What type of house extensions build Is right for you?

One of the most interesting and intriguing types of project – house extensions. The following ideas highlight a few common types of house extensions to choose from.

Single Storey Extension

Traditionally the most popular and incredibly cost-effective extension. A great way of gaining more space and allowing more natural light into the home, creating a brighter and healthier space.

Double Storey Extension

Create the most space in your home, giving twice the space of single storey extension but you’ll spend less per square metre. Get yours right, and it might make better financial sense than moving to a bigger house.

Garage Conversion

A great solution to creating extra living space in your Dublin home without losing garden space to an outside extension. You might want one to have a home office, gym, cinema or home improvement options.

Building design and construction process — step by step


Initial meeting and assessment

A site visit is deemed to be one of the most important steps in a construction project. Every house and every customer is different. Because of this, an initial reviewing of your house and discussing your vision face to face is the best way to get an understanding of your priorities and expectations.

The best result can only be achieved if we learn about what's special about your house extension and generally about your family. A personal conversation allows us to understand the full scope of work needed for your extension. And for you it can be an great opportunity to meet with the team who will be looking after the refit of your home.


Project price and detailed specifications

Investing your money into a construction project is definitely an important decision. Getting an accurate and transparent quotation is the first step to a successful house extension. Our job is to accurately assess the scope of work and come up with a project price, what's included and what isn't, and the nuances that are most cost-sensitive that might affect the final price.

At this stage we are detailing the specification: define the finishes and identify the suppliers for results that match your expectations.


Schedule of works and project commence

House extensions works could cause a disruption to your daily to daily life. Clear communication is as important as carrying out the work itself.

That is why making timely decisions: follow a clear process for requests, approvals, last minute changes and all decisions. We always try to keep our clients up to date and regularly report on progress and answer any questions during the process of the house extension.


Project completion

The final few days of the project tend to be the most difficult. You can't wait to finish the house extension project and move in to the new version of your home. There are always going to be some final details that need to be sorted. Finalising the last few nuances may seem tiring, after all the disruptions during work.

That's why we will always stand by you, for any final requests, questions and fixes. Seeing a happy and satisfied client is what motivates us every day.


Hand over documentation

Not only will we we see to a renovation project that is completed to its highest potential, but also we will make it our utmost priority to provide you with the complete set of documentation, certificates and warranties to accompany your ready made house extension.

What you should consider while planning a house extension in Dublin

Extending offers great potential for transforming your home, adding value and can be much needed in expanding families. Here are some tips you should know before starting your home extension project in Dublin.

Planning permission for House Extension in Dublin?

The answer to that question is likely “no”, as a house extension is considered permitted development. Broadly speaking, the construction of an extension does not require planning permission when it is to the rear of the house; however, any query from the public of this nature should be dealt with subject to the provisions of Schedule to the Planning and Development Regulations, 2001.

If the house has not been previously extended, the floor area of the proposed extension cannot exceed 40 sq meters. This exemption also allows for extensions above ground-floor level. Any above ground floor extension shall be a distance of not less than 2 metres from any party boundary.

What’s your budget?

It might sound like an obvious question, but a lot of people dive into a home extension project without a clear cut idea of what their budget stands at. This information plays a vital part towards the project scope that you can manage and will be a decisive factor when it comes to choosing realistic expectations of what can be achieved.

We are aware that our clients do not have an unlimited budget, which is why we will always be crystal clear about what you can expect with a given budget. Our house is our most valued asset and we totally get that, which is why at Timbermill Construction, we will always strive to squeeze as much potential as possible based on the budget, while maintaining a high level of professionalism and quality of work.

Make the best use of your available land

Will your home extension be the best use of your remaining land and there will be enough space left both in front and from the back? Are there any accessibility issues that need to be resolve before starting the renovation? We know that it may be hard to visualize what the final product will look like, but a simple markup of the site could prove to be very helpful.

House Extension Dublin: Frequently Asked Questions

Will a two storey extension be twice the price of a single storey one?

No, there is always a saving to be made in cost per square metre of the floor area gained with a two storey extension as the building is on the same foundations and has roughly the same size roof over it as a single storey extension but is a little more complex in its design.

How much does a home extension cost?

The price of a Dublin home extension varies massively depending on what your specification is and what exactly you want doing with your extension. Some people require a small bedroom and ensuite, other households need a brand-new kitchen or living space and some even require double storey extensions. The style of your extension will also affect the cost, depending on the type of windows and doors you would like fitted.

Do you guarantee your work? What is Your Warranty?

We are confident that our workmanship is of the highest standard and we provide our own free guarantee against our workmanship. We are well aware that our future success depends on satisfied customers and will always address any concerns after the project has been completed.
