Why Building an Extension in Jeddah Is a Smart Solution
- More space without a full extra floor: add a room, majlis or living area without major structural changes.
- Cost-effective: much cheaper than building an entire new floor – especially with sandwich panel systems.
- Flexible design: we can design the extension as a bedroom, family hall, games room, office or staff unit.
- Fast execution: sandwich panel extensions are completed in a much shorter time than traditional masonry.
- Roof or yard options: build in the yard or on the roof after checking structural load and waterproofing.
- Better insulation (with sandwich panel): high thermal and sound insulation, ideal for Jeddah’s heat.
- Adds property value: a well-finished extension increases the resale and rental value of your villa or house.
- Future expansion: you can later add a bathroom, store or extra space with limited demolition.
- Multiple finish levels: choose from economic, standard or luxury finishes depending on your budget.
- Project management from A–Z: we handle everything from idea and site visit to handover with technical supervision.
Building Systems & Materials Used in Extensions
We offer two main construction systems and can combine them if needed:
- Traditional masonry extension: block walls, plaster, waterproofing, thermal insulation, and high-quality paints
for a solid and classic feel. - Sandwich panel extension: insulated steel panels that are light in weight, quick to install and provide
strong thermal and acoustic insulation.
Many clients prefer a hybrid solution – structural block walls where needed and sandwich panel roofs or partitions
to get the best balance between appearance, weight and insulation.
How We Execute Your Extension Project – Step by Step
- Site visit & needs analysis: we inspect the roof or yard and discuss how you want to use the extension.
- Choosing the best type: traditional extension, sandwich panel, or a mix of both – based on budget and usage.
- Detailed quotation: clear prices, materials, approximate duration and suggested finish level.
- Structure & preparation: building foundations or steel structure, and preparing the roof or yard.
- Walls & roof: installing blocks or sandwich panels, doors, windows and structural elements.
- Finishing: plaster, tiles, ceilings, paints, lighting and final details according to the agreed level.
- Handover & guarantee: technical inspection, handover to the client and clarification of warranty terms.

Sandwich Panel Roofs in Jeddah – Strong Insulation for Extensions & Buildings
Sandwich panel roofs are one of the best roofing and insulation solutions in Jeddah due to the high
temperatures and direct sun exposure. Sandwich Panel Jeddah Contracting uses high-quality insulated panels
to build strong, lightweight and weather-resistant roofs with professional detailing and slope design.
✔ What is a sandwich panel roof?
It is a composite panel consisting of three layers:
top steel sheet + thermal core (PU / PIR / EPS) + bottom steel sheet.
This makes it ideal for roofs of villas, warehouses, hangars and extensions.
✔ Key advantages
- Excellent thermal insulation, significantly reducing roof heat.
- Much lighter than concrete roofs – safer for existing structures.
- Rust- and moisture-resistant coated steel sheets.
- Fast installation compared to traditional systems.
- Easy to create slopes for rain-water drainage.
- Good acoustic performance in residential and industrial uses.
✔ Typical thicknesses and uses
| Thickness | Recommended Use | Insulation Level |
|---|---|---|
| 3 cm | Small or temporary rooms | Light insulation |
| 5 cm | Extensions & residential use | Medium insulation |
| 7.5 cm | Warehouses & hangars | High insulation |
| 10 cm | Cold rooms & freezing rooms | Very high insulation |
Roof pricing depends on panel thickness, core type, steel quality and supporting steel structure, but in many
cases the cost ranges roughly between 120–180 SAR per m² for full supply and installation, depending on final
specifications.

Frequently Asked Questions – Extensions & Sandwich Panel in Jeddah
How long does it take to build an extension in Jeddah?
A sandwich panel extension can be completed within a few days depending on size, while a traditional masonry extension
usually needs several weeks, especially with full finishes.
Can you build an extension on the roof?
Yes, provided we study the structural load of the slab, design proper rain-water drainage and apply correct
waterproofing and thermal insulation systems.
What is the difference between a traditional extension and a sandwich panel extension?
A traditional extension is heavier and has a classic massive look, while a sandwich panel extension is lighter,
much faster to build and usually offers better insulation. The choice depends on your budget, usage and structural
conditions.
Is buying sandwich panel from the “haraj” always safe?
Not always. Sometimes you can find good prices and acceptable quality, but you may also encounter damaged sheets or
unknown specifications. For permanent extensions and important projects, it is better to work with a specialised
contractor who guarantees both materials and installation.
