What are the different types of house extensions?
The term ‘house extension’ simply refers to any structure that’s added to the original building. This can be a loft extension, a basement extension, a kitchen, a living space, or even a new bedroom. Extensions can be made from various materials, from simple brick & block to more expensive, luxury designs, such as those including structural glass.
House extension companies in Hertford should be familiar with period properties. When extending or modifying a period property, it’s important that you know what to look out for. These properties were designed and built decades ago. While they all appear to follow a certain symmetrical pattern, no two properties are the same. All of them have their own quirks. In addition to this, over the decades, they have all been cared for and adapted in different ways.
Undertaking a home renovation or extension is a substantial project, both in a financial commitment and from a time perspective. We thought we would talk you through three of the main things to consider if you are thinking of undertaking a home renovation or using specialist builders to build your house extension in Hertford.

What’s the difference between a first and second fix?
If you’re planning any kind of house extension or loft conversion in Hertford, you’ve probably heard someone using the terms "first fix" and "second fix", but what do they mean?
All home extensions start with a set of awesome architectural floor plans and either a planning application or a lawful development certificate application. But once you’ve actually started construction, you can think of the “first fix” and “second fix” as the two main stages of your building project.
It’s important to know the difference between these two stages, as it’s likely that individual contractors - including plumbers and electricians - will need to come back to finish different jobs during each fix.
Contingency Budget
Generally speaking, it depends on the project. For a ground-floor house extension in Hertford, you are digging into a largely unknown area before the commencement of building works. Occasionally, there may be issues with the property foundations, which could mean additional work is required from your builders. In contrast, a loft conversion usually presents very few unexpected issues. You aren’t uncovering much, so there is very little that remains unknown before the start of the building works.
