General Terms and Conditions (GTC)


Orders are accepted accepted in writing, via email or by telephone.
On confirmation of the order a legally binding sales contract has been entered into.

Automatic acceptance of my General terms and Conditions has been agreed by placing an order.

All business is subject to my ‘Terms and Conditions of Payment and Delivery’ without exception.

Payment and delivery

Shipping of construction plans is after receipt of payment resp. payment of outstanding sum to my account at the Sparkasse Siegen, Account No. 70 70 11 72, Bank code: 460 500 01 (IBAN-No: DE 43 4605 0001 0070 7011 72, BIC-Code: WELADED 1 SIE), by Paypal at or COD.
Shipments outside Germany are only after receipt of payment.
Shipping is at the risk of the purchaser.

I do my best to deliver on time in accordance with agreed delivery dates, however, any demand for compensation as a result of delayed delivery is out of the question.

The prices quoted are final prices but do not include shipping and packing, for which I charge the actual cost incurred.

The goods remain my property until payment has been made in full. I reserve the right to make any technical amendments deemed necessary.


Claims must be made within 6 working days in writing. Any fault that is proven to be due to materials or manufacturing faults will, after inspection, be compensated.
No liability whatsoever shall be accepted for damage to property or persons resulting from the use of my products.

The construction plans are generally excluded from exchange or replacement.

Applicable law and place of jurisdiction

For all deliveries Siegen is the applicable law and place of jurisdiction. The contract is made in accordance with German law.
