THE CHALLENGE
World-class design.
Hungarian permit requirements.
International architecture practices win competitions and commissions in Hungary – then face a wall of local statutory obligations. Every building permit requires a Hungarian chamber-registered architect and engineer to sign and seal the documentation. Project execution requires a construction manager who can hold design intent through a Hungarian tendering and contracting process. And since September 2024, BIM is mandatory for all qualifying state projects. BuildEXT bridges all three gaps under one roof.
01
Signing authority – a legal requirement, not a formality
In Hungary, permit design and construction design documentation must be sealed by architects and engineers registered with Magyar Építész Kamara and Magyar Mérnöki Kamara. The international design office’s drawings cannot go to the building authority without a licensed local signatory. BuildEXT provides this in-house across all disciplines.
02
Design supervision on site
Hungarian law requires the design architect to provide design supervision throughout construction. This is a statutory role with legal accountability – not optional project management. BuildEXT’s architects are embedded in your design process from the start, so they can credibly hold your intent through construction.
03
BIM mandatory since September 2024
The 31/2024. ÉKM decree mandates BIM for all qualifying state construction projects – with EIR, pre-BEP, BEP and CDE obligations active from design procurement. BuildEXT is fully aligned with every clause and can manage the information environment across the international design team.
04
Construction manager & technical inspector capacity
Successful project delivery in Hungary requires not only a qualified construction manager to coordinate works on site, but also a licensed technical inspector to verify contractual and statutory compliance. BuildEXT provides both roles – bridging the international design intent with on-the-ground Hungarian procurement and site management practice.
05
Continuity from tender to handover
Many practices engage a separate local firm for permit drawings only, creating a split between design intent and execution reality. BuildEXT’s model is different: we enter at tender stage, align with your design language, and carry that alignment through permit, construction supervision and FM handover.
OUR ROLE IN YOUR PROJECT
Design representation.
Not substitution.
BuildEXT does not replace the international design office. We are the local statutory and technical partner that makes your design buildable in Hungary – protecting design intent at every phase from permit to handover.
ROLE 01
Local design architect
We translate the international practice’s concept and scheme design into Hungarian permit-compliant documentation, signed and sealed by our registered architects. We manage all authority submissions, neighbour consultations and building permit proceedings – speaking fluent Hungarian regulatory language while protecting your design.
ROLE 02
Construction manager & design supervisor
We provide the statutory design supervision role throughout construction – attending site, reviewing contractor proposals, approving material substitutions, and resolving RFIs against the original design intent. This is not generic construction management: it is design-literate supervision by the architects who produced the permit drawings.
ROLE 03
Technical inspector
We provide a licensed technical inspector to verify contractor compliance with the construction contract, approved drawings and Hungarian building regulations throughout the execution phase – protecting the client’s interests, ensuring quality standards are met and providing the independent oversight required for statutory completion sign-off.
ROLE 04
BIM information manager
We manage the BIM information environment for the entire project – authoring the EIR, running the CDE, coordinating the federated model across the international design team and local engineers, and delivering IFC/BCF-format milestones as required by 31/2024. ÉKM. One information manager for the whole information chain.
ROLE 05
MEP engineering integration
We provide mechanical, electrical and plumbing engineering – fully BIM-coordinated and signed by registered Hungarian engineers. We integrate MEP into the international practice’s architectural model so the federated BIM remains coherent rather than fragmented across separately-contracted local sub-consultants.
ROLE 06
FM-ready BIM handover
We structure the as-built BIM model for facility management handover – with COBie/IFC datasets aligned with the client’s OIR and compliant with the 27/2025. ÉKM FM obligations. The digital twin survives construction and becomes a live operational asset for the building owner.
SERVICES
Full local capacity.
Every discipline.
Everything an international practice needs to build in Hungary – architectural design, engineering, BIM management, construction supervision, technical inspection and sustainability certification support – under one statutory roof.
General Design
Permit and construction documentation aligned with the international concept – signed by registered Hungarian architects across all disciplines. Authority liaison, neighbour notifications, building permit proceedings and all statutory consultations.
MEP Engineering
Mechanical, electrical and plumbing engineering – BIM-coordinated, ISO/EN compliant, aligned with BREEAM and LEED pathways. M, E and P licences in-house for all permit signatures.
Design Supervision & Construction Management
Statutory construction-phase design supervision by the same architects who produced the permit drawings. Site attendance, contractor RFI resolution, material approval, construction management and design intent protection through to practical completion.
Technical Inspection
Licensed technical inspector service – independent verification of contractor compliance with contract, approved drawings and Hungarian building regulations. Required for statutory completion sign-off on all qualifying projects.
HOW WE INTEGRATE INTO YOUR PROCESS
From tender stage
to FM handover.
BuildEXT can enter the project at any stage, but delivers most value when engaged at tender – allowing us to align with your design intent before the statutory process begins.
01 Tender & concept
We advise on Hungarian planning, zoning and programme requirements during tender entry and concept development – preventing compliance surprises late in the process.
