Alteration & Additions (A&A)

We have a strong track record of construction and engineering projects in Hong Kong, from single-storey construction to large-scale schemes including mixed-use development, multi-storey tenancy as well as iconic retail and hospitality destinations.

TCG have a strong track record of A&A Projects, as an experienced RGBC we have delivered complex high-rise extensions, façade improvements, commercial tower roof signage, lift shaft relocations and integrated high-end interior works for a complete solution.

TCG are experts in delivering complex solutions to an exceptional quality and pride ourselves on not just being builders but in sharing our customer’s vision: understanding, planning and being flexible to deliver a successful project with a can-do attitude closely along-side the consultant team.

With our roots in fit out, it is not surprising that TCG is trusted with some of the most complex refurbishments, restorations and retrofit projects as well as traditional new build construction projects.

We never shy away from tight programmes and logistical complexities. We understand that delivering large projects is not just about square footage or scale; it’s also about being entrusted with a big responsibility to make big ideas come to life.


When it comes to refurbishing or alteration and addition works, TCG is one of the most respected and active specialist contractors. We have delivered numerous complex refurbishments, often in occupied buildings. We have a strong track record in transforming tired and unproductive real estate into vibrant and inviting spaces, always meeting both the developer and tenants’ needs.


With extensive experience working with conservation bodies and funding organisations, we are proud to have been trusted to restore many prestigious and listed builds that boast rich histories. From straightforward to complex structural alterations, our expertise within listed and heritage environments means that we are able to craft intelligent and dynamic solutions to meet the needs of each individual customer.


TCG understand that a sustainable approach to development, retrofitting and reusing as much of the fabric of the original building wherever possible, is good for both our customer’s bottom line and the environment. We have an enviable track record in bringing older stock  up to the latest environmental standards, and have delivered numerous retrofit projects throughout Hong Kong.
