Stellar Structures

At a Glance

Stellar Structures uses drone technology for periodic façade inspections, capturing imagery and measured data for building condition assessments. The platform supports authority submissions across BCA, URA, HDB, JTC, SCDF, PUB, LTA, NEA, and NParks for Singapore projects. The company reports over 20 years of industry experience and a client focus on safety and cost control.

Core Features

The software combines engineering, architectural, and interior design workflows with inspection management and submission tracking. It links drone inspections and 3D modeling outputs to structured inspection reports, and it stores documentation needed for authority approvals. The tool also manages structural and geotechnical consulting records and façade design files using materials such as aluminum composite panel, stone, glass, and metal cladding.

Key Differentiator

Integration of drone technology for façade inspections with direct support for authority submission workflows. Inspection imagery and measured data feed into permit and approval packages within the same project workspace. That approach reduces administrative handoffs between inspection teams and submission coordinators.

Pros

The platform is backed by an experienced team with over 20 years of practice across residential, commercial, industrial, and infrastructure projects, which helps translate regulatory requirements into practical deliverables. It covers the full lifecycle from inspection and design to authority submission, combining structural and geotechnical consultancy with façade engineering and interior design. The vendor advertises a high approval success rate of about 99%, and the system’s collaboration features support work with architects, contractors, and government agencies.

Cons

• Pricing is not fixed and depends on project complexity and scope, so you must request a project-specific quote before budgeting.

Who It’s For

Property developers, building managers, architects, engineers, and contractors in Singapore who need an inspection and submission workflow tied to local regulations. Teams requiring façade inspections, structural checks, and packaged authority submissions will find the platform relevant. It is less suitable for projects outside Singapore due to jurisdiction limits.

Unique Value Proposition

Consolidates inspection imagery, measured data, and submission documents in a single project environment so teams can assemble approval-ready packages without moving files between disparate systems. That consolidation shortens the review cycle for permit documentation and clarifies responsibilities across consultants. The efficiency gain applies directly to projects that must meet multiple agency requirements in Singapore.

Real World Use Case

A property developer schedules periodic façade inspections using drone flights managed in the platform. The inspection output is annotated, converted into repair specifications, and then combined with structural calculations and drawings for submission. The team uses the same workspace to coordinate repairs and file approvals with the relevant agencies.

Pricing

Pricing is not published online and is quoted per project. Costs vary with project type, building height, scope of inspections, and the extent of submission work required. Requesting a scoped proposal and fee estimate is required to obtain firm pricing.

CPG Corporation

At a Glance

The company traces its history to 1833, an unusually long institutional record for an urban development advisor. It has played roles in projects such as Changi Airport and Gardens by the Bay. The profile emphasizes sustainability, resilience, and multidisciplinary delivery for large urban projects.

Core Features

CPG Corporation combines multidisciplinary design and engineering with development management and facilities management to support projects from planning through operations. The offering highlights sustainable and resilient urban development practices and includes investment and property development capabilities. These elements work together for clients needing integrated advisory and long term asset management.

Key Differentiator

The defining attribute is the blend of an extended institutional legacy with explicit emphasis on sustainable resilient design across multiple regions. That historical depth informs a broad bench of expertise in city scale projects and landmark developments. This angle suits clients that require continuity of knowledge across planning, construction, and facilities operations.

Pros

The organisation delivers end to end services that reduce the need to coordinate separate consultants across planning, delivery, and asset management.

The emphasis on sustainability and resilience aligns with contemporary regulatory and climate adaptation needs for city level projects. High profile landmark involvement provides case references for complex technical and planning challenges.

Cons

• Limited public product detail: specific service packages, workflows, and deliverables are not listed on the homepage.

• No explicit pricing: fees are likely project based and bespoke, which complicates early-stage budgeting.

• Primarily large scale: the focus on urban and infrastructure projects reduces relevance for small sites or individual homeowners.

When It May Not Fit

This option is not appropriate for small scale renovations or single house projects that need fast fixed fees. It does not present modular service packages for quick procurement by small contractors. Teams seeking a pure software tool for project management or lightweight design checks will find the offering oriented to consultancy and asset management rather than packaged software products.

Who It’s For

Government agencies, city planners, and large institutional clients requiring integrated urban infrastructure advisory will find the profile relevant. Developers that manage large mixed use or public realm projects benefit from the combination of planning, construction management, and long term facilities capability. Clients seeking direct investment or asset management partners will also match the stated capabilities.

Real World Use Case

CPG supported the design and delivery of Bidadari Park with integrated ecological and cultural features and resilience measures. The engagement spanned concept planning, detailed design coordination, and arrangements for long term maintenance.

When It May Not Fit

Clients that require immediate construction delivery or fast budget-driven fixes will find the consultancy model a poor match. That pace mismatch also applies to small renovations where a lighter local practice offers faster procurement. Organizations seeking software tools or productized services should look elsewhere because DP Architects operates as a professional design practice.

Who It’s For

Institutional clients, government agencies, and private developers seeking a high-quality architectural and urban planning consultancy. Project teams that value documented research, formal design validation, and visible award credentials. Clients planning large public or cultural projects that require stakeholder coordination and long-range planning.

Core Features

The practice delivers design leadership for large scale urban, commercial, residential, cultural, and institutional projects, with specific experience in Singapore’s central business district. The team combines project delivery for complex developments with a focus on sustainable and practical design solutions. Architects 61 also runs community outreach and industry engagement programs that support professional development and public dialogue.

Key Differentiator

A longstanding presence in Singapore and a portfolio of iconic, award winning developments set Architects 61 apart from smaller firms. That track record means the firm has institutional experience with master planning, multi stakeholder coordination, and authority submissions typical of major downtown projects. The firm therefore serves clients needing visible, cityshaping architecture.

Pros

Architects 61 brings deep expertise on complex urban projects and a leadership team with seasoned architects who have delivered landmark buildings. The firm has received awards and international recognition that support its design credibility. It also demonstrates a sustained commitment to sustainability and to community and educational initiatives, which helps clients meet public engagement and corporate responsibility goals.

Cons

• The firm focuses on large scale and landmark projects. It may not be the best match for clients seeking only small scale residential remodels.

• Very small or highly specialized niche projects could require a different firm with that exact expertise.

• The public information does not list fee structures or detailed pricing, which complicates early budget planning.

Who It’s For

Large developers, government agencies, and institutional clients seeking high profile architectural leadership in Singapore will find Architects 61 appropriate. The firm fits clients who require experience with complex approvals, multi party coordination, and projects that aim to shape the public realm. Private clients with modest, single home briefs will likely find the firm oversized for their needs.

Real World Use Case

A developer hiring Architects 61 for a mixed use tower receives design leadership through schematic design and authority submissions for downtown sites. The firm applies its CBD experience to massing, facade strategy, and public realm interfaces. That approach reduces coordination friction with agencies and aligns design intent with urban requirements.
