Rough and Ready Chair

Published in Fall 2019

Tord Boontje’s visually striking Rough and Ready Chair utilizes a simple engineering trick, enhancing the strength of the brittle square frame by placing diagonal wooden pieces all around it. Its aesthetics are defined by whatever wood or spare blankets you happen to have on hand. The full assembly process takes up to 2 hours to complete, and the cost of parts really relies on how much you happen to already have. The design is also relatively easy to manipulate in order to make a bench or a stool.

Hempcrete Stool

Hempcrete DIY Stool by Ian Anderson
Hempcrete Stool

Design and photography by Ian Anderson
Published in Fall 2019

In making this stool, you will be producing an unconventional yet efficient building material with both insulation and thermal mass properties. Made up of hemp hurd, lime, and a binder material, hempcrete (as a single material) is a natural and carbon negative alternative to the abundant layers of insulation, drywall, cladding, etc… that cover the walls of our homes today. In some ways, the simple instructions for this stool are the same as instructions for building a wall of your home with this material. More on hempcrete here. The simple assembly process takes up to 1 hour to complete.

Sedia 1 Chair

Designed by Enzo Mari
Published in Fall 2019

Originally published in Enzo Mari’s Autoprogettazione, alongside a full collection of easy to assemble furniture, the Sedia 1 Chair has emerged as the most recognized piece from the collection. It requires the simple manual processes of sawing lengths of softwood and hammering the pieces together with nails. The full assembly process takes up to 2 hours to complete. Each chair costs under 25 USD on average to produce.

Crate Chair

Designed by Gerrit Rietveld
Published in Fall 2019

Rietveld’s Crate Chair (1934) was designed with a particular interest in using recycled materials. Building instructions for most of Rietveld’s designs have since been published in the 1986 book How to Construct Rietveld Furniture. Because this chair was originally produced, and it was not designed specifically as a DIY chair, it does require quite a lot of wood and more time spent with a saw. Assembly time is about 3 hours and the average cost is under 50 USD.

Published in Fall 2019

The Two by Two Chair ambitiously utilizes a webbing system to form its seating surfaces. The builder is required to stretch and nail in each strap so that there is no slack when the chair is complete. Its shape is reminiscent of Rietveld chair designs, but it makes some ergonomic concessions learned from more modern chairs, where the back support cradles ones lower back with minimal pressure. The full assembly process takes a little over 3 hours to complete and the parts cost 50 USD on average.

Featured in the essay Make This Chair., the Two by One Chair design was used as a pretext to pursue a discussion on DIY and the modern condition. It requires a minimal amount of materials by utilizing the triangle to both enhance the structure of the chair and define its aesthetic (much in the same way Enzo Mari and Tord Boontje did with their DIY designs). The full assembly process takes about 2 hours to complete and the parts cost less than 20 USD on average.

Published in Fall 2019

A DIY chair’s instructions are just as significant as the design of the DIY chair itself. The DIY Chair by Max Lamb, designed in 2008, is one of the more modern DIY chairs around, mainly because of the way Max chose to communicate the process of making the chair. The simple step-by-step method that he employed meticulously controls the process of production with detailed notes. The simple but time consuming assembly process takes up to 4 hours to complete. Parts cost under 50 USD on average.

Utility Pendant Light

Design and photography by AANDERSSON
Published in Spring 2019

Designed alongside the One Gallon Floor Lamp and using similar utility-oriented parts, this pendant light replaces the standard pull chain switch and exaggerates the simple task of turning on a light. The full assembly process takes about 2 hours to complete. Steps include drilling a hole in the acrylic ball shade, wiring the lamp, and installing the moving strap switch. The parts cost a little over 100 USD on average.

Extrusion Large Vase

Extrusion Large Vase

Design and photography by AANDERSSON
Published in Spring 2019

Hollow 80mm T-slotted framing is a natural form for a vessel. The extrusion process creates beautiful and functional grooves on the exterior as well as weight and material saving cavities on the interior. The full assembly process for the 9.5in (24cm) tall vase takes less than 1 hour to complete. Steps include applying a rubber pad and sealer to the bottom and filling the cavities with some epoxy glue. The parts cost less than 100 USD on average. While caring for your anodized (non-black) vase, clean and re-fresh water regularly to prevent oxidization.
