Thank you for visiting our website...

Alexander Home Extensions is a well-established Milton Keynes company that has been trading under the same name since 1986. We have completed over 400 projects in the area, mostly home extensions and conservatories, so consider ourselves to be ‘home extension specialists' rather than ‘general builders'.

Over the years, we've seen many building companies come and go, but we've remained strong throughout and will be here for a long time yet, thanks to the high quality of our work, and customers who keep coming back and keep recommending us to friends and family.

You're in safe hands!
•  You'll be pleased to know - we will NOT ask you for an up-front deposit.
•  Fair FIXED prices - our prices are fixed (unless the original specification is altered by
   you, your architect, or the building inspector)
•  All our work is guaranteed, with the further option of Federation of Master Builders
   Master Bond Warranty
•  We utilise FMB's 'F220 Domestic Contract', which you can view here >>

•  Our work method is transparent: we provide full project management and a fail safe    Schedule of Works, so you will know what we are doing, when we are doing it and how    much each stage costs via step-by-step communications.
•  It's your home and it will be treated with the utmost respect at all times - our workforce are    well-mannered and will be as unobtrusive as possible.
•  Our reputation has been built on consistently exceeding customer expectation – we will not    risk ruining our good local name by doing poor work.
