Welcome to Alpha Constructions

We are one of the leading Essex house extension builders, with over 30 years in the construction industry. We build many home extensions every year throughout Essex and London to exceptionally high standards helping homeowners create extra living space and their dream home.

Not only do we specialize in house extensions in Essex and London but also bungalow extensions. Homeowners often find single-storey buildings too compact and want more space and many of our customers are bungalow conversion owners now.

If you are considering a new extension, whether it is a rear extension, single storey extension, or double storey extension, for that all important additional space, contact us today on  for a free no obligation quotation.

Our friendly team are always available to discuss with you your ideas and offer guidance on an extension.

What Our Client’s Say

A huge thanks to Alpha Constructions team and everyone involved in building our extension. They have created us a large 50 square metre open plan kitchen, dining and lounge area and we look forward to enjoying it as a family for many years to come. The job was started exactly when agreed and the quality of workmanship has been first-rate throughout the build. Communication was excellent and we could always contact someone if we needed to. There were some unforeseen issues with the existing part of the property and the way it was dealt with by Wahid and the team is a true testament to the sheer professionalism of this firm. I would not hesitate to recommend Alpha Constructions and we will definitely be using them for further works.”

Wahid and his Alpha Constructions team built us a loft conversion just in time for Christmas.

All of the tradesmen that worked on our loft conversion were very friendly and helpful. Came up with some great ideas and went above and beyond to make the process as pain-free as possible! Guys tidied up after themselves and were very respectful.

We are absolutely thrilled with our loft conversion, quality of the work and all interactions with Wahid and the guys could not recommend strongly enough.

Alpha Constructions built us a very large extension across the whole length of our home. One of the largest builds the team had done, and we couldn’t be happier. Alpha Constructions was realistic and is the only tradesman I have met who gets back to you each time call. The guys are an established team and clearly work well together, minimising delays as much as possible. We are absolutely thrilled with our extension, quality of the work and all interactions with Wahid and the guys could not recommend strongly enough.”
