Construction, architecture and interior under one roof — from the first sketch to the day you get the keys.
Why Rocksolid
Most projects do not fail because someone cannot lay bricks. They fail in the gaps — between the architect and the contractor, between the drawing and the site, between what was promised and what was budgeted. We close those gaps by owning all three.
How we workWhat we do
Design and construction sit under one roof. You deal with one team, not a chain of subcontractors reinterpreting each other.
Solid thinking. Solid details.
One design team carries the building and everything inside it, so the facade, the plan and the fit-out are resolved together instead of negotiated later.
Solid execution.
The team that builds what was drawn. Structure, envelope, finishing and site coordination run by one project coordinator against an agreed scope and programme.
Selected work
Scope, work type and location recorded on every job — so you can see exactly what we did, not just a photograph of it.
Second-phase expansion of the William Booth dormitory in Surabaya, adding accommodation capacity alongside a facility that stayed in use throughout. The work was sequenced so noise, dust and material deliveries were kept clear of occupied areas, and the new structure was tied into the existing building…
How it runs
Agreed up front, so you always know what happens next and who is responsible for it.
We start with your brief: what the space needs to do, the budget you are working with, and the timeline you are aiming at. Honest feedback at this stage saves money later.
You receive: a written brief and an honest view on feasibility.
Measured survey of the site or existing building — levels, dimensions, structure and existing services. Decisions get made on facts, not assumptions.
You receive: measured site data — levels, dimensions, existing structure.
We develop the direction: layout, massing, materials and the reasoning behind them. You see the thinking, not just a render.
You receive: layout options, material direction and the reasoning behind them.
A transparent cost breakdown against a defined scope, plus the drawing set and specification the price is based on. You approve before anything starts.
You receive: a costed proposal against a defined scope, plus the drawing set it is priced from.
Execution phases managed tightly for quality and safety, with one coordinator across subcontractors, procurement and site. Progress reported as it happens.
You receive: scheduled progress reports and photographs from site.
Interior details, joinery, painting and final MEP connections — treated as part of the build, with the same standard as the structure.
You receive: finished joinery, painting and live MEP connections.
Snagging closed out, final walkthrough, documentation and keys. We finish the project with the same attention to quality that started it.
You receive: a closed snag list, handover documentation and the keys.
What you get
Not promises — the actual outputs of working with us.
A drawing set the site can build from, not just present from.
Priced against a defined scope before anything starts.
A single person across design, procurement, subcontractors and site.
Reported as it happens, in language you can actually read.
What was quoted is what gets installed. Substitutions get approved, not assumed.
Checked at structure, at finishing, and again before handover.
Electrical, plumbing and exhaust resolved with the build, not after it.
Not after your opening day. Finishing is part of the build.
Final walkthrough, documentation and keys — properly closed out.
Where we work
Every city below is somewhere we have finished a project, not somewhere we are willing to travel to. The count is the number of completed jobs on record.

Before you ask
Three things, under one roof: architecture, interior, and construction. You can engage any one of them on its own, or all three as a single design-and-build package with one point of accountability.
Because most project problems live in the hand-off. When the people who drew it are the people who build it, there is less reinterpretation, fewer variation claims, and nobody to blame but us.
We are based in Lakarsantri, Surabaya. Delivered projects include Surabaya, Sidoarjo, Gresik, Mojokerto, Mojosari, Pasuruan, Jombang, Banyuwangi and Semarang.
Yes — a single tenancy fit-out or a boundary fence is still a project we run properly. Tell us what you have in mind and we will be honest about fit.
Nobody can answer that responsibly without a scope. After an initial consultation and site survey we produce a transparent cost breakdown against a defined scope, so the number means something.
The initial conversation about your project is free. Formal design work and measured surveys are quoted before they start.
