Services from preparation to operation
One partner
We manage design, engineering control and digital information management in one system, so every project participant can rely on the same up-to-date, verified information.
HOW WE HELP
3 dimensions, one platform
In every project, we connect three professional perspectives: design thinking, engineering control and digital continuity. This is the basis of how we work: whichever service area starts the collaboration, these three perspectives help make the project more transparent, better coordinated and more useful in the long term.
01
Design thinking
General design, architecture, interior design and discipline design in one data environment, from concept to construction documentation.
02
Engineering control
Client-side representation, cost and responsibility control, project management and practical constructability throughout the process.
03
Digital continuity
BIM-based workflows, a common data environment and structured information management, so project information is not lost between phases.
01 Engineering Consulting
Early decision support, technical preparation and strategic consulting, so the project starts in the right direction.


Investment decision support
BuildEXT supports clients in the early preparation phase by turning uncertain investment ideas, statutory requirements and technical constraints into structured, testable and comparable development directions.
We analyse the project context, help clarify the client’s objectives, and turn abstract ideas into a development basis that can be evaluated from both business and technical perspectives.
- Site and building potential analysis
- Functional and spatial feasibility studies
- Development scenarios and test fits
- Risk identification before design starts
- Early cost, schedule and scope assumptions
- Decision-support materials for owners, investors and management teams
The client receives a clearer picture of what is technically feasible, commercially justified and worth developing further — before unnecessary time and money are committed to the project.
02 General design
Architectural and discipline design in a coordinated system, from concept through permitting to construction documentation.


Our comfort zone begins where others reach their limits
We provide coordinated architectural and discipline design services, connecting design intent with technical feasibility, constructability and operability.
Thanks to our multidisciplinary way of working, the project develops in a controlled, model-based environment where design decisions remain aligned throughout the entire process.
- Architectural design from concept to detailed design documentation
- Discipline design and coordination
- BIM-based design and model coordination
- Clash detection and technical consistency checks
- Construction documentation
- Design support during tendering and construction
- Coordination with authorities, consultants and contractors
The client receives a coordinated, buildable and technically reliable design package that reduces information gaps, late-stage redesign and construction-phase uncertainty.
03 Interior Design
Workspaces, community spaces and business interiors designed in balance with function, brand, user experience and constructability.


BuildExt Business Experience – data-driven interior design
We design business interiors that go beyond aesthetics. Workplace strategy, BIM-based precision, carefully selected furniture and materials, sustainability considerations, visualisation and delivery support are brought together in one process.
The result is a workplace that supports hybrid work, collaboration, focused work, wellbeing and employer branding, while keeping design quality, cost control and long-term usability in balance.
- Hybrid-ready workplace design
- Wellbeing and employee experience
- BIM-based coordination and cost control
- Carefully selected materials, furniture and supplier background
- Sustainable, durable and operation-conscious solutions
- Archviz and VR for faster, clearer decisions
The client receives a measurable workplace investment: better employee experience, stronger brand perception, lower delivery risk and a more future-proof office environment.
04 Project management
Engineering-focused project management: controlled coordination of schedule, cost, quality, decisions and project participants.


A successful project is not measured by a good design alone
During delivery, we act as the client’s representative and ensure structure, coordination and transparency between design, procurement, construction and FM preparation.
Our project management approach is based on continuity and transparency. Our workflow supports design, coordination, reporting, issue tracking, decision preparation and quality control on one platform, helping the client make well-founded decisions throughout the project.
- Project planning and delivery strategy
- Coordination between the client, designers, consultants and contractors
- Scope, schedule and cost control
- Meeting structures, decision logs and reports
- Design and construction-phase coordination
- Risk, issue and change management
- Quality and documentation control
The client receives a more transparent and controlled project process, with clearer responsibilities, fewer surprises and better-prepared decisions throughout delivery.
05 Digital integration
BIM, CDE and data management solutions, so project information remains usable from design through operation.


We connect experience with technology
We manage the information created during the project in a common data environment that connects design, construction and operation through one controlled information structure.
The model and related data evolve continuously and remain structured, accessible and reliable throughout the full lifecycle.
- BIM and information management strategy
- Common Data Environment structure
- Model coordination and data standards
- Document control and version management
- Design and construction information workflows
- Scan-to-BIM and as-built model support
- Handover data and operation-ready information structure
The client receives a single verified information base for the project: structured, traceable and reusable data that supports decisions during design, construction and operation.
INFORMATION CONTINUITY IN A COMMON DATA ENVIROMENT
From decision preparation to handover
One of the biggest risks in projects is information loss. At BuildEXT, the 5 service areas are connected by the 3 professional dimensions and CDE-based workflows, so no project information is lost between decision preparation, design, delivery and handover.
01 Clarifying engineering foundations and project objectives
Client objectives, existing conditions, documentation, risks and information gaps are identified. The project starts on structured foundations.
➔ clearer decision preparation, less uncertainty
02 Digitising the existing condition and design basis
Surveys, existing documentation, Scan-to-BIM or other sources are used to create a verified design basis that can be carried forward.
➔ more reliable starting point, fewer incorrect assumptions
03 Design in a coordinated data environment
General design, interior design and discipline decisions are not made in isolation. They develop together, building on a shared information background.
➔ better coordinated design, less information loss
04 Project control and delivery support
Decisions, changes, open issues, deadlines and technical coordination are based on the same information foundation.
➔ more transparent project management, stronger technical control
05 Construction follow-up and feedback
Designer queries, on-site clarifications, changes and discipline coordination can be managed in a documented, traceable way.
➔ faster response time, fewer open technical issues
06 Digital handover and usable project data
At the end of the project, not only documentation is produced, but also organised technical information that supports operation, later refurbishments and future developments.
➔ more transparent handover, more usable technical background
CASE STUDIES
Development areas
In investment projects, the task is often not limited to a single building. Existing infrastructure, operational processes, utilities and new technological requirements together define the direction of development.


Complete site development
Accurate starting data through Scan-to-BIM, so refurbishment and transformation design can be based on verified building information instead of assumptions.

CERTIFICATION
“Transforming a more than 37,000 m² heritage industrial facility into an international-level model factory is a demanding task that requires serious commitment and resilience. I have been working on the development of the Continental Budapest site for more than five years with the n-Gon team, later BuildEXT, and during this overall investment of more than HUF 40 billion, I had many opportunities to get to know them in challenging situations.
With their creativity, broad engineering knowledge and advanced BIM design technology, they often showed new ways forward and delivered even seemingly impossible commitments on time. They grew together with the project, represented the client’s interests and consistently delivered high-quality designs.
They are a reliable, flexible partner and a team we enjoy working with. Thank you for the successes we have achieved together.”
