Dream Computer Room

One of my latest projects for my MEd, required me to design a computer lab. I had a budget of $45,000 and it had to accommodate 30 learners. My total, outlined in more detail below, came in at just under budget, at $44,171.90 - and goes against the grain of the traditional lab design.

Having had the luxury of re-designing and implementing a new classroom design whilst working in Singapore (see any posts regarding The Octopus's Garden Project, and photos in posts from 2013-2014 in particular) I already had a few ideas that meant I very much wanted to move away from a traditional layout. 

For more inspiration, I asked for the dream design of educators I have worked with in different countries and different schools. What was interesting to me, was those who have worked in tehnology-rich environments, where the idea of a dedicated computer lab is outdated and technology infuses everyday learning, had many more suggestions that broke the mould of lab design and fitted with my own. Many thanks in particular to Marcus and Ed - I miss you guys - as well as my hubby.


Instructional Purpose

The design of this computer lab challenges the status quo offering an up-to-date multi-functioning, highly flexible interactive space. Too often, “institutions give little thought to the design and layout of the lab…they simply fill a room with computers and set up the machines any way they fit inside the room” (Garger, 2011); a mind-shift in how we view learning spaces manifests in a requirement to “renovate or repurpose classrooms to address the needs of the future…through the concept of Makerspaces” (Smith, 2015). The purpose of this room is to move beyond merely using technology to begin controlling it – in short, to start “tinkering” (Stager & Martinez, 2013). As the requirements are to accommodate 30 learners, the requisite number of devices is available in a mixture of iPad Airs, Dell Chromebooks, iMacs and a HP Sprout. There is no designated ‘front’ of the room, as the whole space is designed to be re-purposed according to needs - the majority of desks and tables are mobile and on castors, laptop tables are foldable and portable, tables can be placed in different configurations in terms of height, and chairs, sofas, and beanbags are either stackable or moveable. Storage is available to accommodate all learners’ bags keeping them out of the way for safety and additional work space.

Five beanbags, five rugs, three sofas, ten lap-tables, ten tablet-stands and ten stand-up laptop tables are versatile equipment that will allow learners choice in how they work – sitting alone, collaborating in groups, on the floor, or standing up. Small tables on castors can be moved as needed and house the printers and document camera. The Bekant tables can be adjusted “electrically from 22" to 48" to ensure an ergonomic working position” (IKEA, 2015) and the Niselrik stools are also adaptable to meet the heights of the tables – seating a total of twelve. A conference table seats ten allowing for large group work, whilst six iMac computers are housed in pairs on UXL tables that come equipped with “locking casters for easy mobility” (Demco, Inc., 2015). A ‘teacher’ desk and chair is home to the HP Sprout however, it is not exclusively for the teacher’s use. Once the teacher has taken the register, demonstrated and modelled, the Sprout is available for use by anyone. Indeed, the teacher may decide to use a laptop or tablet to model and take role, as the network and projector set-up allows for all devices to connect.

Three wall-mounted charging cabinets of twelve slots each can “mix and match mini-laptops, tablets, and hand-helds for even more flexibility” (Ergotron Inc., 2015) and are chosen not only because the lab is open for whole-school use meaning portable trolleys are not required, they also maximise floor space. Two Epson interactive projectors with “wireless networking” and an “interactive pen” (Projector Central, 2015) offer connectivity on a number of devices meaning all learners can connect and share work easily, and are mounted on the ceiling at opposite ends of the room adding to the idea that there is no designated ‘front’ of the room. A whiteboard is not included in the design instead Idea Paint is an up-to-date alternative. Idea Paint makes surfaces work like a whiteboard meaning the whole room can become a scribble space. Enough has been included in the budget to paint the majority of the walls (less the windows, door and top section of the walls that are out of reach) as well as some of the tabletops. The necessary materials to use the surfaces effectively have been included in the budget. Black-out blinds are fitted to the windows to allow maximised viewing and five floor lamps mean that ambient lighting keeps the space lit yet homely creating a nurturing and safe environment for experimentation. The design outlined in the images below (see Figs. 1-3) show only one possible layout for the room.


