How to Plan an Extension – 5 Things to Consider

We’re starting with the basics here but, if you don’t get the foundations right…

1. Why Are You Thinking About An Extension?

Maybe you have a home you love, but you’re feeling cramped. An extension is certainly a solution to this problem but think very carefully about what you need more space for. If you’re able to be clear about this – a spare bedroom for guests, room to dine in the kitchen – you’re on your way. If, however, you just need more space everywhere, you may need to accept that moving to a bigger house is the better option.

Alternatively, you may want to extend in order to add value to your home, and an extension can certainly do this. We would recommend, though, that you do your research before making a decision about what kind of extension to build. Not all extensions add substantially to the value of your home. It’s worth talking to local estate agents about what local buyers are looking for and are willing to pay more to get.

2. Will You Use an Architect?

Once you’ve decided on the kind of extension you want, next you’ll need to decide what the design will look like. You may have the skills to do this yourself or perhaps you know an architect who you trust to translate your ideas and draw up the plans. Your third option is to use a design and build company. They will provide a designer to work with you and then, manage the planning through to project completion.

3. How Will Your Neighbours Cope?

This may seem like a sideways leap but getting the neighbours ‘on side’ is integral when considering how to plan an extension. If your plans are modest, you may only need to mention it in passing. If, however, you’re adding a bedroom, or converting your basement, they will face many weeks of disruption.

Talking through your plans openly and honestly with your neighbours could save you exhausting problems once the building starts. And it’s worth remembering that, if you require planning permission, your neighbours will be consulted.

4. Should You Move Out Whilst You Extension is Being Built?

If you stay, you’ll be living in very uncomfortable surroundings for a number of weeks. You may be without a working kitchen, or bathroom for a while, and you’ll have to put up with a lack of water or electricity at times.

Moving out means that you’ll miss all the discomfort, but it’s still a disruption (especially if you have a family) and it could be costly.

5. Do You Need Planning Permission?

Building an extension is likely to involve you in the minutiae of building regulations, permitted development rights and planning permission.

  • Building Regulations. These are the minimum standards for construction of and alterations to a building. Any building work is subject to the approval of an inspector for building regulations.
  • Permitted Developments. These rights permit homeowners to extend their property without having to go through the complex planning process. They tend to apply when the impact on neighbours and the environment is likely to be minimal.
  • Planning Permission. This can only be granted by the local authority and is required when there are plans to build a new structure or change the use of the property. The process is complex and take around 3 months for a decision to be made.
