How long does it take to build a two-storey extension in Ireland? Here's the scoop!

What is Double Storey Extension?

A double-storey extension is a great way to add extra living space or bedrooms to your property. Without the hassle and expense of moving house, you can build up two new floors at the rear or side of the building – as long as you get planning permission. Here's a 5-Step Guide for building one:

  1. Decide what the extension is for – living space, bedrooms, or something else.
  2. Choose an architect and builder to help you design and plan it.
  3. Budget for the project – extensions can be costly.
  4. Get planning permission before any work begins.
  5. Start construction – dig foundations, build, and follow safety regulations.

When building a double-storey extension in Ireland, many factors must be considered. Structural integrity, insulation, and fire safety all need to be taken into account. Choosing an experienced contractor with prior experience in similar extensions is best.

Remember to keep your neighbours' privacy in mind when doing any type of extension. Stay on good terms with them by involving them in important decisions.

Double-Storey Extension Vs. Single Storey

Planning permission:

  • Double-storey – Will need.
  • Single-storey – May not need.

Build time:

  • Double-storey – Up to 6 months.
  • Single-storey – Up to 3 months.

Cost:

  • Double-storey – more expensive.
  • Single-storey – Less expensive.

Additional space:

  • Double-storey – More.
  • Single-storey – Limited.

Note: Build time and cost depend on size, design, materials, and location.

How Long Does a Double-Storey Extension Take to be Built?

Time for a two-storey extension can vary. It can take 6-12 months. Start with site prep and planning, which takes weeks. Then, foundation, framing and roof installation. Followed by interior and exterior finishing, including plumbing and insulation.

Local regulations need to be considered. In some cases, it's done in less than six months. However, delays may extend beyond 12 months.

How Much Does a Double-Storey Extension Cost?

Constructing a double-storey extension can be a huge investment for homeowners. It offers more room, natural light, and a higher value for the property. But what is the cost? Below is a table with cost factors and price range:

Price Range:

  • Planning Permission: €800-€1,200
  • Building Regulations Approval: €600-€900
  • Architectural Design Fees: €4,000-€6,500
  • Structural Engineers Fees: €2,000-€3,500
  • Groundworks (foundation & excavation): €9,000-€14,000
  • Brickwork/Walls: €12,000-€20,500
  • Roofing/Skylights: €8,000-€12,500

Electrical Work/Plumbing/Central Heating/Radiators: €15,500-€25,000

It's important to know that these prices are just estimates and may differ depending on the project's location and specifications. The size of the extension and materials used can also influence the cost.

An efficient way to save money is to prepare ahead and get accurate quotes from multiple contractors before beginning construction. Don't forget to include furniture and décor in the budget too!

What Fees Can I Expect to Pay?

When planning a two-storey extension, it is important to consider the fees. These can vary depending on size, location, design and materials. Here are some expenses to expect in Ireland:

  • Permission fees
  • Architect and engineer fees
  • Surveyors and structural engineering fees
  • Building materials and costs
  • Connection fees and taxes

Additional costs could arise due to groundworks or existing structures. Get accurate quotes from contractors before starting. This way, you can budget and avoid surprises.

Planning fees

Getting planning permission costs are a must-think when starting a two-story extension project. Ireland's fees for planning applications can change depending on details like locale, size and kind of development.

Also, note that extra costs might be added for changes or re-submissions. To stop any hold-ups, consult a professional architect or planning advisor who can give information on related fees and needs.

How to Cut the Cost of a Two-storey Extension

Want to save money on a two-storey extension in Ireland? Here are some tips:

  1. Keep the design simple, and don't add custom features.
  2. Check if your local council offers grants or allowances.
  3. Do some of the jobs yourself, e.g. painting, decoration, and fixtures.
  4. Shop around and get quotes from multiple contractors.

Also, some homeowners spend too much on extensions without approvals. This can cause delays and extra expenses, so ensure you comply with regulations and laws.

Planning a double-storey extension

Expanding your Irish property with two levels can be daunting. To begin, ponder the variables that affect the duration of the job. Here's a 3-step guide for planning a double-storey extension:

  1. Consult an architect and a structural engineer to design the plan.
  2. Apply for planning permission from your local council. This could take 8 weeks or more.
  3. Hire a reliable contractor who has experience in this field. Construction can take from 4 months to over a year.

Keep in mind that permission time may be less than 8 weeks, and building time depends on the scale of the work. To save costs and quicken construction, reserve materials early.

Designing a double-storey extension

Expanding your home with a two-storey addition is a big decision. Planning and designing it can be complicated. To help you, here is a table of the key stages in the process.

Stage       Description

1  Consult with an architect or designer

2  Measure and survey the space

3  Make concept drawings

4  Finalise designs and make detailed plans

5  Get planning permission (if needed)

The length of each stage depends on your needs and the project's complexity. For example, if you need planning permission, this could add months to the timeline. Once your plans are final, construction can start. This includes getting building permits, picking a contractor, and doing the building work.

Designing a double-storey extension needs a lot of time and money. But, the right planning can improve your home's look and value.

Also, designing a two-storey extension is more complex than a single-storey one. This is because an architect or designer must ensure it is structurally sound on both levels.

Maximising the impact of the indoor-outdoor link

Interconnection between indoors and outdoors is a must for modern living. Enhancing this connection can elevate your home's ambience and create a more enjoyable space. Incorporating elements to blend the interior with the exterior helps maximise the relationship between both.

One way to maximise the balance between indoor-outdoor flow is by using large windows, doors and skylights, enabling natural light to enter your home. Consider adding an outdoor covered area that will allow you to expand but remain connected to nature. A filtered or open garden room can integrate well with the fauna and greenery.

Furniture placement is also key in achieving optimum indoor-outdoor flow. Place furnishings close to windows, doorways or outdoor zones set aside for such use. Furnishings should reflect nature – soft curves, earthy tones and clean lines bring out the beauty of the environment and blend well with the surroundings.

Incorporating these indoor-outdoor features into your home will create a harmonious relationship that enhances functionality and style.

How to clone into other project?

  • Press "Ctrl + E" or "Cmd + E" in the Designer and enable "Select on-page element".

  • Search for the class named, "Cloneable Area".

  • Copy the element inside this container to your own project.

  • Rename the classes accordingly if they are clashing with your project.

  • Ensure custom code from the in-page setting has been copied into your project as well (if there's any).

  • 'Page Trigger' interaction can't be copied directly. You can only clone the whole project, or rebuild it.
    A simple trick to copy the 'Page Trigger' interaction into another project is as below:

    1. Create a dummy element.
    2. Apply any type of 'Element trigger' into the dummy element and select the 'Page Trigger' animation.
    3. Copy the dummy element with the animations applied into your new project.
    4. The animation should have been copied into your project and you can reapply the 'Page Trigger' animation into your project.

  • If you have further inquiry or need assistance, feel free to contact us.

  • Lastly, please do not copy this project and claim it as your own. We wish to continue sharing and giving to the community. In order to do so, we will need your cooperation and full support. Thank you very much,
