Terms of Business — Architectural Visualisation

Effective date: 21 July 2026
Contact:UK@turzen.com

1. Parties and application

These Terms govern services provided by TURZEN UK LTD, Company No. 16688889, registered in England and Wales, with its registered office at 71–75 Shelton Street, London, WC2H 9JQ (“TURZEN”, “we”, “us” or “our”), to the business client identified in the applicable Order (“you” or “the Client”).

These Terms are intended for business-to-business services. If you are acting wholly or mainly outside your trade, business, craft or profession, please contact us before placing an Order.

The contracting entity for new business governed by these Terms is TURZEN UK LTD. These Terms do not replace or change the contracting entity under any existing signed agreement.

2. Definitions

“Deliverables” means the still images, animations, videos, interactive previews or other agreed outputs identified in the Order.

“Order” means our accepted quotation, statement of work, purchase order, project brief or other written document specifying the services, Deliverables, fees and schedule.

“Project Materials” means models, drawings, references, designs, images, data and other materials provided by you or on your behalf.

“Revision Round” means one consolidated set of feedback provided by your authorised reviewer at an agreed review stage.

3. Services and scope

We provide architectural visualisation services, which may include still renderings, animations, interactive or immersive previews, visual development, model preparation and related production work.

The precise services, Deliverables, resolution, views, schedule and fees are specified in the Order.

Our services support visual communication and design decision-making. They do not constitute architectural, engineering, surveying, planning, regulatory, cost or construction advice. Deliverables are not construction documents or proof of technical or regulatory compliance.

4. Formation of the contract

A contract is formed when you accept an Order in writing, including by email or purchase order.

A 30% upfront payment is required before we schedule and commence production. We may also require the agreed Project Materials and project brief before work begins.

5. Order of precedence

The contract consists of:

  1. any specifically negotiated and signed agreement between the parties;

  2. the applicable Order and agreed project brief; and

  3. these Terms.

If these documents conflict, they apply in the order listed above.

An existing signed Long-Term Cooperation Agreement or other bespoke agreement continues to govern work issued under that agreement where its terms differ from these Terms.

6. Your responsibilities

You must:

  • provide accurate and sufficiently complete Project Materials, including relevant models, drawings, site information, material references, view requirements, landscape information and mood or lighting references;

  • ensure that you have the right to provide and authorise our use of all Project Materials;

  • identify one authorised reviewer who can approve views and provide consolidated feedback;

  • provide decisions, approvals and feedback within the agreed schedule;

  • notify us promptly of design, model, brief or programme changes; and

  • review the Deliverables for design accuracy and suitability for your intended use.

We are entitled to rely on the information and instructions you provide. Delayed, incomplete, inaccurate or changed inputs may affect the schedule and fees.

7. Schedule and milestones

We will agree an appropriate production schedule and review milestones at the beginning of the project.

Unless expressly stated as fixed in the Order, delivery dates are estimates. We will use reasonable skill and care to meet agreed targets.

The schedule may be adjusted if:

  • Project Materials or feedback are late or incomplete;

  • the brief, design or model changes;

  • previously approved views or animation paths are changed;

  • additional Deliverables or Revision Rounds are requested; or

  • circumstances outside our reasonable control affect production.

Camera position and view approval are project milestones. A material camera or view change requested after approval may require additional time and fees.

8. Fees and payment

Unless stated otherwise in the Order:

  • the default billing currency is GBP, although another currency, including USD, may be used where stated in the Order;

  • 30% of the agreed project fee is payable upfront before production begins;

  • the remaining 70% is payable when the final Deliverables are approved;

  • final high-resolution Deliverables and the licence described in section 11 are released after payment has cleared;

  • payment instructions and the applicable due date are stated on the invoice; and

  • fees exclude VAT, where applicable, and exclude third-party costs unless expressly included.

You must pay invoices without deduction, counterclaim or set-off unless required by law.

We may suspend work or withhold final Deliverables while an invoice is overdue.

Statutory interest and recovery costs may apply to overdue business debts under the Late Payment of Commercial Debts (Interest) Act 1998.

9. Revisions and changes

Three Revision Rounds are included at no additional charge.

Each Revision Round means one consolidated set of feedback from your authorised reviewer at an agreed review stage. Separate or fragmented comments may delay the project and may be treated as separate rounds where they require additional production work.

Included revisions must remain within the agreed brief. Corrections of a clear error by us do not count as a Revision Round.

The following are changes of scope and may require revised fees and delivery dates:

  • additional views, sequences or Deliverables;

  • feedback beyond the three included Revision Rounds;

  • changes to the client’s design or model after work has begun;

  • changes to an approved camera, view or animation path;

  • a new creative direction after mood or style approval;

  • significant changes to materials, landscape, lighting or staging after approval; and

  • changes requested after final approval.

We will notify you before undertaking material additional work and will agree the effect on fees and timing in writing.

