The programme has been presented by Kevin McCloud since it first aired in April 1999, and 124 episodes have been broadcast in eleven series. The twelfth series began on 12 September 2012 on Channel 4.
All episodes generally follow a regular format, with small variations depending on the progress of the build. At the beginning of an episode, McCloud meets the clients embarking on the project; he visits the site with them, and discusses the plans for the building. A computer visualisation or computer-aided design view of the intended project is shown. Once ground work commences, he visits the site periodically, following the build progress, noting any changes, hitches or delays; the build frequently runs over budget and completes later than scheduled. McCloud will often do a piece to camera concentrating on any unique materials or features in the house. He visits again once the building is then made watertight, and the first and second fixes have commenced. He makes a final visit to the site in its finished or near-finished state, once the occupants have moved in. A tour of the house is then given; McCloud brings the episode to a close summarising the house, its construction, and his opinions.
If a house is unlikely to be completed before filming finishes, it will often be revisited in a later episode. In more recent series, McCloud revisits past unfinished builds once they have been completed and may stay overnight.
The properties featured in Grand Designs are hugely varied in style and design, from underground homes to converted water towers to buildings constructed in methods of sustainable architecture; the only common factor is that they are all unusual or extravagant. However the most popular programme of the series for both Kevin McCloud and viewers was Ben Law's home with a sweet chestnut frame made from his own woodland, and costing very little. This was broadcast as episode 3 of series 3. 
Episodes and spin-offs
The first episode of Grand Designs aired on 29 April 1999. Since then over one hundred episodes have been produced and broadcast in twelve series. The Grand Designs brand has also grown in this time with a number of spin-off shows also being made:
- Grand Designs Indoors is a lesser known spin-off, with the same format. As the name suggests the series concentrated on the interior transformation of these properties. Only containing six episodes, this series was broadcast in 2001.
- Grand Designs Abroad focused on properties outside the United Kingdom and was broadcast in 2004.
- Grand Designs Trade Secrets was a spin-off broadcast for two seasons immediately after the main Channel 4 show each week for series seven and eight of Grand Designs respectively. Acting as a companion piece, it gave hints and tips about building and showed some "behind the scenes" material from that week's show.
- Grand Designs Live and Grand Designs Live: Today were one-hour daily programmes broadcast for nine days during the Grand Designs Live 2008 event in London.
- Grand Designs Australia premiered on 21 October 2010 in Australia on The LifeStyle Channel.
- Kevin's Grand Design - A 2 episode special on Kevin McClouds' development of a caravan park into a 44 unit 'FAB' housing estate.
The original Grand Designs series has been released on DVD in the United Kingdom, however the DVD series numbers do not match the television series as some houses are excluded, and the DVDs do not include "revisited" episodes, where there is only a few minutes of new footage. Instead, the new footage from these episodes is included as an extra on the older DVDs.
