The Construction Process – Less work than you might think

Whether you’re doing a DIY build or having a professional team do it for you, the construction process is a vital part of your new home. In this article we’ll explore the construction process of a modular Ieshahomes house from start to finish. (Please note that this excludes our pre-assembled homes.)


1. Putting in the footings

The first step to the construction of your home is marking out the  location of the footings. This normally done using spray paint. Holes are then dug at these locations using an auger. The depth and locations of these holes will depend on how reactive the soil is as well as how tall the poles will be.

Concrete will then be poured into these holes, the poles will be set in this concrete and the rest of the hole will be backfilled with dirt around the poles.

2. Erecting the house frame and sub-floor

Secondly, structural steel frames are delivered to the site as a large set of pre-cut and drilled elements ready to be screwed together. Now that the footings are in, these steel frames will form the sub-floor, wall frames (including windows and doors), and roof frame. This part of the construction process will already see your Ieshahomes house taking shape.

If you have chosen to have a deck, the sub-floor will be extended according to the floor plan. The frames for stairs or steps will also be erected. Depending on the height of the poles, the first one or two stairs/steps are set with concrete, then the steel deck frame and step plates are installed. To complete the sub-floor, concrete will also be set on top of the steel frame, providing a base for your SIP flooring system.

After this, the frame must be braced. Bracing involves cross-braces added between the frame to help make it stronger. These cross-braces are added diagonally and are made of steel.

3. Installing the SIP roof system

The SIP roofing system by Delta Panels is considerably less complicated than installing tile or metal roofing, and typically won’t take more than a day to put on. This heavily reduces the amount of time needed to be spent in this stage of construction, quickening the build time overall.

Because the SIP system is all-in-one, the panels are delivered pre-formed with a smooth ceiling finish on one side, and a durable corrugated sheet on the other. Insulation is also taken care of, sandwiched between these sides as a foam core.

After guttering is installed, the panels can be safely affixed to the roof frame.

4. Installing the exterior SIP walls

SIP walls are delivered to the site with all other SIP components and are simply installed to the frame of your Ieshahomes house. The SIP panels and are comprised of two steel sheets with an insulating foam core in the middle. Our suppliers complete the construction of all SIP panels before they’re delivered to you. This means that they are pre-formed and don’t need any additional layers of support or insulation.

Now that the walls are installed, elements such as windows and sliding doors can be fitted into place.

5. Roughing in plumbing and electrical services

The electrical services that need to be roughed in will depend on what’s planned for the house, but generally include:

  • Lighting
  • General purpose outlets or GPOs (i.e. power points)
  • Ovens and cooktops
  • Rangehoods
  • Air conditioners
  • Heaters
  • Fans
  • Electric hot water units
  • Smart Wiring / structured cabling
  • Home automation systems
  • Etc.

6. Installing the interior SIP walls and floor

The same process used for the exterior walls is applied when installing the interior walls. Interior doors are also added at this point.

The floor panels work in with the same SIP system Ieshahomes uses for the roof and walls. Your INEX or JH floor panels are securely affixed to the concrete sub-floor and wall frames. Floor panels are installed inside the house and come standard with decking, however some clients may choose an optional timber fascia instead of the floor panel system.

7. Tiling and waterproofing

Waterproofing is generally needed anywhere where there’s a water outlet. This includes:

  • shower stalls
  • bath areas
  • bathrooms in general (depending on other materials used)
  • laundries
  • wet areas in kitchens
  • around all penetrations in areas to be waterproofed (e.g. taps, drains)

8. Fitting the interior and deck

At this stage all interior elements can be added. This includes the kitchen cabinetry, counter tops, sinks, built-in appliances, and toilets. Plastering work is also done at this stage.

If you’ve chosen to have a deck, it can now be fitted with the appropriate railings and aluminum slats. An optional timber fascia can be installed over the steel stairs/steps that have already been put in place.

9. Connecting the fixtures and fittings

Once all interior elements are added, they can then be fit to the plumbing and electrical services. After this stage the house may be complete and ready for inspection.

10. Putting up the exterior wall cladding (optional)

If required, wall cladding is installed over the external SIP wall panels. Ieshahomes offers two panel options, one which has the external cladding built in (DELTACOOL by Delta Panels), and the other which can be customised with cladding. If you chose the latter, your BONDOR walls can now have their MATRIX cladding put up.

– Inspection Ready –

After the construction of your home has been completed, it will have to go through a mandatory inspection. It’s very important – for the sake of safety and compliance – that your home is properly inspected by a qualified surveyor at various stages of its construction to ensure that it meets the relevant standards, local regulations and Building Code (BCA) requirements.

Once the house is complete, there’s still the matter of making sure everything’s exactly as it should be, and settling on final payments. The final inspection can be done by the home owner or a hired professional (on behalf of the home owner). The final handover of a new home involves inspecting the work that’s been done on the grounds of workmanship, and on whether what’s been delivered is what’s specified in the contract.
