Cole and Gary are incredible, along with being incredible tradesman, great communication, quick quote to completion of job and completely professional, funny and generally lovely people, they managed to rebuild a very sentimental stone BBQ which had been brought down during my recent garden renovation... its not only rebuilt but restored to its natural stone and it looks incredible. Just to add the heavy rain didnt even deter them they grafted under a Canopy to make sure my BBQ was rebuilt in time for a family party.... Legends... cant thank you both enough!!

Conversions - General- 23 Aug 2021
We converted our garage into a Garden Room and side shed and employed Oakspan for the job and are delighted with the outcome. Kevin and his team turned up promptly each day and as a result of their impressive work ethic the job was completed in a short space of time. They always left the site tidy at the end of each day and Kevin was good at providing suggestions/ideas of what we could do. I would certainly employ Oakspan again for future work and would thoroughly recommend them.

What qualifications and experience do you have as an extension builder in West Lothian?

An extension builder in West Lothian should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your West Lothian extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in West Lothian?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the West Lothian extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most West Lothian extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
