An outdoor playhouse with slide is definitely one of the best presents that you can get for your kids. This is because you're not simply gifting them a toy or a pretty decoration to look at in the garden: you're giving them a special safe space to play that's only theirs. They'll manage to turn it into a castle, a rocket ship, or wherever their imagination takes them.
Here's what you should think about instead.
Each outdoor playhouse with slide is designed for a specific age range. To ensure your kids' safety, get the right one for them and consider whether you'd rather replace it after a couple of years or invest in a more versatile model that will grow with them for longer.
You also need to consider how many kids will play in it, and this can potentially go beyond the obvious number of siblings, especially if you have an only child: would you like them to be able to welcome more friends inside it? How many?
Keep space in mind, too. Not only do you need to check the dimensions of each playhouse to ensure that it fits in the spot that you have in mind, but you must also allow enough room around it for your kids to play safely, especially at the end of the slide.
As for materials, plastic is the cheapest option and it usually results in brighter colors. It's lighter and easier to move around, but it's not always the most durable.
Wood is a more sophisticated material that can help you achieve a more realistic and balanced look with the rest of your garden. Keep in mind that wooden playhouses will need regular care and must be pre-treated to withstand the elements.
If you're looking for a versatile option that your kids can use occasionally, you can opt for a bounce playhouse with slide instead.
