Six things, done properly, in Luton and Dunstable.
We are a building contractor rather than a single trade, so we take the whole job, including the structural work, the other trades and building control sign-off. If your job only needs a bricklayer, we will say so.

House Extensions
Single storey, double storey, wrap-around and garage conversions. Steels, foundations and building control handled, then finished properly inside.

Recent work.
Extensions, lofts, roofs and brickwork photographed on our own sites. Finished rooms first, then the structural work underneath them, because that is the part that decides whether the finish lasts. Where a photograph was taken somewhere other than Luton, the caption says so.

Questions homeowners in Luton ask before they commit.
Straight answers on cost, timescales and how to tell a good builder from a cheap quote.
How much do house extensions cost in the UK?
There is no single figure, and any builder who gives you one over the phone is guessing. The cost of an extension is driven by its footprint, whether it is single or double storey, how much structural steel the opening needs, the ground you are building on and the level of finish you want. What we do is come and look, then put a written itemised quote in front of you for free, so you can see where the money actually goes.
How do I choose a builder?
Check that the person quoting is a member of a professional body with a public register you can search, ask for a written itemised quote rather than a single number, and ask who will actually be on site. Bes Cuni is a Chartered Member of the Chartered Institute of Building (MCIOB) and an Associate of RICS (AssocRICS), and both registers are public. There is a longer answer in our guide to how to choose a builder in Luton.
What is the difference between a builder and a building contractor?
In everyday use they mean the same thing. The distinction people are usually reaching for is between a tradesman who does one trade, such as a bricklayer or a roofer, and a contractor who takes responsibility for the whole job, including the other trades, the programme and building control. BXC Developments does both, and we will tell you which one your job actually needs.
Do you charge for a quote?
No. Quotes and site visits are free, and that is the only price promise on this website. We do not publish fixed prices for building work because no two houses in Luton are the same, and a price list would either be wrong or padded to cover the worst case.
Which areas around Luton do you cover?
Luton and Dunstable are where most of our work is, along with Houghton Regis, Caddington, Slip End, Streatley, Barton-le-Clay, Toddington, Harpenden and Leighton Buzzard. We are also currently working in Hertfordshire, London and Manchester, and each of those has its own page so you can see what we actually do there. If you are somewhere else, ask. We would rather say no honestly than take a job we cannot service properly.
How long will my building work take?
It depends on the job, and the honest answer is that we will not know precisely until we have surveyed it. What we will do is give you a programme with your quote, tell you what could move it, such as building control sign-off, party wall agreements or a material lead time, and then keep you posted week by week rather than leaving you guessing.
What is a Registered Building Inspector, and does it mean you sign off your own work?
Bes is a Registered Building Inspector, Class 2, registered with the Building Safety Regulator. Registration became a legal requirement for building inspectors in England on 6 April 2024 and the register is public, so you can look him up before you ring. What it does not mean is that BXC does your building control. An inspector is not permitted to carry out building control on work his own company has designed or built, and we would not try to. Your building control still comes from the council or from a building control approver you appoint, exactly as it would with any other builder. What it means for you is that the person running your job has been assessed against the Building Regulations from the inspector's side of the table, so the details that normally get picked up at inspection tend to be right the first time.
