Saudi Arabia Lastoria Mall Design Project-1783050826313934
The project is a mixed-use commercial development comprising retail buildings, service facilities, and a public plaza in Saudi Arabia. Located along a major commercial corridor with direct access to key city arterials, including King Abdullah Road and King Fahd Road, the development forms part of a well-connected urban commercial district.
PRANCE was engaged to develop original façade design concepts and provide detailed cost estimation for each design option, covering the metal façade system, glass curtain wall system, selected structural and roof interface works, and railing systems across multiple buildings within the development.

| Client Design Requirement
The owner of Lastoria Mall had already engaged multiple local design consultants for the project. However, the provided designs were too similar to other local shopping malls, lacking a distinctive architectural identity. The client therefore sought a more unique and refined design solution and came to PRANCE for something special.
1. Establish a Unified Brand-Driven Architectural Identity
The design introduces a consistent architectural direction across the development, balancing overall unity with clear individual identities for each building. The design moves away from generic local references and aims to establish a more distinctive visual identity for the shopping mall.
2. Design Facades with Different Building Functions
The façade design needed to consider the different service building functions within this development. Each façade solution was required to reflect its functional role while remaining consistent within the overall architectural system.
3. Distinctive Design with Cost Evaluation
The client required PRANCE to develop multiple design proposals for the shopping mall, each presenting a distinct architectural direction with a corresponding cost estimate to support direct comparison of design intent, aesthetics, and budget implications.
| Design Development and Concept Refinement
Proposal 1: 6 Different Design Options
In the first proposal, six different design options were developed. The visualizations were closely aligned with the actual building structure, allowing each concept to be evaluated in a more realistic project context.
According to the initial requirements, the main building façade integrated the Lastoria logo and supported ventilation requirements for balcony areas. The elevator area was designed with a curtain wall system to enhance visual transparency. Other design options incorporated curved lines. Following the review, the client clearly expressed a preference for a clean, linear aesthetic and a box-like building design.
Proposal 2: Design Refinement
Based on the feedback, PRANCE design team refined the design. For the second proposal, we provided three revised options, which focused more on functionality and brand expression. We also used multiple perspectives to communicate the design proposals more clearly.
Design Refinement and Cost Optimization
Although the second proposal was well received, the overall cost exceeded the expected budget range. A further refinement process was therefore carried out, focusing on simplifying selected façade areas while maintaining the core design intent.
Integrated Design for Surrounding Area
Following the confirmation of the main building façade design, we extended the design scope to the surrounding environmental elements, including landscape integration, pedestrian walkways, column cladding, terrace areas, railing systems, etc. This integrated approach helped create a more continuous visual and spatial experience throughout the development.
| PRANCE Tailored design: final version
Through iterative design refinement and cost optimization, the final scheme was developed and confirmed.
1. Unified Façade System with Differentiated Building Design
The façade design uses a coordinated system of stone-textured aluminum panels, glass curtain walls, and aluminum cladding to create visual consistency across the shopping complex. While the overall style remains unified, each building is given room for its own identity within the wider composition.
Some key buildings are treated with more specific façade expressions based on their functions. The mosque building incorporates decorative patterned and more open façade elements to reinforce its cultural character. The building A introduces a large architectural opening that integrates signage and increases its presence within the overall composition.
2. Spatial Experience and Surrounding Area Design
The pedestrian link bridge and terrace areas extend the architectural language into the public realm. Continuous material treatment along the link bridge creates a cohesive visual experience, while transparent glass railings on terraces preserve openness and unobstructed views. Selected zones introduce modular dome structures, adding functional flexibility and a distinctive spatial character to outdoor areas.
4. Material Selection and Cost Budget Control
A cost-efficient façade strategy is achieved through the use of stone-textured aluminum panels, allowing a consistent stone-like appearance across large areas while reducing reliance on natural stone. Glass and aluminum systems are applied in secondary zones to maintain balance between visual consistency, performance, and budget control.
| PRANCE Integrated Solution
PRANCE's integrated design service scope covered original façade design development and detailed cost estimation across multiple design directions. This allowed design options and budget implications to be assessed in parallel during the decision-making process.
Beyond the design stage, PRANCE can also coordinate product supply and provide on-site installation guidance, maintaining continuity across the entire workflow. This ensured alignment between design intent, cost control, and on-site execution from concept through to delivery.
