§ 1 Scope

These Terms & Conditions ("Terms") apply to all contracts between

Designcore Consulting FZCO represented by Diana Hirt

Email: info@dianahirt.com

– hereinafter the "Designer" – and the respective client regarding consulting, interior design and space-planning services.

A "consumer" within the meaning of these Terms is any natural person who enters into the contract predominantly for private purposes. A "business client" is any natural or legal person who enters into the contract in the course of their commercial, self-employed or professional activity.

The specific scope of services results from the relevant service description, booking, quote or an individually concluded contract. Individual agreements take precedence over these Terms.

Unless stated otherwise, quotes are valid for 14 days from the date of the quote.

§ 2 Conclusion of contract

For services bookable online, the contract is concluded once the booking and payment process has been completed.

For individually offered services, the contract is concluded upon acceptance of the quote or signing of the respective contract.

Changes, extensions or services beyond the agreed scope require prior coordination and will be charged separately.

§ 3 Scope and nature of the services

The Designer provides exclusively the consulting and planning services agreed in the relevant service description, booking, quote or individual contract. Services not expressly agreed are not owed.

The Designer's services are, in principle, of a creative and interior-planning nature.

Depending on the engagement, these may in particular include design consulting, floor-plan and furnishing planning, interior concepts, moodboards, colour and material concepts, creative lighting planning, kitchen and bathroom concepts, 2D/3D visualisations, agreed planning and detail drawings, as well as product and shopping lists.

Design Call and Floor-Plan Check

The Design Call and Floor-Plan Check are exclusively creative consulting/concept services. They serve the creative assessment, optimisation and development of solution approaches for the respective project.

Any specific technical, structural, constructional, economic or regulatory feasibility of the recommendations, floor-plan variants or other suggestions developed as part of these services is not owed.

In particular, floor-plan variants, furnishing suggestions, 3D renderings, recommendations or other documents developed as part of a Design Call or Floor-Plan Check do not constitute permit, works, production, execution or technical specialist planning.

Before any structural or technical implementation, the suggestions must be reviewed for technical, structural and regulatory feasibility by the relevant specialist planners, authorities or executing trade businesses.

§ 4 Technical scope, local regulations and permits

Unless expressly agreed as a contractual service, the Designer does not owe, in particular, structural or load-bearing design, permit planning, site management, site supervision, or electrical, plumbing, heating, ventilation or other technical specialist planning.

Positions shown, in particular of light fixtures, sockets, kitchen, sanitary or furnishing items, are to be understood as creative planning suggestions.

Technical feasibility, required connections, and compliance with technical, building-law and other public-law requirements must be reviewed before execution by the responsible specialist planners, authorities or trade businesses.

Any lighting design produced by the Designer is, unless expressly agreed otherwise, a creative lighting design and not electrical specialist planning.

Reviewing and complying with the public-law, building-law, technical or other local regulations, permit requirements and building rules applicable at the respective project location is not part of the service, unless expressly agreed.

This applies in particular to projects outside the Designer's home jurisdiction.

§ 5 Measurements, existing documentation and site surveys

The Designer is entitled to base their services on the plans, measurements, photos, existing documentation and other information provided by the client, unless their incorrectness or incompleteness is obviously apparent.

The client is responsible for the accuracy and completeness of the information and documents they provide.

Before ordering, manufacturing or installing size-dependent products, furniture, built-ins or components, a binding on-site survey by the executing trade business is required.

An inspection or examination of the existing building fabric for, in particular, hidden defects, moisture, hazardous substances, structural conditions or other non-apparent constructional properties is not part of the service, unless expressly agreed.

§ 6 Prices and payment terms

The prices and currency shown at the time of booking or in the relevant quote apply.

Any taxes or levies are shown in accordance with the applicable statutory provisions.

Services bookable online, in particular the Design Call and Floor-Plan Check, are due in full upon completion of the booking.