02 Permit design
Permit design preparation aligned with your scheme design. All documentation signed and sealed. Full authority liaison, building permit proceedings and statutory consultations.
03 Construction BIM
LOD400 coordinated model across all disciplines. MEP integration, clash detection, tender package including BIM EIR requirements and mandatory cost schedules.
04 Construction supervision
Statutory design supervision – site attendance, RFI management, contractor approval, material substitution review, technical inspection. Design intent held to practical completion.
05 FM handover
As-built model snapshot, COBie/IFC FM dataset, structured for the client’s OIR. Annual model update cycle per 27/2025. ÉKM.
STATUTORY CREDENTIALS
Licensed.
Registered.
Accountable.
In Hungary, permit documentation must be sealed by registered chamber members. BuildEXT holds registered chamber membership and signature rights across all design disciplines in-house – so the firm designing your building is also the firm signing the permit, with no split in legal accountability.
Architectural design – Magyar Építész Kamara
Registered architects with full signing rights for permit-bearing architectural documentation. Provides the legal basis for design supervision and construction management on site.
MEP engineering – Magyar Mérnöki Kamara
Registered mechanical, electrical and plumbing engineers with signing rights for HVAC, heating, ventilation, fire protection, power distribution, LV systems and all building services documentation. All MEP disciplines covered under a single in-house team.
Technical inspector – Magyar Mérnöki Kamara
Licensed technical inspectors with signing rights to verify contractor compliance and provide the independent statutory inspection required for building completion certificates.
Why the signing split matters for international practices
Many international architecture practices work with a separate local firm for permit signing only – engaging them purely to provide the required stamp. This creates a structural problem: the local firm has no investment in the design, no understanding of its intent, and no authority to represent it to contractors. When the construction process generates RFIs, substitution proposals or value-engineering requests, there is no one with both design knowledge and statutory standing to defend the quality level the international practice intended.
BuildEXT enters the project as a design partner, not a stamp provider. Our registered architects and engineers understand what the concept requires before they sign the permit documentation – which means they can hold that understanding through design supervision, technical inspection, contractor queries and on-site decisions in the way that an arms-length signatory cannot.

HUNGARIAN REGULATORY FRAMEWORK
What every international practice
must know before building in Hungary.
Hungary has enacted comprehensive legislation governing both the architectural process and BIM information management since 2023. International practices who engage with Hungary without a compliant local partner risk permit delays, authority rejections and project liability.
| REFERENCE | REQUIREMENT &SCOPE | IMPACT ON INTERNATIONAL PRACTICE |
|---|---|---|
| 266/2013. (VII.11.) Korm. rendelet | Architectural and engineering professional qualifications decree Defines the professional qualification and chamber registration requirements for all architects and engineers who may sign permit documentation in Hungary. Foreign qualifications are not automatically recognised. All permit drawings must be signed and sealed by a person holding the relevant Hungarian chamber membership – regardless of who designed them. | SIGNING AUTHORITY |
| 312/2012. (XI.8.) Korm. rendelet | Building authority procedure and construction supervision rules Governs the building permit procedure – defining what documentation must be submitted, what consultations are required, and the legal standing of the parties involved. The design architect is a named statutory party with specific legal responsibilities during both permitting and design supervision. Technical inspector obligations are also defined here. | PERMIT PROCESS |
| 2023. évi LXIX. tv. (Ábtv.) | Act on the Order of State Construction Investments In force 8 November 2023. Governs all state-financed construction projects – establishing mandatory project documentation requirements, programme structures (BRF phases), and the legal basis for all subsequent BIM decrees. Defines design supervision obligations as a mandatory statutory role distinct from general project management, and sets construction manager and technical inspector requirements for qualifying projects. | STATE PROJECTS |
| 31/2024. (VIII.22.) ÉKM rendelet | BIM-Based Design & Technical Implementation Conditions In force 21 September 2024. Mandates BIM for all qualifying state construction tenders launched after this date. Requires EIR documentation in the tender pack, pre-BEP submission from the appointed design team, BEP maintenance throughout the project, a CDE platform, and delivery of models in IFC and BCF open formats at defined project milestones. | BIM MANDATE |
| 25/2024. (VIII.8.) ÉKM rendelet | Construction Investment Process System & Designer Services System Defines mandatory design phase content (BRF stages), tervzsűri design review obligations, and procurement conditions for design services in state tenders. Requires Hungarian chamber membership for all design professionals named in the procurement – directly affecting how international practices structure their team for Hungarian state bids. | PROCUREMENT RULES |
| 27/2025. (VIII.28.) ÉKM rendelet | State Asset Operation & Operator Selection Rules In force 27 September 2025. Extends BIM obligations into the operational phase – requiring FM-ready model handover at practical completion, annual model update obligations (by 15 March each year) and operator performance standards tied to digital asset management. Affects how projects for state clients must be designed from the outset. | FM HANDOVER |
