Who you are dealing with

House of Parameters is run by Jad Daoud, a sole trader in Lebanon. There is one person behind the courses, the scripts and this site, and the address below reaches him and nobody else.

Write to hello@houseofparameters.com. These terms cover the use of this site and of anything bought through it. Using the site means you accept them.

What is on sale today, and what is not

No payment is taken on this site today. A script on the scripts page is bought by writing to me: I reply with how to pay, and the file comes back by email once it is paid. The licence below applies to a script bought like that exactly as it applies to any other, and a script that does not work is fixed or refunded, as the refund policy says. The waitlist takes an email address and nothing else, and joining it buys nothing and commits you to nothing.

Our order process is conducted by our online reseller, Paddle.com. Paddle.com Market Limited is the Merchant of Record for every order placed through the checkout on this site, for the scripts and the recorded courses: it takes the payment, issues the receipt, charges and remits any tax that is due, and handles customer service enquiries about the order and returns. The contract of sale for such an order is with Paddle, and Paddle's own terms apply to it alongside these. The course and the files are ours, and everything below about what a licence gives you is between you and us.

What a licence gives you

A course or a script is bought once, by one person, and it stays yours. Nothing renews and nothing expires. There is no subscription on this site.

You may:

• watch the lessons and use the files for your own work, including work you are paid for
• keep whatever you build with them, with no claim from us on it
• use the definitions and scripts inside a practice on projects you are working on

You may not:

• share an account, a download link or a login with anybody else
• republish, resell or redistribute the lessons or the files, in whole or in part, paid or free
• teach from the material, or use it as course material of your own, without written permission

Access is for one person because the price is for one person. A studio that wants licences for several people should write and ask; that is a different arrangement and a reasonable one.

Access, and when it can be taken away

Signing in is by a link sent to your email address, so there is no password to lose. Access to a course is revoked in two cases only: the purchase is refunded, or the account is being shared. Nothing else takes it away, and a revoked account is told why.

A refund ends the licence. A refunded script or course may no longer be used, and that includes any copy of its files already downloaded. Keeping and using a file after its money has come back is using it without a licence.

A script's download link carries Paddle's reference for the purchase. Each download is recorded against it, and it gives a set number of downloads, far more than one person needs, so a link passed round stops working. If yours runs out, write and it is opened again.

Prices

Prices are in US dollars. The same course costs different amounts in different countries, deliberately, and the price you are shown is the price for the country you are buying from. Any tax is added at checkout by Paddle, and the receipt Paddle issues shows it.

What the material is, and what it is not

The courses teach Grasshopper, Rhino and Rhino.Inside.Revit for architectural and engineering practice. They are instruction, not advice on your project. A definition from a lesson is a method, not a result you can hand to a client unchecked, and nothing here is structural, code compliance, safety or legal advice.

You remain responsible for what you build and for checking it. That is not a disclaimer hiding a weak course; it is how any tool works.

Rhino, Grasshopper and Revit are not ours. They are not included in any price here, and you need your own licences to follow the lessons.

Availability

The recorded courses are being filmed. No date is promised for any of them, and nothing on this site should be read as a date. The waitlist hears first when one opens.

The site itself is served by Cloudflare and is normally up, but no uptime is promised, and lessons, files and prices can change.

Liability

Where the law allows a limit, ours is the amount you paid for the thing the claim is about. Nothing here limits liability for fraud, or for anything that cannot be limited under Lebanese law.

The law that applies

Lebanese law, and the courts of Beirut.

Changes

The date at the top of this page is the last time it changed. A change never applies backwards to a purchase already made: the terms you bought under are the terms that govern that purchase.
