What we build
Building services across Milton Keynes
GreBcon is a builder in Milton Keynes with more than 12 years of experience. Most of what we do is the building work that changes how a house works: extensions, loft conversions, garage conversions and renovations, along with the structural alterations that make them possible.
Because the same team handles the groundworks, the build and the finishing, we can take a project from an empty plot at the side of the house to a decorated room. Whatever the job, it starts with a site visit and a free quote.
-
House Extensions
Single-storey, side, wraparound and two-storey extensions, built from the footings up and finished inside.
-
Loft Conversions
Dormer, rooflight and hip-to-gable loft conversions that turn empty roof space into a proper room.
-
General Building Work
Structural alterations, steel beams, brickwork, groundworks and roof structures for homes and business premises.
-
Renovations & Garage Conversions
Whole-house and room-by-room renovations, layout changes and garage conversions, finished ready to live in.
-
Kitchen Fitting
New kitchens planned, sourced and fitted, with the plumbing, electrics, tiling and flooring done too.
-
Bathroom Fitting
Bathrooms, en suites, shower rooms and cloakrooms stripped out, re-plumbed, tiled and fitted.
Outside the house
Patios, paths, fencing and landscaping
The same groundwork that goes under an extension goes under a good patio. We also build driveways and retaining walls, put up fences and gates, and finish gardens with turf and planting.

From the site: a two-storey extension in Haversham
The clearest way to see what a builder does is to follow one job from start to finish. These photographs are from a two-storey side and rear extension we built in Haversham, just north of Wolverton, as part of a full house renovation.

Questions
Builder Milton Keynes: your questions answered
Straight answers to the questions we are asked most by people looking for a builder in Milton Keynes. If yours is not here, call or send us a message.
How do I choose a builder in Milton Keynes?
Look at work they have actually done, read their reviews and make sure the quote is in writing and sets out what is included. A good builder visits before pricing, explains the order of work and tells you what needs planning permission or Building Regulations approval. You can see our own projects on this site, from the footings to the finished rooms.
What building work does GreBcon take on?
House extensions, loft conversions, garage conversions, renovations, structural alterations and general building work, along with kitchen and bathroom fitting. Outside, we build patios, paths, driveways and retaining walls, and put up fencing. Most of our work is for homeowners in and around Milton Keynes.
How much does a house extension cost in Milton Keynes?
It depends on the size and type of extension, the ground, the roof and how the inside is finished. A single-storey rear extension and a two-storey side extension are very different jobs. We visit, talk through what you want and give you a written free quote, so you know the cost before you commit.
Do I need planning permission for an extension or loft conversion?
Not always. Many single-storey extensions and loft conversions can be built under permitted development rights, within set limits. Larger extensions, flats, listed buildings and conservation areas need more care. Building Regulations approval is separate and is needed for almost every extension and loft conversion. Milton Keynes City Council is the local planning authority.
How long does a building project take?
A kitchen or bathroom usually takes a week or two. Extensions, loft conversions and full renovations take longer, from several weeks to a few months depending on the size of the job and the weather. We give you a programme with your quote and keep you updated as the work goes on.
Can we stay in the house while the work is done?
Usually, yes. Most of an extension is built outside until the final opening is made into the house. On larger renovations we plan the job in stages, so you keep a working kitchen and bathroom for as long as possible, and we clear up at the end of each day.
Which areas do you cover?
All of Milton Keynes, including Bletchley, Wolverton, Stony Stratford and Newport Pagnell, and the villages around it such as Haversham, Hanslope, Olney and Woburn Sands. We also work just over the border in south Northamptonshire, including Towcester, Old Stratford and Deanshanger.
Do you give free quotes?
Yes. The site visit and the quote are free, and there is no obligation to go ahead. Call 07950 187817 or send the enquiry form to arrange a time.
