South Asian Human Rights Documentation Centre (SAHRDC) is a non-governmental organisation which seeks to investigate, document and disseminate information about human rights. A small office with limited resources, the SAHRDC also runs an internship programme attracting scholars from universities in India and abroad. It required an office to be made on a 50 sqm plot emphasising spatial efficiency and cost effective construction.

Design Generators

STREET CORNER
The site is at a busy street corner with essentially pedestrian traffic. As the site is not very large, the acoustic and visual intrusion of the street activity into work spaces was a key concern.

CONSTRAINTS OF SPACE AND COSTS
The method of construction adopted had to optimize the space available on site and a modest budget.

SOLAR THERMAL GAIN
The orientation of the site is such that the longer 10m side is exposed to direct sun throughout the day. Reducing the resulting solar thermal gain was an important design generator.

Design response

ENGAGING THE STREET

Although some fortification against the street was required, it was crucial for the façade “converse” with the external activity. The external wall is conceived as an animated, dynamic skin reflecting the bustle of the street and activating what would otherwise have been a mundane façade with minimal fenestrations. The porosity of the wall maintains a degree of privacy while playfully engaging with the street corner.

SPACE AND COST OPTIMISATION:

Efficient Space utilisation is achieved by creating a single consolidated volume on each floor to be flexibly partitioned as per the client’s requirements. This volume is serviced by a flanking buffer bay of a single flight cantilevered staircase and a toilet stack. Costs were minimised by using exposed brick construction and by creating a beamless soffit at every floor.

To create a beamless soffit without increasing the thickness of the slab, a gently vaulting roof was designed. Lateral inverted beams were introduced and flooring laid onto an infill so that each floor plate insulated eliminating the need for a false ceiling.

BREATHING THERMAL BARRIER:

This buffer bay forms a breathing thermal barrier along the sun facing side. By situating the staircase and toilet stack in this bay, the internal workspaces are protected. The porosity of the wall ensures that the buffer bay is well ventilated and yet shaded so as to reduce the amount of heat transmitted to the workspaces. A single repeating brick module creates a visually complex pattern in the manner of traditional South Asian brise soleils.

The construction of the wall:

A six brick module is laid in staggered courses that create twirling vertical stacks and an undulating surface. The construction of the screen wall was a result of a five-week process devising masonry techniques on site. From verification of plumbline to the structural bonding of the brick courses, methods of brick laying were devised through a deep on-site collaboration between the masons and the architects.

There were four objectives that the construction of the screen wall was attempting to achieve:
High level of porosity in the central portion of the wall.

Effective horizontal bonding and load distribution between the bricks.
No visible intrusion of any material other than brick masonry onto the façade.
The repeating pattern modules must be complete end to end over the entire width and height of the wall i.e. there should be no deviation in the pattern.

Through computer modeling, the architects realized that a simple rotating module of bricks would create the kind of visual and textural complexity need to achieve the design objective of engaging the street corner.

To begin with a six brick module of bricks on edge was devised for the construction of the wall. This was so that the module would cubic in shape and therefore directionally inert. Bricks were laid on edge so that the voids created by missing bricks would substantially contribute to the porosity in the central portion.

But using a 6 brick module created to very basic masonry concerns:

For proper alignment (prevention of corbelling), all the centres of the modules in a vertical stack had to fall on one perfectly vertical axis around which the module would rotate. This was difficult to estimate accurately on site during bricklaying (owing to human errors).

The other issue was verification of plumbness of every course. Dropping an accurate plumb line from one course to the next was not feasible since the brick faces were not in the same plane.

A single vertical stack was built and rebuilt five times on site with both the architects and the masons trying to co-strategise on a simple and practical brick laying technique that could be replicated by the various masonry teams without relying heavily on the individual skills of a master mason.

The floor slabs were cast at floor-to-floor heights of 3180 mm. This was distributed over two sets of continuously repeating 6 module course patterns so that the 1st, 7th and 13th course are the same. A set of 6 individual course drawings were prepared in studio and the angle of rotation between them calculated. From these, sets of triangular wooden wedges were made and distributed amongst the masonry teams. They were used by the bricklayers to verify the orientation of the bricks while laying them.

The horizontal interlocking between modules essentially happens through the cross-stack overlapping of the central bricks in the modules. In the porous central portion of the façade, brickwork is reinforced horizontally by a laying a thin section (95mm X 125 mm) reinforced cement concrete beam along the cavity created by the missing central brick.

Final acceptance

The newest addition to IJburg can already be seen from the A10 interstate near exit 114 and has already been given a name: the xxx’s. A prominent and elegant building, formed by a diagonal grid covering the façades. From the interior or the balcony, a striking view across the water with the A10 as a background.

Process

3Years ago, BNB architects and B06 architect-firm took the initiative in self-developing an office building for their own use. The municipality gave them a 2 month option on a building plot on Steigereiland with a GFA capacity of 3500 m2. In this period a sketch design had to be drawn, 65% of letters of intent to be gathered and a financial plan had to be realised.

On their own, the two firms were good for 700 m2, thereby creating the idea of CBC. Anyone who decides to join becomes commissioner and is therefore able to participate in decisions and buys condominium at cost. Within 2 months, 8 end users had been found eager to participate in developing their own office, giving the option on the plot a follow-up.

It soon became clear that assistance in the group process was needed. The principle of CBC had never been tried before and therefore had to be invented, in organisation as well as law. For this, Lingotto real estate was hired as a delegated commissioner.

Building

The assignment laid out by the municipality required a universal icon. A search for an elegant not conspicuous way to make a distinctive building began. A sturdy, industrial and no-nonsense building. In the end the choice was made to rotate the window frames by about 45 degrees, crossed by diaphragm ribs creating a triangular pattern. This grid covers the entire façade. On a sunny day throughout the building an array of shadow-lines appears. The only exception is a cut-out at ground level accommodating the entrance.

Because the diaphragm ribs are situated outside of the façade an exciting view of lines is shown, changing from every angle you look at it. Also, the ribs are being reflected in the glass creating even more plasticity. Consulting façade builders Bos brothers from Goudriaan, Jatoba wood

(FSC certified) was chosen. The story high façade elements were prefabricated, the corners even in 3D. The wood was given a protective treatment once, against construction damage and will eventually turn grey. The carcass is built from steel columns and concrete floors, with floor heating and cooling. Even though it is a basic shell, all ducting has been hidden.

Floor plan

The floor-plan is also slightly unusual. The hall with void is parallel to the north facade, connecting 20 units, 5 on each floor. The wall between the hall and the units is entirely transparent creating an optimal view for everyone. Because of this situation all logistic movement in the building is visible giving it a life.

It also accommodates chance meetings and interaction between companies. Along the south side the wooden grid continues. However, the climatic shell has at this point been retracted for 1,5 meters, creating a fantastic balcony which also blocks part of the direct sunlight. In this part of the grid the only glass used is for protection at the edge.

All doors and windowframes are 3.3 meters tall, a choice which would be budgeted out in any standard building, but was received with enthusiasm by the commissioner association (CA) as was the balcony. An end user enjoys something extra.
