德勤集团自 2013 年成立以来，历经十余年深耕，旗下已形成 “深圳市德勤建工集团有限公司” 与 “深圳市德勤四季控股管理有限公司” 两大核心子公司，业务版图横跨建筑设计、施工、消防、空调、弱电、安防智能一体化，及产业园投资运营、产业孵化、商业空间运营、物业管理、企业服务等多元领域，现已成长为大型综合性服务集团。

集团创立之初，便携手灵信设计展开品牌整体塑造。以 “用诚信构建经典，以勤勉铸造非凡” 为核心企业理念，这一理念既凝练了品牌服务的态度，更锚定了长期发展的目标。品牌创意围绕这一理念延伸 —— 以 DQ 字母环绕造型，具象化 360 度全方位服务的承诺，既深度呼应企业理念，更强化与客户的深度对话，让专业服务与品牌初心形成共振。

Since its establishment in 2013, Deloitte Touche Tohmatsu has, after more than a decade of development, grown into two core subsidiaries: Shenzhen Deloitte Construction Group Co., Ltd. and Shenzhen Deloitte Four Seasons Holdings Management Co., Ltd. Its business scope spans diverse areas, including architectural design, construction, fire protection, air conditioning, low-voltage electrical systems, and integrated security solutions, as well as industrial park investment and operation, industry incubation, commercial space operations, property management, and corporate services. It has now grown into a large, comprehensive service group.

Since its inception, the group has partnered with Lingxin Design to develop its overall brand. Its core corporate philosophy, "Building classics with integrity and creating excellence with diligence," embodies the brand's service approach and anchors its long-term development goals. The brand's creative design revolves around this concept—the DQ logo encircles the design, embodying the company's commitment to 360-degree service. This not only deeply resonates with the company's philosophy, but also strengthens in-depth dialogue with clients, resonating professional service with the brand's core values.
