Multi-Storey House Extension Guide

Today we're going to be looking at multi-storey house extensions and we're hoping you'll find our advice and guidance in our post this week both useful and interesting. Extending your house is always going to be hard work, and you'll need plenty of determination to see it through, but it is ultimately a rewarding experience.

What You Need to Consider

There are certain things you need to be aware of when extending your house because if you don't plan it carefully then you'll find yourself immersed in constant changes and at constant loggerheads with your planning department. There are certain conditions that your extensions must meet in order to pass the planning department's scrutiny.

One Storey, Two or Three

If you're building a single storey extension to the rear or side of the house, then the planning department will normally be more relaxed about this because changes to the house are minimal.

If you're talking two or maybe three storeys then that will be a different story. There'll be far more scrutiny from the planning department, because the changes to the house will be more significant. Issues such as the invasion or compromise of your neighbours privacy or significantly reducing the amount of sunlight caused by shadowing will be considered.

Terraced House Extension

Perhaps you live in a terraced house, if this is the case then an extension to the front of the house is likely to be refused. In fact any storey, back or front is going to have significant impact on your neighbours because you live so close to each other. One possible choice is a ground floor extension that is to the rear of the kitchen with a new bathroom above it. You normally access a bathroom of this type via the rear bedroom.

Semi-Detached House Extension

If you're in a semi-detached house with three bedrooms then you can create a multi storey extension at the side of the house and you could easily fit in a new bathroom or bedroom in here.

Light, Privacy and Windows

You must think about windows and light if you're adding another floor to the house. You wouldn't be allowed to place windows in it at the side if this means you'd be able to look directly into your neighbours garden, or if it looked directly into their living rooms or bedrooms. You can have windows with obscured glass which would be suitable for bathrooms.

Rear extensions can also create problems of their own where light and views through windows could create problems for neighbours. Balconies are a great idea, but again they mustn't look into neighbours gardens or rooms.

Gaining Approval and Planning Ahead

Gaining approval for three storey extensions will prove difficult and you will need to discuss this with your builder and ideally, an architect. You need to make sure any house extension you build, whether it's front or back, does not compromise your neighbours privacy.

House Extension Building Regulations

Building Regulations will depend on the whether your new house extension will have either three or two storeys. Conditions are that they must have adequate sound insulation, one window and an escape route. An extra storey will cause more risk to its occupants, so escape routes and windows hold even more importance, they must also have walls that provide 30 minutes of fire resistance so occupants can escape.
