Loft Conversion- 9 May 2026
From start to finish, Pov and his dad were outstanding. They communicated clearly throughout, were professional and genuinely pleasant to work with and they completed the job to a very high standard. I wouldn't hesitate to use ARPO Building Services Ltd again for future projects and I would highly recommend them to anyone looking for reliable, high-quality builders. You won't be disappointed.

Extension Builder in Derby
Hi, Im Bret, BBL’s owner! I’ve been in the landscaping business for over 15 years working on site mainly until BBL was started in 2020. Whether it’s a new driveway you need, a fresh patio, fencing or drainage we’ve got you covered in all areas. We’ve also started taking on all other building work such as extensions, conversions, new kitchens/bathrooms and any joinery needs, with my partner Nick taking over that side of things who has over 35 years experience in this field. We are perfectionists and want to bring our customers visions to life. We only use the best quality materials and cut no corners!

Carpentry- 19 Jan 2019
Some good points, some bad. Jobs crossed over which meant mine was delayed and he kept disappearing to sort problems with another job. This made me late starting to trade from that building. Only put ceiling on the office and none of the other rooms leaving all cabling/electrics bare. Added extra on at the end of the job for electrics. Used ready fixed concrete plinths(?) to run ceilings from which meant the walls were too high. This made the 2nd tier useless due to there being only just over 5' before you hit your head on the ceiling. Very expensive when taking the value of the materials and time taken into consideration. Nice guy but would not use him again. My advice... get everything drawn up and in writing! This is my second time using mybuilder and my last. It is full of cowboys and when reported, mybuilder do NOTHING about it!!

Extensions- 17 Nov 2023
Hired Rob to build a large 2 storey wrap around to a 3 bed detached house and a full new roof over the whole thing. Rob worked directly on the project along with Paul and together make a great team. From the offset Rob was confident in how he would approach each element of the job and was proactive in planning ahead and ensuring he had plant and materials on site when needed. Rob called in other trades when required such as plumbing, electrical and a firm to pump and lay concrete flooring. He involved me as much as needed when decisions were to be made throughout the job but was always busy and kept a high pace of progress all the way through. Communication with Rob was good throughout the project both with regards to finances and timescales. This was key so we could tackle and overcome unforseen circumstances together. Ultimately Rob, and Paul, have left me with an amazing house I love coming home to.

What to ask a Derby extension builder before hiring?

Before hiring an extension builder in Derby or extension building company in Derby, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Derby 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 Derby 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 Derby?

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 Derby 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 Derby 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.
