Crafting a beautifully designed, livable home
Once the design of a house is finalized and construction begins, changes are typically not permitted. However, with our approach, you can select materials and colors while visiting the site, experiencing the space firsthand, and visualizing the final outcome.
The defining feature of our home-building process is the ability to collaborate with our designers right up until the last minute. This flexibility brings a dynamic, "live" feel to the creation of your home.

We can secure a competitive construction quote from the contractor
As an architectural design firm, Robecity offers you the flexibility to choose from our affiliated contractors for your property's construction. We can provide competitive quotes from several of these trusted partners. Rest assured, Robecity does not take any margins from our partner contractors, ensuring that your budget is fully invested in creating the best possible design. Alternatively, you are welcome to work with a contractor of your choice.

A warranty comparable to that offered by major home builders
In compliance with national standards, we provide warranties for our properties equivalent to those offered by major homebuilders. Features such as insulation, earthquake resistance, functionality, and low-maintenance living come standard.
Additionally, Robecity homes stand out with their unique, original designs that are both stylish and one-of-a-kind, adding exceptional value beyond the basics.

Customized and flexible delivery schedules
Although our architecture is entirely custom-made and unlike any other, our turnaround time remains standard. We carefully manage the schedule to ensure there are no delays caused by our commitment to design excellence.
However, if a client wishes to focus extensively on design details, we will collaborate closely to perfect the project without being bound by strict deadlines, ensuring complete satisfaction.
