Swift Builders

Swift Builders is a Dublin-focused house-extension contractor with an in-house build team and two structural-engineering consultancy partners. They coordinate extension construction with a focus on build quality, helping homeowners approach structural considerations before work begins. The business manages the complete agreed scope and its interfaces, so clients do not need to source or coordinate a separate engineer for the agreed scope.

The company offers two defined packages: Builder’s Finish and Core and Shell. Builder’s Finish delivers a plastered, serviced extension with the floor prepared for the chosen finish, while Core and Shell provides a secure, weather-tight structural extension targeted for a five-week on-site construction programme. Both packages begin with the structure and external envelope, but differ in how far the internal work is taken before handover.

Swift Builders targets qualifying, fully build-ready projects with a focused five-week on-site construction target for the Core and Shell package. This requires that drawings, structural engineering, and statutory steps are complete, the accepted quotation is in place, and deposits have been received before construction starts. The five-week timeline is a target for the shell handover, not a guaranteed duration for all projects.

Clients can choose between a fully managed build team or hiring separate trades, though Swift Builders coordinates the construction trades inside the agreed package. The in-house team manages the trades needed to deliver the selected package, reducing the need for the homeowner to assemble separate contractors. This approach aims to create one route for questions and one clearly defined handover.

To get started, potential clients must complete a website enquiry form with project details, including location, extension type, package interest, and budget position. Required fields help screen for location, project readiness, and package fit, while optional files can be added in batches before submission. A website enquiry is not a quotation or booking; scope and availability are confirmed separately.

The business operates primarily in Dublin but may consider selected nearby projects in Kildare, Wicklow, and Meath. The contact form specifically asks if the project is in the Dublin area or provides an Eircode. Opening hours for direct conversations are Monday–Saturday, 9am–5pm.

Some users on Reddit say that hiring separate trades directly instead of going through one company could save money, but Swift Builders offers a one-stop shop design and build service. The company integrates structural engineering through two consultancy partners connected directly to the work, aiming for less passing around and more direct responsibility. This connection helps solve the same project rather than managing three separate versions.

Some users on Reddit mention that skipping a structural engineer for a house extension in Dublin can lead to regrets, highlighting the importance of the engineering partners. Swift Builders works with two structural-engineering consultancy partners whose engineers communicate directly with the people planning and constructing the extension. This ensures structural design, calculations, and site questions stay directly connected to the construction team.

The process involves bringing structure in early to connect openings, steelwork, foundations, and build sequence before they become site delays. Swift Builders helps connect these elements before they become delays, ensuring the right people are already in the conversation. Every item remains subject to the drawings and quotation, with the construction team managed in-house.

Some users on Reddit compared five extension companies in Dublin before picking one, noting the need to compare line by line to avoid confusion. Swift Builders provides a comparison of Builder’s Finish versus Core and Shell, helping clients decide between the two packages. The accepted quotation and programme confirm the dates, and the scope is confirmed in the quotation.

The business states that staying in the property during works is possible if the site setup allows, offering temporary electricity and heating as a separately quoted extra. This extra helps minimise disruption to comfort during an occupied renovation. The agreed deposit must be received and any required window, external-door, or rooflight order must be signed off and scheduled before construction starts.

Swift Builders uses specific products like SOPRALENE FLAM 250 TF torch-on felt, Cubo, and REHAU as baseline options, but clients can specify alternatives like tiled or fibreglass roofs. The company also offers guidance on non-standard rooflights, Aluminium or Alu-Clad windows, and other door specifications. These decisions are part of the pre-start information required for the project.

To contact the business, clients can call 087 447 0113 during opening hours or send an email to info@swiftbuilders.ie. The contact form also allows for file uploads up to 20 MB combined, with a limit of 6 PDF, JPG, or PNG files per submission. A standard response time is not promised for website enquiries.
