140 Wireless Road

A grade ’A’ office development right next to Bangkok’s central
Lumpini Park. The development consists of double glazed office
spaces shaded by horizontal set backs and vertical elliptical
aluminium fins with integrated draiange. The offices link to an
exisiting office building at lower levels.


140 Wireless Road

The rooftop levels house MEP equipment and an ultra luxury whole floor single residence with an outdoor pool.

The facade system of the office consists of a simple strip window system sitting on a low upstand creating a less intimidating more relaxed edge interface.

The multi part vertical aluminium fins are constructed fromnmultiple extrusions mounted onto a steel box frame. Every eighth fin contains a concealed rainwater downpipe and floor drain routing water from the shading terraces. The pipes can be accessed by hinged extruded door elements integrated into the fins.

The glazing is a double glazed unit with a neutral double silver low-e coating with medium external reflectivity. At level 14 a highly transparent intermediate floor uses ultra clear low-iron glass with a triple silver low-e coating and wider module width to enhance views around the city.

The bottom two floors of the podium are for retail usage and enclosed with the same ultra clear glass as level 14 but captured in a semi-unitised steel reinforced stick system to enable the double height span of the space which has a mezzanine floor and spiral staircase.

The transitions between podium to office and office to level 14 are handled with large grey cement GFRC panels painted to match the aluminium fins.

Access for maintenance is handled by access doors to every terrace level and anchor points for rope access technicians. Vertical drops such as the curtain wall strips at the sides of the building are accessed by using openable windows in the facade to hang gondolas or to abseil from (look closely at photo below).

The simple form, clean detailing and limited materials pallette create a sophisticated addition to this corner of Lumpini Park
