Extension builders in Halesowen for domestic extensions, building renovations, and loft conversions. 5-star rated, fully insured, free quotes across B62 and B63.
JCT Building is an extension and renovation builder covering Halesowen and the B62 and B63 postcodes. We deliver domestic extensions, kitchen extensions, rear extensions, loft conversions, and full building renovations across the town, from Cradley to Hasbury, Lapal, and Hayley Green.
Halesowen sits on the western edge of the West Midlands conurbation and has a wide range of housing stock: 1930s semis dominate much of the town, with modern estates in Hayley Green and post-war housing in Hasbury and Lapal. Many homes benefit from rear or side extensions to create modern open-plan living areas. We work with Dudley Metropolitan Borough Council planning requirements and have completed dozens of projects across the area.

JCT Building works across Halesowen and the wider area from our base in Kidderminster. Most of what we do is home extension work: kitchen extensions, side and rear extensions, full house extensions, plus renovations and structural alterations such as removing a load bearing wall to open up a ground floor. It suits homeowners who want more usable space rather than the upheaval of moving house.
Here is what to expect. We come out and look at the property, talk through what you actually need the space to do, and give you a written quote broken down so you can see where the money goes. Once you are happy with the plans and any approvals are in place, we agree a start date and a realistic run of work. The same team is on site throughout, so you always know who you are dealing with. We carry full All Risks insurance along with public and employer's liability cover. You can see finished project photos on our service pages, and our 31 five-star reviews from Google and Facebook give you a fair idea of how we work.
Yes. Halesowen is well within our working area and we are on site regularly across the region. Give us the postcode when you call and we will confirm straight away.
Many single storey rear and side extensions fall under permitted development, but it depends on the size, the plot and the property itself. We will tell you honestly at the first visit whether you are likely to need a full application, and building control sign off is required either way.
Use the contact form on this page or call during opening hours, Monday to Friday 7am to 6pm and Saturday 8am to 1pm. We arrange a visit, measure up and send a written quote so you can compare it properly against anything else you have been given.
