashionable for the sake of it.
At a time when so many commercial buildings are driven by short-term value engineering and lightweight specification, New Park Square pushed gently in the opposite direction. It embraced permanence, depth and structural honesty.
And concrete, for all its contradictions, remains one of the few materials capable of delivering that feeling properly.
Concrete Tells the Truth
Exposed concrete is brutally honest.
It records every rushed decision, every poor alignment, every lazy coordination issue and every compromise. Once it is poured, that’s your lot.
There is no ceiling hiding the mistakes. No cladding package arriving later to tidy things up. The structure has to carry both the buildingand the architectural ambition simultaneously.
That changes the role of the engineer completely.
You stop thinking purely about load paths and begin thinkingabout rhythm, texture, shadow and proportion. A slab edge stops being merely structural. It becomes part of the building’s identity.
Some of the coordination became almost obsessive. Tie-holepatterns. Pour lines. Joint geometry. Rebar rationalisation. Formwork layouts. We probably spent an unhealthy amount of time discussing 10 millimetres here and there while others in the room quietly wondered if we had all completely lost the plot.
But exposed concrete rewards obsession.
The irony is that buildings which appear simplest are often the hardest to deliver. Simplicity in architecture is usually built up on extraordinary discipline behind the scenes.
And that was the case with No.1 New Park Square.
The Myth of Simplicity
Good buildings often look inevitable once they are finished. As if they could only ever have been designed one way.
The reality is usually organised chaos.
Hundreds of coordination decisions. Endless workshops. Engineers debating movement joints while architects fight for cleaner lines and contractors quietly question whether the entire team needs therapy.
That process is rarely glamorous. But it matters.
At New Park Square, every visible interface required alignment between structure, architecture, services and constructionmethodology. Nothing worked in isolation.
The exposed soffits meant services had to move beneath raised floors rather than overhead. That single decision unlocked deeper daylight penetration across the floorplate while allowing the concrete frameitself to contribute to the environmental strategy through thermal mass.
At slab edges, deep brick reveals and integrated support channels allowed the façade to achieve depth and shadow without compromising structural clarity. Upstands were carefully incorporated to manage solar gainwhile maintaining the quality of natural light entering the building.
Even the structural grid carried architectural intent. The simple 9m × 9m arrangement provided flexibility and clarity while naturallysubdividing into efficient commercial planning modules. The off-centre reinforced concrete core created a distinctive C-shaped floorplate responding directly to the wider masterplan and surrounding urban context.
Simple on paper perhaps. Considerably less simple in reality.
A Building Designed to Last
Perhaps that is where our Scottish perspective subtly influenced the project.
Scotland teaches you to appreciate buildings with honesty and robustness. Buildings with weight. We have a harsh wet climate and require buildings that weather properly. Buildings that wear in rather than wear out.
Bringing that mindset into Edinburgh, a city often defined by civic restraint, proportion and elegance, created an interesting balance at New Park Square.
Too much modern construction feels temporary. Thin façades. Lightweight finishes. Buildings designed around short-term spreadsheets rather than long-term civic value. Entire developments already feeling tired beforethe scaffold is even down.
New Park Square resisted that instinct.
The building embraced permanence. Thermal mass. Daylight. Material depth. Structural expression. The decision to expose the concrete soffits removed the need for extensive suspended ceiling systems while allowing the frame itself to shape the atmosphere of the spaces.
In sustainability terms, that approach carries genuinevalue. Not simply because of operational performance, but because durablebuildings tend to remain loved for longer. And buildings that remain loved tendto survive.
Perhaps that is the real sustainability challenge facingcities now. Not just reducing carbon, but creating buildings people still careabout in fifty years.
Boutique Engineering Means Giving a Toss
At Woolgar Hunter, we often talk about “boutiqueengineering.”
Truthfully, it just means caring more than people expect you to.
It means refusing to treat projects like products on aconveyor belt. Every building deserves its own response. Its own structurallanguage. Its own personality.
At No.1 New Park Square, that mindset shaped everything fromslab optimisation studies through to the detailing of visible interfaces.
Multiple slab configurations were tested iteratively, 300mm, 310mm and 325mm arrangements with varying upstand geometries, balancingstructural efficiency, embodied carbon, long-term deflection and architecturalambition simultaneously.
And because the soffit remained permanently exposed,long-term movement became critically important. A visible crack or slightdeviation might seem insignificant in a conventional office hidden behindfinishes. Here, it became part of the architecture itself.
Maintaining a consistent 10mm brick joint while controllinglong-term deflection to within approximately 5mm required extraordinarycoordination between structural and architectural detailing.
Some people probably thought we were overthinking it.
They were probably right.
But those are often the details that separate buildings withgenuine quality from buildings that merely function.
Site Is Where Theory Meets Reality
Drawings are one thing. Site is another.
Exposed concrete projects live or die during construction.
You can produce the fanciest digital model in the world, butif the formwork drifts, the curing process is rushed or the compaction andsequencing is poorly controlled, the building will absolutely grass you in.
Good concrete requires discipline from everybody involved. Engineers. Architects. Contractors. Joiners. Site managers. Suppliers. Everybody.
This project demanded constant involvement throughoutconstruction, not simply periodic inspection. Site became part design studio, part problem-solving exercise and occasionally part group counselling session.
Visual concrete is not something you check at the end. It iscurated continuously throughout the process.
Pour sequencing was reviewed for visual rhythm as much asstructural behaviour. Bespoke concrete mixes were developed to maintain consistency in tone and finish. Edge details were refined repeatedly. Reinforcement layouts were rationalised to support both performance and buildability.
That level of care only works when the entire team genuinely buys into the ambition collectively.
And to their credit, they did.
Engineering as Civic Practice
Structural engineers are often taught to stay in their lane. Solve the problem. Run the numbers. Keep the building standing.
But projects like No.1 New Park Square remind you thatengineering is also cultural.
The structure shapes how people experience space, whetherthey consciously realise it or not. It influences light, proportion, comfort, atmosphere and permanence. It affects how a city feels.
That is why engineering should never be reduced to a background technical service.
At its best, structural engineering becomes part of the civic identity of a place.
Ultimately, No.1 New Park Square reflects the kind of engineering we believe cities increasingly need, honest, durable, environmentally conscious and architecturally confident.
A building shaped through collaboration between Edinburgh restraint and a slightly more hard-headed west coast approach to structure, material and construction.
Quietly confident.
And hopefully built to last.
