Echostone Development

How We Build

scroll down
Slab, walls, and roof are constructed within 5 days. The EchoStone construction process is standardized to enable rapid and scalable construction. EchoStone employs a unique process that utilizes on-site concrete production in conjunction with state-of-the-art Formwork to enable a full placement of slab and walls in three days. Formwork is then removed from the walls for cleaning and a roof is installed; once Formwork is clean, it is immediately set up at the next site. Each house is finished with a standardized kit, improving the pace of construction while maintaining consistent quality.

There are four distinct steps in the process:

Site Plan & Prep

Multiple construction sites prepared simultaneously

The site planning and preparation process:

  • The EchoStone team performs sustainability assessment and develops plans to build with least environmental impact possible
  • Building sites are cleared and leveled
  • Reinforcement matting is laid into the slab Formwork
  • Concrete slab is poured, laser-leveled, and smoothed

Form Installation

Forms installed by hand – no heavy equipment required

Elements of Formwork installation:

  • Formwork is handset and weighs no more than 11kg, so no heavy lifting machines are required and job site safety is improved
  • Seven workers install complete formwork in two days
  • Electrical and plumbing prep work begins once forms are put in place

Monolithic Pour

Ensures an integrated, durable, and weather-tight envelope

CLC pouring process:

  • All pours are continuous and monolithic (not batch), and all houses are poured in a single day
  • Slab is poured in one hour, and walls are poured in two hours
  • CLC fully sets within a day, and Formwork is removed after 12 hours
  • Pipes for electrical and plumbing systems are embedded in the concrete for rapid finishing and installation of fixtures


Finishing work begins immediately after formwork removed

Elements of the finishing process:

  • All finishes designed for rapid and consistent installation
  • Roof is fitted in two days
  • Electrical and plumbing systems, doors, windows, flooring, and paint are standardized across houses
