Take a few seconds to get familiar with the free-D website and its features.

free-D.nl is the place to share & find free form architecture, facades & theory

free-D has hundreds of buildings categorized by their shape and special features

on each portal you find a gallery of new projects you can browse through

icons are highlighted for the active project to indicate its shape and features

the active project is directly marked on the free-D world map

click on a project to find out more about it: more images, video, texts & comments

if you are looking for a specific project, you can simply use the search...

...or click on an icon to filter all the projects with that shape or feature

whatever free form you are looking for, you'll find it here, on free-D.nl

enjoy exploring!

Sheared

Sheared

Shear, when the floors are moved sideways in parallel, the manipulation is called shearing. The building volume, floor height and floor contours when shearing stay the same.

Bent

Bent

Bent, the building volume is transformed by curving along the axis connected to it. The angle direction can be controlled along the desired axis.

Scaled

Scaled

A volume can be scaled in the directions of the 3 axis, or be scaled following other prescriptions, for example, be scaled relative to a chosen point.

Twisted

Twisted

A volume is twisted, in relation to an axis connected to the building. The speed of rotation can vary, and the axis need not lie in the centre of the volume, nor be straight.

Line Controlled

Line Controlled

By this command, a line on a surface like a surface contour, can be moved and be changed in shape.

Field Controlled

Field Controlled

By this command a selected surface part of a volume can be transformed.

Boolean Operated

Boolean Operated

Boolean operations allow for quick sculpting, by for example adding (Unite) or deducting (Remove) parts resulting from intersections with other volumes.

Box

Box

A box is a cube primitive already scaled to the right proportions.

Cylinder

Cylinder

A solid bounded by a cylindrical surface and two parallel circular planes (the bases).

Sphere

Sphere

made by rotating a generating half-circular arc around an axis.

Pyramid

Pyramid

Volume created by connecting sides of a base polygon with triangular faces meeting at an apex.

Cone

Cone

made by rotating a straight line around an axis with one line end on the axis.

Extruder

Extruder

Volume described by moving a closed line along another line.

Line Sweeper

Line Sweeper

Volumes generated with moving a curve(s) along one or two tracks viz. curve(s).

Skinner

Skinner

A volume created by generating a surface over a network of closed and/or open curves. The Skinner category also includes the Mergers (i.e. the volumes of which the surface is made between a closed line and a point or line).

Revolver

Revolver

made by moving a generating line around an axis.

Compound  volume

Compound volume

A compound volume is a volume built by combining two or more complex shaped volumes and/or surfaces.

about free-D.nl

free-D.nl: the online documentation platform on non-orthogonal buildings. The motivation and relevance of the free-D project is based on the increasing degree of geometrical variation and complexity in non-orthogonal buildings worldwide.
