Adding on to a Modular Home

Modulars (as opposed to mobile homes) are usually not that hard to add onto-- in fact, depending on who manufactured your original home, you may be able to get schematics and drawings for adding rooms and wings, from your original manufacturer. The biggest challenges are usually "matching" foundations so you get a good lock of the now onto the old, and then there's the electrical-- you'll probably have to pull some new "home runs" (and possibly an extra breaker panel) from your exterior connection to the power grid, to your addition, routing them AROUND the existing structure, as it seems to be harder to go into the walls on modular homes. At least that's the experience my former in-laws had, when expanding theirs.

I have not had that experience however I drive by one that was built all around and I watched its progress. Today it is attractive and no one would know it was once a modular home. Know of several people that have done it and so it would seem that it would be easy to do.

It really should not be any different than a regular site construction, the homes are built to the same standards, hire professionals to do the work or be sure the persons that are doing the work really have a good understanding of the structure.

My uncle added on to theirs a couple years ago. He added more or less another house. I don't think he ran into that many problems as he basically just used the old entrance to connect it to the other section and went from there. Good luck.

Not something I have done, Modular homes seem like a good idea, and being able to expand it would be ideal. I don't think they are very common in the U.K. yet, although I have read recently that some supermarkets (and Marks & Spencers) are considering providing ready built houses to be placed on your own land (I assume that this is a similar idea to your modular home). Some of these are designed so that extensions can be built on very easily, so perhaps you should check with the original manufacturer to see if they have anything available, and that could give you ideas for what is possible, even if you do build the extension yourself, they may even have plans available (either free or at low cost).
