Give your living plans space with an extension
Do you want more space in your home, but do you actually live exactly where you want to live? With an home extension, you enlarge an existing space and make better use of your home. Think of a longer living room, a more spacious kitchen, or one large living space with more connection to the garden.
Van Der Hart Timmerwerk handles your home extension from the initial preparation to the construction and finishing. We coordinate the structural and carpentry work, keep the lines of communication short, and ensure you have a single, dedicated contact person throughout the entire project.
- Custom home extension for your property
- Construction and carpentry within a single project
- A single point of contact during the renovation
- Clear agreements regarding planning and execution
Extending your home and experiencing the space differently
A few extra meters can make a big difference in how you live day-to-day. Perhaps the living room is currently just too small for a large dining table, there is no room for a kitchen island, or you want to connect indoor and outdoor spaces more strongly. By extending your house, you don't have to go searching for another home to get more living space.
A good addition is not just about extra square meters. The new space must connect logically to the existing layout, receive sufficient natural light, and feel as if it has always been part of the house.
That is why from the very beginning we look at the big picture. We discuss your housing wishes, examine the existing home, and translate that into an addition that is structurally sound and works well in daily use.
How you can extend your home
Every home and living wish is different. That is why we do not build from a standard solution, but look at the space you want to create and how it best fits your home.
Extend living room
An addition to the living room creates more space for a spacious sitting area, a dining table, or a different layout of the living space. Because the rear facade is moved, you can rearrange the existing living room and use it much more efficiently.
Extend the kitchen
Do you dream of a larger kitchen with a kitchen island, extra cupboard space, or a long dining table? Expanding the kitchen creates the space to better connect cooking, eating, and living. In doing so, we take into account walking routes, daylight, and the connection to the existing living room.
Rear extension
The rear of a home often offers good opportunities to create extra living space. You extend the existing ground floor toward the garden and can simultaneously ensure more light and an open connection with the outdoors using large windows or doors.
Side extension
For a corner house, semi-detached house, or detached house, the side can also offer possibilities. This allows you to, for example, widen the kitchen or add extra floor space to the living room. We will examine on-site how much space is available and which construction suits the house.
More light in your new living space
Extending a home immediately offers the opportunity to bring in more natural light. Think of wide facades, French doors, large window frames, or a skylight in the roof. We look at the orientation of your home and together we choose a solution that fits the desired appearance and amount of light.
An extension that forms a seamless whole with your home
Every home and housing wish is different. That is why we do not build an extension based on a standard solution. We look at the space you want to enlarge, the existing architecture, and how the new square meters can best contribute to your way of living.
We will discuss topics such as the dimensions, position of windows and doors, roof shape, facade finishing, and the desired connection to the garden. The extension can blend in with the original house as much as possible, or you can opt for a modern addition with plenty of glass or a different facade finish.
Especially in the connections and finishing, there is a lot of custom work. Because we also carpentry within the project can be executed, construction, finishing and details fit together neatly.
Extension or add-on: what fits your plans?
An extension and an add-on are often used as the same terms, but there is a practical difference in the way both solutions are usually meant.
With an extension, you enlarge a space that is already part of the home. For example, the living room or kitchen extends a few meters further and, after the renovation, forms one larger living space.
An extension usually adds a new space to the house, such as a utility room, study, or other separate room. Do you want to add such a new space to your home? Then check out our options for a house extension.
Are you unsure which solution fits your situation? During an on-site visit, we can look at how best to utilize the available space.

We zijn erg blij met ons project – 'Een berging met een naastgelegen Overkapping'. Ik kan alleen de positieve punten opnoemen. Joey is erg punctueel, netjes, transparant en zeker professioneel in zijn taak en tevens een harde werker. Joey reageert snel en is ook een meedenker (wat erg fijn is) en ons tot veel meer creativiteit en slimme (technische) oplossingen heeft gebracht. In het kort – topvakman ! Dit zal zeker voor ons niet het laatste project zijn. Zeker een aanrader!Geplaatst op Google![]()

One construction company for your complete extension
Having an extension built requires various tasks that must connect with each other at the right time. From the foundation and load-bearing structure to window frames, insulation, and the final finishing: every step influences the end result.
Van Der Hart Timmerwerk can take care of the construction and carpentry work within the complete project and coordinate the execution for you. Depending on your home and plans, the following work can be part of the extension, among others:
- Preparatory and construction work
- Demolition work and creating the opening
- Earthwork and foundation
- Structural framework and construction
- Roofing and cladding
- Installation of window frames, windows and doors
- Insulating the new construction
- Connect to the existing house
- Carpentry and custom work
- Finishing of the new living space
Would you like to combine the extension with modifications to other rooms? Then we can look into whether the work can become part of a complete renovation of your house. That way you don't have to manage a different party for every component.