For individually commissioned interior planning, unless otherwise agreed in the quote, the following payment schedule applies:

• 50 % upon commissioning
• 40 % upon completion and approval of the design concept or 3D planning
• 10 % before handover of the final documents

Work begins once the agreed first payment has been received.

Additional services, subsequently commissioned services and agreed third-party costs are charged separately.

In the event of late payment, the applicable statutory provisions apply.

§ 7 Appointments, cancellation and rescheduling

For services with a scheduled appointment, the appointment conditions stated at the time of booking apply.

Unless otherwise agreed, scheduled appointments may be cancelled free of charge or rescheduled once up to 24 hours before the start.

In the event of a later cancellation, rescheduling or a no-show, there is, to the extent legally permissible, no entitlement to a refund of the fee paid.

If an appointment cannot take place for reasons the Designer is responsible for, a replacement appointment will be offered or the fee paid for that appointment will be refunded.

Mandatory statutory rights of the client, in particular any statutory right of withdrawal, remain unaffected.

§ 8 Client's duties to cooperate

The client shall provide all information, documents, plans, measurements, photos, decisions and approvals required for the proper performance of the service completely and in good time.

Delays caused by missing or late cooperation by the client, subsequent change requests, or third-party services may lead to a corresponding extension of the agreed processing times.

If a project is paused for more than 30 days due to lack of cooperation or at the client's request, a rescheduling of the project may be required.

Any additional effort resulting from this, in particular for updating products, prices, availability or planning documents, may be charged separately following prior coordination.

§ 9 Visualisations, renderings, colours and materials

Visualisations, renderings, moodboards and comparable representations serve to illustrate the design concept and do not constitute an assurance of an identical later execution.

Colours, materials, textures, surfaces, proportions and lighting effects may deviate from the representation, in particular due to screen display, lighting conditions, material properties, product changes or production batches.

For significant colour, material or surface decisions, it is recommended to check real samples or product samples before ordering or execution.

Visualisations and renderings do not constitute technical working, production or execution drawings, unless expressly agreed otherwise.

§ 10 Revisions, changes and approvals

The scope of included revisions depends on the respective booked service or quote.

For Interior Planning, unless otherwise agreed, up to three rounds of revisions are included during the design phase.

Once the design concept has been approved, finalisation of the planning documents begins.

Further revisions, changes made after approval, or services beyond the agreed scope will be charged as an additional service following prior coordination.

Approvals and consents may be given in text form, in particular by email or via a digital communication channel agreed between the parties.

§ 11 Products, shopping lists and material recommendations

Shopping lists and product, furniture and material recommendations are non-binding recommendations by the Designer.

The client makes their purchasing decisions on their own responsibility.

Unless expressly agreed otherwise, the Designer does not order products in the client's name or on their account. Purchase contracts are concluded exclusively between the client and the respective retailer, manufacturer or seller.

Before placing an order, the client must check, in particular, the product, model, finish, colour, dimensions, quantity, price, availability and delivery terms.

Dimensions, required quantities, on-site measurements and required cutting allowance must be bindingly verified before ordering by the relevant trade business or retailer.

The client's respective contractual partner is responsible for product defects, delivery delays, range changes, unavailability or warranty claims.

§ 12 External specialist planners, tradespeople and other service providers

Tradespeople, specialist planners, suppliers or other external service providers may be recommended at the client's request.

A recommendation does not establish site management, site supervision or technical responsibility on the part of the Designer for the recommended company's services.

Unless expressly agreed otherwise, contracts with external companies are concluded directly between the client and the respective company.

The respective company is itself responsible for its services, in particular for binding on-site surveys, technical review and planning, compliance with local regulations and permits, and proper execution.

If plans or recommendations by the Designer are altered by the client or third parties, the Designer is not responsible for any resulting consequences, insofar as these are not attributable to the Designer and to the extent legally permissible.

