Expansion architect The Hague

When people want more space to live or work, they often think of moving. However, this is not always necessary, because the current building can also be expanded. Not sure where to start when you want to expand your home or property? Please contact the architects at CNCPT A, we will be happy to help you with a suitable solution. View our extension projects below or view the other ways to expand your home.

Our cities, here in the Netherlands even more than anywhere else, are becoming more populated every day. The number of square meters of plot per inhabitant is decreasing by the minute. The price of real estate is skyrocketing. New visions to solve the problem in the future are emerging and discussed on architectural, social and political platforms. Old and new ideas about public ownership and concept sharing are examined and analyzed on various aspects of modern life.


But, what should you do if right now your current house just doesn’t fit your lifestyle anymore and you can’t afford to simply swap it for a bigger one or wait for future solutions? We suggest to have a look at your property with the same sustainable approach we would advise for any of your beloved belongings and analyse if you can reuse, repair or recycle it. In terms of a house this means remodelling it to your current needs, fixing the broken parts and closing the energy leaks and finally, being conscious of the lifecycle of all the materials you make use of and dispose.


The majority of our clients come to us with this exact dilemma. Of course, each house and owner are different and they all need a slightly different solution, but there are many aspects that they do have in common. Often the solution is a new, bespoke layout and a relatively small extension to the house. And, as the majority of the properties are terraced houses, you can extend only in four ways: to the back, up, down or internally.


The steps of designing an extension project

At CNCPT A, we divide the process of expanding a building or house into 9 different steps. Below we explain exactly what these steps entail.

Step 1: initiation

The first step is to map out the current situation, we call this the initiation. During this step we find out what is possible within the existing zoning plan of the house or building. During this step we also make a concept sketch design based on your wishes and ideas. Read more about the initiation phase.

Step 2: preliminary design

The second step is all about making a preliminary design. This means that we map out the design of the extension. To give a clear picture, we use 3D visualisations. Read more about the preliminary design phase.

Step 3: final design

During step 3 we focus on the materialization and you have the option to have an element budget drawn up. An element budget provides insight into the approximate cost of the extension. If desired, you can still adapt the design to your budget. Read more about the final design phase.

Step 4: environmental permit

If an environmental permit is required, we will start working on it in step 4. Read more about the environmental permit phase.

Step 5: technical design

Step 5 is all about making a technical design. At this point in the process, the final design has been completed and the permit has been requested from the municipality. We also record the construction preparations and necessary data during this step. Read more about the technical design phase.

Step 6: tender

In step 6 it is time to tender. You have the option to request a quote from various contractors. By putting out several quotes, you can compare the prices with each other. Read more about the tender phase.

Step 7: contract formation

Step 7 is all about drawing up the contract, also known as the contracting agreement. This describes what has to be made, what the costs are, the guarantees and the starting moment. Read more about the contract formation phase.

Step 8: Execution Design

During step 8 we will work on coordinating the implementation technology, materialization and detailing. Read more about the execution design phase.

Step 9: Build

Step 9 is the most fun and also the last step, namely the actual building. During this period the extension is being built and you can see little by little that the design really comes to life. Read more about the construction phase.