What does a home extension cost?
What an extension costs depends heavily on the home, the dimensions, and the choices you make. A compact extension with a simple finish requires a different investment than a wide kitchen-diner with large glass panels, custom work, and a high-end interior finish.
The existing situation also counts. Think of the required foundation, the size of the opening in the existing facade, and any adjustments to the load-bearing structure. As a result, a general price per square meter is not always a good predictor of what your extension will actually cost.
Therefore, we first inspect the home and discuss what you want to achieve. Based on that, we map out the work and can provide a suitable quote for your extension.
WhichWhich choices affect the costs?
The final investment is determined, among other things, by:
- The width and depth of the extension
- The required foundation
- The supporting structure and the size of the opening
- The type of roof construction
- The number and size of window frames
- The amount of glass
- The chosen facade finish
- Insulation and material choices
- Carpentry and custom work
- The desired level of interior finishing
Do you need a permit for an extension?
Whether you need an environmental permit for an extension depends on the construction plan and the rules that apply at your location. The position of the extension, the dimensions, and the existing home can play a role in this, among other things.
Even when you are allowed to build without a permit, building regulations still apply. For example, the extension must comply with the technical regulations that apply to structures. Depending on the design, architectural drawings and structural calculations may also be required.
Via the Permit check of the Environment and Planning Portal can you check whether you need a permit for your plans, have to submit a notification, or need to provide information. During the preparation, we will discuss which steps apply to your extension.

From initial idea to a completely finished extension
Expanding your home starts with a clear picture of what you want to change and what is structurally possible. Therefore, we first look at your wishes and the existing situation before determining the execution. Afterward, we make clear agreements about the work, schedule, and next steps. Throughout the entire process, you will have a single fixed point of contact.
Step 1 – Application and introduction
You let us know what you have in mind, big or small. We will contact you to discuss your wishes, ideas, and expectations.
Step 2 – Site Visit
We will visit you to inspect the home and the available space. This gives us a clear picture of the current situation and allows us to provide targeted advice on the possibilities.
Step 3 – Proposal and non-binding quote
Based on your wishes and the situation, we will create a clear proposal. You will receive a non-binding quotation in which the discussed work is clearly described.
Step 4 – Design and preparation
Following approval, we will elaborate the plans further. We will coordinate the construction, materials, schedule, and necessary preparations with you, ensuring everything is clear before we start.
Step 5 – Construction and finishing
Our team realizes the expansion and ensures that the various activities are well-coordinated. During execution, we will keep you informed of the progress.
Step 6 – Delivery
Upon completion, we will review the work together. We will check the execution, discuss any points of attention, and ensure a neat delivery of the new space.
Why extend your home with Van Der Hart?
An extension temporarily has a major impact on your home. Construction takes place against the existing house, an opening to the inside is created, and multiple tasks follow one another in quick succession. At that point, you mainly want clarity on who is responsible for what and to ensure that agreements are kept.
Van Der Hart Timmerwerk combines construction work with craftsmanship in carpentry and custom work. As a result, we can coordinate many parts within a single project and keep communication channels short during the renovation.
We discuss important choices in advance, maintain an overview during execution, and ensure you have a single dedicated contact person throughout the entire project. The goal is not just more square footage, but a living space that suits your home and that you will enjoy for years to come.
This is why customers choose Van Der Hart Timmerwerk:
- Craftsmanship in construction and carpentry
- Custom-made tailored to your home
- Various activities within a single project
- Clear agreements regarding planning and execution
- Direct communication during the renovation
- Single point of contact from application to delivery
Frequently asked questions about extending a home
How many meters can you extend a house?
How long does it take to build an extension?
The construction time depends on the size, construction, and desired finish of the extension. Preparatory work also affects the total lead time. Before starting, we will clearly discuss the schedule and main construction phases with you.
Can you continue living in the house during the extension work?
In many situations that is possible, but there will be nuisance during certain phases. Especially while creating the opening between the existing house and the extension, you will notice the work more. We will discuss in advance what you can expect per construction phase.
Can you completely finish the extension?
In addition to the structural and architectural work, we can take care of various finishing components. Exactly which work we include is clearly established in advance in the proposal and the quotation.
Can every home be extended?
Not every home offers the same possibilities. The available space, existing construction, foundation, and location regulations all play a role. During a site visit, we can assess what is technically and practically feasible for your home.
More plans for your home?
Perhaps you would like to tackle other parts of your home in addition to expanding it. Van Der Hart Timmerwerk can coordinate various construction and carpentry work within a single project.
