TCA Design and Build is a design-led design-and-build studio in Singapore specialising in landed homes, including rebuilds, Additions & Alterations (A&A), Good Class Bungalows (GCBs), and concrete, civil and structural works. The studio is led by Pier Alessio Rizzardi, Principal Builder and an educator at the National University of Singapore, who brings a decade of experience in Singapore's landed home market.
TCA positions itself around an in-house, single-team model: clients deal directly with Pier as founder, with design, cost, time and quality control kept in-house rather than outsourced through subcontracted layers. The team is on site daily, and states it works to clear, upfront pricing without hidden extras.
Services span the full project lifecycle — feasibility and GFA analysis, integrated design, coordination of statutory submissions with URA, BCA, SCDF, PUB and NEA through partner Qualified Persons and Professional Engineers, structural works, interior design, and construction through to TOP coordination. TCA is a BCA-certified builder working on terrace, semi-detached and bungalow projects, and also offers a metal works and loft specialist service. After handover, the studio provides structured defect liability coverage for workmanship-related issues within the agreed period.
TCA is part of the wider TCA Think Tank network, which also includes TCA Think Tank Workshop (interior design and construction), TCA Think Tank Editions (architecture publishing) and TCA Think Tank Gallery (custom handcrafted design work).
TCA Design and Build is a Singapore-based design-and-build studio focused specifically on landed homes — terraces, semi-detached houses, bungalows, and Good Class Bungalows (GCBs). The studio's approach centres on keeping design, engineering and construction under one accountable team, rather than splitting the work across multiple separate contractors.
At the centre of TCA is Pier Alessio Rizzardi, the studio's Principal Builder, who also works as an educator at the National University of Singapore. With a decade in Singapore's landed home market, Pier's work spans rebuilds, A&A projects and full landed home builds, coordinating everything from GFA planning and structural sequencing to materials selection and final execution. Clients dealing with TCA work directly with Pier rather than through layers of subcontractors or account managers.
TCA describes its model as fully in-house: the studio does not outsource, meaning cost, time and quality are controlled directly rather than handed off. The team is on site every day, and TCA states its pricing is clear and upfront, without hidden extras. This hands-on execution, without middle layers, is presented as central to how the studio operates.
The studio's core work covers Good Class Bungalows, full rebuilds and reconstructions, Additions & Alterations (A&A), and concrete, civil and structural works. Project timelines vary by scope — A&A projects typically take around 6 to 8 months, while a full rebuild generally runs 12 to 18 months, reflecting the added complexity of ground-up construction.
TCA's portfolio includes a range of completed landed projects, among them the Ong Bungalow (1,060sqm), Guillaume Villa (485sqm), Leow Terrace (520sqm), Khoo Terrace (440sqm), Baptiste Villa (275sqm), Lim Terrace (430sqm), Vee Terrace (365sqm), Goh Terrace (470sqm) and BB Bungalow (665sqm) — spanning bungalows and semi-detached homes across Singapore.
Landed construction in Singapore involves navigating several regulatory bodies, and TCA coordinates statutory submissions and approvals with URA, BCA, SCDF, PUB and NEA. These submissions are executed through TCA's network of collaborating Qualified Persons (QPs) and Professional Engineers (PEs), who retain professional responsibility for compliance with Singapore's statutory requirements.
TCA works from a detailed cost framework aligned to a client's target budget from the outset, with design decisions controlled against that framework and structured cost updates provided along the way. Pricing itself is tailored to project size, technical complexity, material selection and level of customisation, so smaller renovation works are quoted differently from bespoke landed rebuilds.
Once a project is handed over, TCA provides structured defect liability coverage, rectifying workmanship-related defects identified within the agreed period after completion.
TCA operates as part of a wider network under the TCA Think Tank name, which also includes TCA Think Tank Workshop for interior design and construction, TCA Think Tank Editions for architecture publishing, and TCA Think Tank Gallery, a boutique design lab producing custom handcrafted artwork, movie sets, props and event setups.
For homeowners considering a landed rebuild, an A&A project, or a bespoke Good Class Bungalow, TCA positions itself as a single accountable partner covering design, engineering, statutory approval and construction from first consultation through to handover.