10. Approval and delivery

Approval must be provided by your authorised reviewer in writing, including by email or through an agreed project-review platform.

Final file formats and resolution are specified in the Order. Unless otherwise agreed:

  • still images are supplied as high-resolution JPG or PNG files; and

  • animations are supplied as MP4 files using a standard delivery codec.

Layered files, source files, 3D scenes, working models, PSD, EXR or similar production files are not included unless expressly stated in the Order.

Interim previews are provided for review and must not be treated as final Deliverables.

11. Intellectual property and licence

You retain ownership of the designs and Project Materials you supply. You grant us a limited right to use them solely to perform the services and administer the project.

We retain ownership of our production methods, working files, scene files, templates, tools, reusable assets, know-how and other background intellectual property.

Once all fees for the relevant Order have been paid, we grant you a non-exclusive, worldwide, perpetual licence to use the final Deliverables for:

  • planning and consultation;

  • project marketing and promotion; and

  • internal presentations and design review.

The licence also permits your appointed consultants, agents and marketing providers to use the Deliverables on your behalf for these purposes.

Unless we agree otherwise in writing, you may not:

  • resell or license the Deliverables as standalone assets;

  • place them in a stock-image or asset library;

  • claim that another visualisation provider created them; or

  • use the Deliverables, or derivatives of them, to train, fine-tune, test or evaluate an artificial-intelligence model.

Any use outside the permitted purposes requires our prior written agreement.

Where reasonably practicable after public release, please credit “© TURZEN”, unless an NDA, client policy or written agreement prevents this.

12. Portfolio and publicity

We will not publish confidential or unreleased Project Materials.

Unless the Order, an NDA or your written instructions state otherwise, we may display final Deliverables in our portfolio, website, presentations and professional social channels after the project has been publicly released by you, the project owner or an authorised party.

We will not pre-empt your public announcement. You may notify us in writing before publication if portfolio use is restricted.

13. Confidentiality and production support

Each party must protect the other party’s confidential information and use it only for the project or the administration of the business relationship.

We may use production personnel and specialist subcontractors, including personnel based in Beijing, to perform parts of the services. We remain responsible for the services we provide and limit project access to personnel who need it for production or project administration.

Personal information is handled in accordance with our Privacy Policy.

14. Warranties and reliance

We warrant that we will perform the services with reasonable skill and care.

Visualisations are representational. Unless expressly included in the Order, we do not independently verify dimensions, specifications, materials, planning requirements, technical feasibility or regulatory compliance.

You remain responsible for checking the architectural and technical accuracy of the Deliverables before using them for planning, marketing, construction-related decisions or public communication.

15. Liability

To the fullest extent permitted by law:

  • our total liability arising from an Order is limited to the fees paid to us under that Order;

  • we are not liable for indirect or consequential loss, loss of profit, loss of revenue, loss of opportunity, loss of anticipated savings or reputational loss; and

  • we are not liable for errors arising from inaccurate, incomplete or late Project Materials or instructions supplied by you or on your behalf.

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud, fraudulent misrepresentation or any liability that cannot legally be excluded or limited.

16. Suspension, cancellation and termination

We may suspend work if an invoice is overdue, required Project Materials are not provided, or you materially breach the contract.

If you cancel or place a project on hold, you must pay for:

  • work completed up to the effective date of cancellation or suspension;

  • reasonable committed production time that cannot be reallocated; and

  • non-cancellable third-party costs.

Any upfront payment already received will be credited against the amount due.

Either party may terminate the contract for a material breach that is not remedied within a reasonable period after written notice, where the breach is capable of remedy.

Termination does not affect accrued payment obligations or rights that are intended to continue after termination.

17. Force majeure

Neither party is liable for delay or failure caused by circumstances beyond its reasonable control, including serious network or power failure, natural disaster, epidemic, industrial action, government action, civil disturbance or failure of a critical third-party service.

Affected deadlines will be extended reasonably. Either party may terminate the affected Order if the event continues for more than 30 days and materially prevents performance.

18. Notices

Formal notices may be sent to UK@turzen.com and to the Client’s most recently notified email or postal address.

An email notice is treated as received when sent, provided that the sender does not receive a delivery-failure notification.

19. Governing law and jurisdiction

These Terms and any non-contractual dispute arising from them are governed by the laws of England and Wales.

The courts of England and Wales have exclusive jurisdiction, unless a specifically negotiated and signed agreement governing the relevant Order states otherwise.

20. General

We may subcontract parts of the services while remaining responsible for our contractual obligations.

Neither party may assign the contract without the other party’s written consent, which must not be unreasonably withheld.

If any provision is invalid or unenforceable, the remaining provisions continue in effect.

A failure or delay in enforcing a right is not a waiver of that right.

Changes to an Order or these Terms must be agreed in writing.

No person other than the parties has a right to enforce the contract under the Contracts (Rights of Third Parties) Act 1999.
