Client Testimonials


Example abc1

Ray & Marianne Jones, Independent Hearing Services

What a fantastic job you have done! Well done to you and Building Additions. Everything was done as you promised and on time too! Moreover, the price you quoted was most reasonable and very fair, We have no hesitation in recommending you and your marvellous team. Thank you so much.

Mr. & Mrs. Rea, Christchurch

I want to thank you for the superb garage conversion you did, It has now been well tested by the family and to quote one grandchild “that is better than the Hilton” Truly it is all we could possibly have dreamed of having . Your support team were all so very willing and all had the ‘can do’ attitude. It was a pleasure to have them. A good job, well planned and executed, Thank you.

Mr. & Mrs. Doe, Upton Poole

The quality of work carried out was excellent. Mr. Bamber consulted with us at every point from the beginning discussions to the finished work, making sure we were happy at every turn and also assisting us in making decisions and giving us ideas that worked excellently. We would have no hesitation recommending Building Additions; keen price, excellent standard of work, attention to detail & producing a high standard of work, courteous, professional and extremely helpful and always clean and tidy. Thank you so much for a great job done.

Rachel. S.

We’ve used building additions on several occasions now and always found them to be very professional.the work has always been completed on time and to a high specification.

They’re prices are very competitive too,and john was friendly and approachable when we needed to discuss changes at the last minute.

Mr. & Mrs. Winfield , Poole

A really efficient and honest company to use. They did a really great job and stuck to time scales and the quoted price.

I would definitely recommend them.

Mr. & Mrs. Buttimore

Hired for ground floor extension to provide living / bedroom area and shower wet room. Overall I can say we are extremely pleased with the end result, in fact it has turned out to be more impressive than we imagined. Positives include quality of work, helpfulness of trades people throughout and tidiness which was also remarked on by our neighbours. The only area I could criticise is that the job did take longer than first given, however we did make some changes, so this is understandable.

Mr. Small

Wouldn’t hesitate to recommend John and his team. They completed the job professionally and on time for what I thought was a very competitive price.

I have since hired John again for other work.

Mr. French, Upton, Poole

I must praise the guys in their working practices, quality of work and behaviour on site…the clean-up left very little sign they had been there, to the point I was going to show someone the membrane and I thought there would be some off cut lying around but could not find any! Also, a neighbour…kept informing me how well the guys got on with the work, no swearing, neat and tidy very organised and fast working. Thank you once again for getting the job done quickly and of such high quality.

Mr. & Mrs. Blandford, Fordingbridge

My wife and I obtained a number of quotes from building companies, and we found Building Additions to be the most competitive. We were extremely happy with the building work to convert our garage into a bedroom with en-suite, playroom/living room and utility room. John was always very courteous, professional and personable. We have since used Building Additions for other work and intend to do so again in the future.

Mr. & Mrs. Bailey, Ferndown

Thank you so much for the refurbishment you did on our kitchen/diner, we are over the moon with the result and found you to be helpful, thorough and very efficient.

We would have no hesitations in recommending Building Additions to our family and friends.
