Our Services
What we build — and how we build it.
Three core services. One standard of engineering excellence. Every project managed from first consultation to final handover.
Our services
Every project is managed by qualified engineers from start to finish.
Most contractors will tell you they build well. What sets Sieben apart is the team behind every project: qualified civil, structural, and mechanical engineers who oversee each stage of construction — from foundation design to finishing details. This is not supervision for its own sake. It is the difference between a build that is done and a build that is done properly.
We offer three core services: new home construction, home renovation and rehabilitation, and commercial construction. Across all three, our approach is the same — clear scope, transparent costs, structured reporting, and a team that keeps you informed at every stage whether you are five minutes away or five thousand kilometres.
Service 01
New Home Construction
Building a new home is one of the most significant investments you will ever make. You deserve a contractor who treats it that way — one who brings engineering expertise to every decision, communicates without being chased, and delivers a finished home you are proud to walk into.
At Sieben, we manage your new build from the ground up. Our team of civil and structural engineers reviews your plans, assesses site conditions, and oversees every stage of construction — foundation, structure, roofing, electrical, plumbing, and finishing. You receive a formal project scope and cost breakdown before any work begins, so there are no surprises.
Throughout the build, you receive regular written progress reports and WhatsApp updates at every key milestone. If you are building from abroad, this is how we make distance irrelevant: you will always know what is happening on your site, even from the other side of the world.
This service includes:
- Initial consultation and project scoping
- Engineering and architectural oversight throughout
- Formal project scope, timeline, and cost breakdown before work begins
- Foundation, structure, roofing, and full finishing works
- Regular formal progress reports and WhatsApp milestone updates
- Dedicated point of contact for the duration of the project
- Final inspection and professional handover
Service 02
Home Renovation and Rehabilitation
Not every project starts from a clean slate. Some clients come to us with a renovation that has stalled, a build that was handed over below standard, or an existing property that needs significant work to reach its potential. This is work we know well, and work we take seriously.
Before any renovation work begins, our engineers conduct a thorough assessment of the existing structure. We identify what needs to be corrected, what can be preserved, and what the most cost-effective path to the outcome you want looks like. You receive a clear scope and honest cost estimate — no inflated surprises, no cutting corners to save margin.
Whether you are upgrading a kitchen, rehabilitating a full property, or completing a build that another contractor left unfinished, Sieben brings the same engineering rigour and transparent communication to every renovation project. You will know exactly what we are doing, why we are doing it, and what it costs.
This service includes:
- Structural assessment of the existing property before work begins
- Honest scope and cost estimate — no hidden fees
- Correction of substandard workmanship where required
- Completion of stalled or unfinished builds
- Kitchen, bathroom, and interior renovation
- Full property rehabilitation and upgrading
- Regular progress reporting throughout
- Professional handover on completion
Service 03
Commercial Construction
A well-built commercial space is more than a functional structure. It is a statement of how your organisation operates — and a reflection of the standards you hold yourself to. Sieben brings the same engineering discipline and project management rigour to commercial builds as we do to every home we construct.
Our commercial construction experience spans office buildings, institutional facilities, and multi-unit developments. We work with businesses and organisations who need a contractor that can handle the full scope of a commercial project — from design coordination through to structural completion and fit-out.
For institutional clients, we understand the additional requirements that come with procurement processes, compliance standards, and reporting expectations. Our team is experienced in working within these frameworks, and our track record with organisations including the US Embassy Zambia and Zamtel demonstrates our capacity to meet institutional standards.
This service includes:
- Office buildings and institutional facilities
- Multi-unit residential developments and blocks of flats
- Warehouse and commercial infrastructure
- Engineering and architectural coordination
- Compliance with Zambian building codes and standards
- Formal project reporting suitable for institutional procurement requirements
- Professional handover with full documentation