§ 13 Documents, copyright and usage rights

The client generally receives the final documents agreed within the respective scope of services in digital form.

Open working files, 3D models, source files or other editable files are not part of the handover, unless expressly agreed.

Drafts, concepts, drawings, visualisations, renderings and other documents created by the Designer remain the Designer's intellectual property.

Upon full payment, the client receives the simple right of use required for the specifically commissioned project.

Any use for other projects, reproduction for purposes other than those contractually intended, commercial distribution, or any other use beyond this requires the Designer's prior consent, unless mandatory statutory rights provide otherwise.

The Designer may use their own designs, plans and visualisations for portfolio, website, social-media and other self-promotional purposes, provided this does not publish any personal data of the client.

Photos of completed private spaces are published only with the client's consent.

§ 14 Liability

The Designer is liable without limitation for intent and gross negligence, as well as for damages resulting from injury to life, body or health.

In the event of slightly negligent breach of material contractual obligations, liability is, to the extent legally permissible, limited to the typically foreseeable damage.

There is no liability for damages or planning deviations based on incorrect, incomplete or subsequently changed information, plans, measurements or documents provided by the client, provided their inaccuracy was not obviously apparent to the Designer and the damage is not attributable to the Designer.

The Designer assumes no responsibility for the technical, structural, constructional or regulatory feasibility of purely creative consulting and planning services, nor for compliance with local technical or public-law regulations, unless their review is expressly part of the agreed scope of services.

The Designer is not liable for the services of independent specialist planners, tradespeople, retailers, manufacturers, suppliers or other third parties, provided their conduct is not legally attributable to the Designer.

Mandatory statutory liability provisions remain unaffected.

§ 15 Termination of individually commissioned services

Termination of individually commissioned services is governed by the applicable statutory and contractual provisions.

Services already duly rendered up to termination of the contract, as well as agreed and already incurred third-party costs, will be invoiced accordingly.

Mandatory statutory rights of termination and withdrawal of the client remain unaffected.

§ 16 Right of withdrawal for consumers

Insofar as a consumer has a right of withdrawal under the statutory provisions applicable to the respective contract, the corresponding statutory provisions and the withdrawal instructions provided by the Designer apply.

If a statutory 14-day right of withdrawal exists and the consumer expressly requests that the Designer begin the agreed service before the end of this withdrawal period, the service may be started early.

In the event of an effective withdrawal after the service has already begun, the consumer may, in accordance with the applicable statutory provisions, be obliged to pay proportionate compensation for the services rendered up to the withdrawal.

Where a paid service has been fully performed, the right of withdrawal may lapse under the statutory conditions, in particular where the consumer has expressly agreed, before the service began, to the early start of performance and has confirmed their knowledge that their right of withdrawal lapses upon full performance of the contract.

The contractual cancellation terms under § 7 do not affect any statutory right of withdrawal that may exist.

§ 17 Data protection and confidentiality

Personal data is processed in accordance with the applicable data-protection provisions. Details can be found in the privacy policy published on the website.

The parties undertake to treat as confidential any information and documents expressly designated as confidential or whose confidentiality arises from the circumstances, unless there is a statutory obligation to disclose.

§ 18 Governing law and jurisdiction

To the extent legally permissible, the law of the Federal Republic of Germany applies to all contractual relationships.

For consumers, this choice of law applies only insofar as it does not deprive them of the protection granted by mandatory provisions of the law of the state of their habitual residence.

Mandatory statutory consumer-protection provisions remain unaffected.

For consumers, the applicable statutory rules on jurisdiction apply.

For business clients, to the extent legally permissible, the Designer's registered seat is agreed as the place of jurisdiction.

§ 19 Final provisions

Should individual provisions of these Terms be or become wholly or partly invalid or unenforceable, the validity of the remaining provisions shall remain unaffected.

Invalid or unenforceable provisions shall be replaced by the applicable statutory provisions.

Mandatory statutory rights of the client remain unaffected.
