01 THE INTERGENERATIONAL OFFICE

Designing an Architectural Office for all ages for cooperative design

Today, architecture firms in general are seen as the ‘gifted few that design for the whole’ and are usually designed by firms consisting of similar ages. Children and the elderly are the minority and are often unheard in the design world. The project aims to combine the minds of children and elderly, which can benefit and dispel the need for ‘homogonous practices’.

INTERGENERATION DESIGN DESIGN THROUGH PLAY

THE SOCIAL LIFE

The project explores how an architectural practice can create spaces that improves the interactions between architects, children and the elderly. The programme flowers into a playful landscape which utilises colour theory, landscaping and natural materials to enhance the user experience and intergenerational interaction within the practice. This approach creates a series of spaces that encourage architects to engage with the building and its other occupants, which in turn allow architects make more meaningful and well thought out projects for children and elderly.

02 THE OPEN CITADEL

- Designing a cultural hub for local people to preserve their local activities -

Hong Kong has rapidly grown into an urban city over the past 100 years; however, this rapid urbanisation threatens the existence of cultural sites. As a response to the theme ‘Citadel’, the project aims to protect cultural sites from gentrification by preserving the site’s identity. This project explores how architecture can perverse cultural activities and raise awareness of the importance of heritage sites.

The site is located in Nim shue wan, Hong Kong – a small village which sits next to urban development. The programme is called an ‘Open Citadel’. It consists of a series of structures that aim to celebrate and house cultural and agricultural activities that are unique to the site – outdoor cooking, dining, farming, recycling and fishing. The facilities will mainly be used by locals, but it also provides services to passing tourists and charity workers.

The buildings are designed to fit into the landscape while also being aware of its lifespan. These structures are temporary. Overtime, they can be stripped away, leaving only its footprints

Nim Shue Wan is comprised of networks which fuel their activities and create their identity. Many of these activities are agricultural such as fishing, cooking and farming crops.

03 ALFRED PLACE - BEN ADAMS ARCHITECTS

An office refurbishment project set in the heart of Bloomsbury

PROJECT BRIEF:

Located in the heart of Bloomsbury, Alfred Place was a project that aimed to transform an existing office into a high end and sustainably accredited scheme. The project consisted on 7 floors, including the basement and a new roof extension to replace the empty roof.

Following a previous refurbishment in 2016, the project aims to update the building to meet the requirements of Great Portland Estates.

MAIN RESPONSIBILITIES :

Developing construction details for mainly interior bespoke designs

Coordinating roof arrangements and sections with structural engineers / external consultants

Producing presentations for Design Team Meetings for smooth communication and documentation

Executed layout designs for all floor in conjunction with RCPs ( reflected ceiling plans)

04 SELF-SHADING FACADES

By using computational methods within LLMs, Sign Distance Fields & 3D Printing techniques

This project was created from the perspective of Architectural Computation. Therefore this project focuses on finding optimal shapes to reduce thermal exposure in facade bricks using a technique called ‘Sign-Distance Field’. In collaboration with two other members, a unique workflow was tried and tested. This workflow challenged itself to use Large Language Models to create the base shapes, where this information was fed into the Sign-Distance Field algorithm to create a 3D proposal. Finally, the shape produced was 3D printed in a simulated environment and tested using LadyBug (Grasshopper) to ascertain if the design performed better than regular bricks. Although, this portfolio showcases only my contribution to the workflow - finding optimal facade for different orientations.

SIGN - DISTANCE - FIELD :

EXAMPLE ITERATIONS + TESTING

- A signed distance function/field (SDF) as a 3D shape description is one of the most effective approaches to represent 3D geometry for rendering and reconstruction. The algorithmic method consists of two planes (top & bottom) where a simple set of lines drawn by a user can create complex 3D contoured shapesY

SDF FIELD – BOTTOM FIELD

SOUTH EAST & SOUTH FACADE DESIGNS :

- These two orientations were chosen to focus on as they recieve the most intensive lighting during the day. The results below showcase the percentage of shading per block. Hence, the higher the score, the better

DESIGN DECISIONS BASED ON SIMULATION TESTING :

- Based from simulation testing from multiple parameters such as height, angle and thickness (more on previous page), the best performing parameters where selected and combined together to create the ‘optimal self-shading facade block

05 AGENT LAYOUTS

Architectural Layout Generation using computational methods

This project explored the idea of using ‘Agent-Based Modeling’ to create unique floorplans based on preferences from users. The initial brief of the project was an office located in central London. Initially, a general shape was produced by a user, and the project wanted to work out how the arrangement of different plans changed based on view and sun qualities.

Next, a custom made plugin was created to calculate the thermal hotspots and view quality within the floorplan in which this analysis informed the rules of the agents. Such agents were assigned a ‘target’ to find, whether it would be a cold, visually less appealing areas for toilets or warmer, visually stunning areas for meeting rooms.

THE CREATION OF A BUILDING ON A SITE

06 THESIS : AGENT MODELS TO PREDICT CRIME

Investigating the validity & application of the ‘Theory of Visual Access & Exposure’ in Theft Spot identification using multiple agents - IN PROGRESS

Many studies of theft crime have been addressed for several years. Still to this day, the main challenge has been understanding fully the movements of offenders when considering their next victims. Recent research has included a focus on ‘hot spot/street detection’ where there has been a surge in interest in gaining a higher precision of where theft occurs. In doing so, law enforcement could better organize their resources for a higher payoff.

Agent-based modeling has been one method in destecting theft and it has been used in many crime prediction studies. The methodology used in computer simulation that concentrates on individual-level behaviors and is ideally suited to modelling crime. This is particularly true of crimes, such as burglary or street crime, which are heavily influenced by environmental factors and by the behavior of individual people.

When looking into the realm of space and criminal behavior, one key study has theorized and tested how offenders behave in enclosed spaces. John C. Archea (an architecture professor at State University of New York) theorized the concept of ‘Visual Access & Exposure’, arguing and proving that offenders in enclosed spaces position themselves to have maximum access and minimum exposure. The study was conducted in bank lobbies and by interviewing/simulating the movements of ex-robbers.

Although such studies have rarely implemented this specific theory on a larger scale, outside of an enclosed area such as a bank lobby or a small group of apartment blocks. Therefore, there are opportunities to investigate how Archea’s theory hold up in a larger urban environment. In doing so, the study would draw up the effectiveness and validity of the theory, providing any insight of any gaps in the theory if necessary.

Also as of now, Archea’s theory does not explicitly mention the role of bystanders/other pedestrians as guardians and variables in visual access & exposure.
