Bricklaying- 29 May 2026
Giani and his colleague repaired our wall beautifully for a reasonable price. He talked us through the issues that caused the wall to fail and explained what needed doing. He started the job the next morning arriving promptly and then went about the job with care and pride. I can whole heartedly recommend AGB Construction to anyone looking for builders with good communication, a sincere pride in their work and honest fair pricing.

We’ve had multiple jobs done by Silviya. The first was a small extension and downstairs and partial upstairs refurbishment with new kitchen and 2 bathrooms fitted. This large job was completed within 16 weeks and looks exactly as we hoped. Given the extent of works we moved out for the build. The second was the construction of an outbuilding and garden redesign (patio and astro fitted). Again the results are great. We lived in during this project and I worked from home without disturbance. The latest has been the re-fit of new windows, front door and fixing the front render. Again, the results are very professional and minimal disturbance while the work took place. Will definitely use him and his team again, should we need any more building work and recommend them to others

Extensions- 17 Apr 2019
My extention was left incomplete by a incompetent builder, I had plenty builders coming around for quotes until I decided to go with Peter & Chris after receiving their detailed quote with everything explained in blank and white. I am extremely happy with my choice, as they did a great job finishing the project on time and most importantly great finishes. Peter has an amazing interior design taste, I would definitely recommend picking his brains, Chris on the other hand is very experienced and knowledgeable in building, both work very well together as well as his labourers are very respectful and hardworking. I recommend Peter & Chris to anyone who wants a stress free project. An above and beyond service !

Carpentry- 17 Oct 2025
Nico did a fantastic job. The new wardrobe doors look amazing and fit perfectly after adjusting to fit the older door frames which had settled and moved slightly out of alignment over the years. Better than the original ones. The bedroom doors were replaced and fitted to open to the correct side of the rooms. The broken stair was expertly cut and fitted and matched perfectly to the rest of the stariway. Very solid and completely squeek free. Built to last a very long time. Nico is very reliable, dependable and highly skilled. I highly recommend him for any carpentry work needed.

Architecture- 5 May 2018
Contracted to provide options for a new garage office and storage solution. They turned up promptly and were very polite and professional. Through many discussions they ultimately offered up a very good bespoke solution for our situation and once planning is approved we will have no issue with looking to them to complete the actual build. We have had a lot of issues in the past finding reliable trades but with ArhiTERRA design and build we felt confident in their ability to both visualise and implement the build as well as follow through on their promises. I would say that for anyone considering discussing a project with them that it is worth your time to at least have a meeting with them and judge for yourself.

What to ask a Southall extension builder before hiring?

Before hiring an extension builder in Southall or extension building company in Southall, 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 Southall?

An extension builder in Southall 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 Southall 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 Southall?

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 Southall 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 Southall 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.
