CONCRETE CMS Add-on for Real Estate Businesses

Making real estate website management easier and more robust.

The Concrete CMS add-on for real estate is a website management support add-on that allows you to manage all the necessary functions for a real estate site, from property management and property search to detailed page creation, 360° image display, and contact page navigation.

By simply registering property information, you can efficiently display it on list pages and detail pages, reflect it in search criteria, and even include images, floor plans, and 360° views.
Because property information changes daily, it allows for smooth updates, reducing the hassle of repeatedly requesting revisions from a website management company and enabling you to quickly disseminate information in-house.

From property management to page creation, this one tool handles it all.

You can manage information on various types of properties, including properties for sale, rental properties, and investment properties.
You can centrally manage all the information necessary for a real estate website, such as price, location, floor plan, area, nearest station, walking distance, year built, description, SEO description, images, floor plan, and 360° image URL.

The registered property information is linked to the property list, property details, and search form.
This eliminates the need to repeatedly enter the same information, significantly reducing the effort required for updates.


Use our advanced property search function to easily find the perfect property on our website.

You can search for properties using criteria that are easy for users to find, such as area, property type, price range, and floor plan.
By smoothly guiding visitors from their desired criteria to their target property, you can prevent them from leaving the site and create a pathway that easily leads to inquiries.

A real estate website that is "easy to view," "easy to search," and "easy to inquire about" is essential for running a website that attracts customers.


Supports 360° images and floor plans.

In addition to standard property images, we can also handle floor plans and 360° panoramic images.
This allows us to convey the atmosphere of the interior and the appeal of the property in a more concrete way, making it easier to provide information to customers before they visit our office or view the property.

360° images can be used to more realistically convey the sense of space and traffic flow, which are difficult to express through photographs alone.


Automated creation of property detail pages streamlines the update process.

By registering your properties, you can also create detailed pages for each property.
Creating individual pages with SEO in mind, in addition to list pages, makes it easier to attract search traffic based on location, property type, floor plan, price range, and other criteria.

Since there's no need to manually create each page, even real estate companies with a large number of properties can manage their websites efficiently.


Real estate website management with strong SEO capabilities.

You can set the property name, SEO title, SEO description, H1 heading, and body text description for each property.
Creating a page structure that is easily understood by search engines can also be used to improve search engine optimization by location and property criteria.

The key to increasing the traffic to a real estate website is not just creating a large number of property pages, but organizing them into meaningful pages with substantial content.


It can also be extended to integrate with Google Sheets.

In the future, we will be able to integrate with Google Sheets to handle the import, update, and write-back of property information.
By allowing sales representatives to manage property information using familiar spreadsheets and reflecting that information on the website, you can create an even more user-friendly real estate DX environment.

If it can perform updates based on property codes, check differences, create synchronization logs, and automatically generate pages, it can be used as a powerful business support tool for real estate companies.


This is a recommended real estate company for you.

This company outsources the updating of its property listings to a website development company every time.
A company that takes a long time to update its property listings and detail pages.
A company that wants to create an easy-to-use real estate website.

This is a practical website management system for real estate companies that goes beyond simply creating a website and considers everything from daily property updates and attracting customers to generating inquiries.

LINE integration and resource reservation management add-on

World's first Concrete CMS compatible LINE integration and resource reservation management add-on

This reservation system allows you to centrally manage everything from accepting reservations via LINE, checking reservation status, contacting customers, and managing staff and equipment, all from the Concrete CMS administration screen.

Concrete CMS compatible LINE integration and resource reservation management add-on

In typical reservation systems, the website, reservation management, customer management, and LINE communication are all separate, increasing the effort required for confirmation and data entry. This add-on allows you to directly integrate reservation functionality into websites created with Concrete CMS, enabling you to manage everything from reservation acceptance to post-reservation support in a single, streamlined process.

Customers can open the reservation screen from the official LINE account, check availability on their smartphones, and make a reservation. After the reservation is complete, a thank-you message will be automatically sent via LINE, including the reservation date and time and menu details.

The management screen displays the usage status of staff, rooms, beds, and facilities in a Gantt chart format. You can easily see who is responsible for which reservation, when, and which rooms and facilities are being used, all on a timeline.

For each booking menu, you can set the treatment time, consultation time, preparation time before and after, and the necessary staff and equipment. Even if a staff member is available, bookings will not be accepted if the room is in use or if there is a conflict with the bed or equipment, thus preventing double bookings.

We can accommodate not only regular closing days, but also temporary closures, changes in business hours, and changes in reception hours on specific days. We can display only the available times that reflect the actual business situation to our customers.

Customer support after booking can also be handled directly from the booking information. Booking confirmations, responses to requests, date/time changes, cancellations, closure notices, and emergency contacts such as typhoons and heavy snow can all be sent as individual LINE messages. The content of the message, the date and time of sending, and the sending result are saved as a history for each booking, so you can later check who you contacted and what message you sent.

The reservation list uses a collapsible display that is easy to view even when the number of reservations increases. You can open only the reservations you need to check the details, so the screen doesn't become too long even if there are more than 100 reservations registered.

We can handle a wide range of reservation services, including those for beauty salons, hair salons, chiropractic clinics, osteopathic clinics, acupuncture clinics, medical schools, consultation sessions, real estate viewing appointments, pre-funeral consultations, and reservations for meeting rooms and other facilities that require specific staff, facilities, or equipment.

Because it operates as an add-on for Concrete CMS, it can be integrated with existing functions and your own systems, such as website updates, inquiry management, customer management, and sales management. Instead of adapting your operations to an external reservation service, you can build a reservation system that suits your own operations.

Connect with us via LINE. Reservations and communication—all in one place.

By centralizing reservation acceptance, availability checks, resource management, and customer support, we achieve increased efficiency in reservation operations and improved service quality.