A blend of technologies is used in this lab to offer the widest and most flexible use and exploration of the power of technology on learning – this includes desktops, tablets, laptops, 3D scanners, interactive projectors and printers - all of which have been chosen for their ability to work with a variety of devices allowing this design to be realised. Relevant extended warranty and/or service agreements are also included within the budget.

Six iMacs provide exceptional desktop power particularly in terms of editing and creating films, podcasts and music. Apple products do not require additional virus software meaning that, whilst they can be more expensive than PCs, they offer advanced security at no additional cost. In addition, Apple offers an educational discount. The 21.5-inch screens with 16GB of RAM and 1TB of storage are chosen, as the school is opting for use of Google Apps for Education (GAFE), which offers “unlimited storage” for schools (Google, 2015). Each machine comes with a magic mouse or track-pad (I would order three of each to offer choice) and wireless keyboard (Apple, Inc., 2015). Insignia mono-headphone sets that are ‘”compatible with most cell phones, tablets and other devices” are available for each learner allowing them to be able to focus on the room and their work simultaneously; these include a microphone with “noise cancellation” (Best Buy, 2015). In addition to the six desktops, there are 15 iPad Airs and 15 Dell Chromebooks – meaning there are more than enough machines available for everyone in the room, including the teacher. These can be charged when not in use in one of the three wall mounted cabinets.

Fifteen Dell 11 i3 Chromebooks have “no problem working with more than 15 open tabs at once” and also lasted “more than 10 hours 0n the Laptop Mag Battery Test” (Spoonauer, 2015). The option on the budget comes with a “rubberized LCD and base trim” that “absorbs shock for superior drop protection” and is “U.S. Military Standard tested for durability, pressure, temperature, humidity, shock and vibration so it can handle the unpredictable” – namely, a classroom full of students (Dell Chromebook 11, 2015). As Chromebooks allow connectivity to GAFE, these are an affordable and workable option for the classroom particularly as there is also the option of using one of the iMacs, the HP Sprout or on the of the iPad Airs for more advanced requirements.

The iPad Air has been chosen as it is light-weight yet has the large screen, and with an in-built camera, can operate as a film recorder. Three Structure sensors along with the requisite ‘launch bundle’ will mean that learners can that attach the scanner and “wirelessly stream 3D scans…in real-time” where “the 3D printer can be accessed wirelessly to print out designs” (Occipital Inc., 2015). Installation of a 3D printer and a HP Sprout into this flexible space allows for the creation of a ‘makerspace’ where learners who can “create tangible portfolio pieces may find their work of interest to future employers” (EduCause, 2013). This emerging technology would be housed on a ‘teacher desk’ with chair, as more supervision may be required. The Dremel 3D printer is recommended for use with the HP Sprout but also connects to the iPads for use with the Structure sensors. 3D printers are new in education but offer a large scope across the curriculum (see infographic, 3dprintingsystems, 2014). A regular printer that connects wirelessly to all devices is also available along with two projectors that are mounted on the ceilings at opposite walls meaning learners do not have to be seated to face the ‘front’. In addition, a document camera is also available and all of this equipment can be accessed by via WIFI and from a variety of devices. An Apple TV enhances this capability for the Airs and the iMacs.


A dedicated ICT teacher is roomed within the lab but it can also be booked for other teachers to use as and when required and available. Training is provided to all staff via in-house sessions delivered by the ICT department and a member of the department remains in or near the room for support as required.

Server Hardware & Network

The school provides the server. It is located within the ICT department and has been installed and updated to cover the requirements of the entire school. Login for each learner is via the GAFE accounts administrated by the ICT department. A wireless router provides the WIFI within the room which is linked to the school server that controls and monitors web-browsing for the safety of the learners and in accordance with the state and school requirements. An Airport Extreme boosts and ensures a strong signal and optimised connectivity.


The budget allocated for this Computer lab, was $45,000. The total spend for the above outlined comes in just under budget, at $44,171.90. A full breakdown of costs is below (prices correct as at July 2015):

This design was created on Homestyler (Autodesk Inc., 2015) and annotated using Skitch (plasq.com, 2015). Due to limitations in the software, some items are either not to scale or not as described but the correct size. The room is the exact measurements of one of the ICT labs at my current school. In all cases, the closest possible matches in terms of size have been used. Not included: stand-up tables, printers, laptop- or tablet-stands. This is only one of many possible layout designs.
