Tatami: modular house with a great touch of digitization

The current situation, where builders and authorities are striving for fast construction, requires disruptive solutions. Because it is in traditional construction and development that a number of years pass between the first idea and the final delivery. With this, you will never-never-not be able to build the desired approximately 900,000 homes before 2030. So how? According to Pepijn van de Weijer and Kasper Hesp, ‘their’ Tatami offers the solution: modular with a good touch of digitization. Real estate news in conversation with two visionary developers.

Pepijn van de Weijer is co-founder of Tatami with his New Cheese Development partner Jeroen Koops and with Stan Vermeulen. Together with Kasper Hesp, he is part of the team that can address all aspects from the first idea to the final realization of the homes. Pepijn van de Weijer: “We started Tatami from a construction perspective with product development as a reference: what could be done better and more efficiently? As we did so, we also began to think about improvements in the development process. Especially to get a good idea of ​​the feasibility of a business case as soon as possible. ”

In the current reality, it is becoming increasingly difficult to meet the growing legislation and rules and the package of requirements that the municipalities have when it comes to the interpretation of especially the city center buildings and transformations. Projects that often require the pressing of dozens of buttons at the same time to arrive at a feasible business case. Pepijn van de Weijer: “Because we use fixed modules and our collaboration with OMRT., We have [zie hiervoor: digitalisering essentieel, red.], very fast clarity on costs, revenue and feasibility. As a result, we arrive at the most optimal volume for a particular location. With a good picture of costs and revenues. In this way, we arrive at a result much faster. Much faster than traditional, where you not only spend much longer time on surveys and sketch designs that have to be recalculated after each change. But it is also very difficult to leave a chosen path if it turns out that one can not come up with a feasible business case. We already have clarity about the program, the costs, the benefits and the procedure in the start-up phase. We can achieve that in a very short time. ” To which Kasper Hesp adds: “The collaboration with OMRT gives us digital tools to accelerate and clarify the decision-making process around area development and housing construction. The design and development process becomes more objective and transparent, creating more room for quality and the human side of the process. Because we are based on modular elements and are dependent on OMRT’s smart software, we can go through a development process much faster with a municipality, and the path to an environmental approval is greatly shortened. ”

Sure, speed
In this time of rapidly rising material costs, Tatami’s modular approach offers another advantage over the traditional approach. Pepijn van de Weijer: “Before we enter the construction phase, in fact the assembly phase, we know exactly how much material will be used for the modules. It is, of course, very comfortable in these times when building materials almost have a daily price. In addition, it ensures that with our modular approach you have almost no (residual) waste and error costs. You can buy much tighter. Because as a developer and builder you know more precisely where you stand in terms of price, I also expect you to reach an agreement much faster. ” Kasper Hesp: “In addition, you go in the traditional design and development process from sketch design, to pre-engineering, final design, technical design, implementation design, and you go more and more in depth. In our case, these phases are very shortened or even partially skipped. The details are already known at the beginning of the process. This means that the builder knows what to do early in the design and construction process. It ensures on the one hand acceleration, on the other hand it ensures that you have a sharp insight into the cost price. We can also not escape the sharply rising construction costs, but we can do much better. It is also an advantage of the modular approach. Traditionally, a price is set in the DO phase, where the contractor still has to make a technical design. Because prices fluctuate so much, it creates huge risks. Moreover, the post with our approach can be unforeseen reduced enormously because we largely know what to build. For the developer, there is less room for construction errors, and the error costs are limited. ”

Development profit versus total cost of ownership
Tatami’s involvement does not end with the completion of a project. In fact, Tatami will also remain involved in the exploitation phase. Kasper Hesp: “Based on this commitment, we monitor the building’s performance in areas such as air quality, light incidence, energy and water consumption. By measuring and analyzing performance, we can improve it. By monitoring performance, it can be ensured that a Tatami home is optimized. We learn in the management phase and can then apply that knowledge again. ” To which Pepijn van de Weijer adds: “The Tatami business model is therefore completely different from a traditional developer who wants to go for profit maximization while looking at the total cost of ownership. Together with our partners, we strive for a good balance between the necessary development profit and the return we provide in the subsequent utilization phase. In addition to developers, we as an operator have been involved for a long time, and emphasis is placed on delivering quality that ultimately pays for itself in the utilization phase. In the traditional model, there is hardly any incentive for the developer to deliver more quality than necessary. Although it is of added value to the investor who buys the project. ”

Tatami is currently in dialogue with various municipalities and is also working on the realization of a number of projects. In addition, it is actively looking for parties that have land positions and want to transform them into a sustainable investment with beautiful, sustainable and affordable housing. Pepijn van de Weijer: “We would like to get in touch with parties who are interested in the possibilities in their position and would like to do a feasibility study for them. Not only do we look at different scenarios for the design, development and realization of the plan, but we can also provide the necessary funding if desired. ”
