Norwich, the county capital of Norfolk, is the base for Envision CAD. This leading Norwich planning company is centrally located in the Union Building on Rose Lane, home of the Rooftop Gardens and Aston Shaw, to name but two.

We’ve carried out work extensively in and around this fine city like this double storey extension in the lovely suburb of Eaton and an office conversion on Thorpe Road. We cover planning for commercial and domestic properties, with our expert and experienced team helping you extend or convert.

But what are the typical stages of planning?

The first step is to assess your budget.

This will dictate the scope of work. A single storey extension will cost much less per square metre than a two storey one and a rough guide is:

Basic quality: £1,000 to £1,680 per square metre

Good quality: £1,680 to £1,920 per square metre

Excellent quality: £1,920 to £2,160 per square metre

A second floor addition will cost you a similar, if not lower, amount.

Next, think about ceiling prices.

If you intend to extend and stay longer term, a ceiling price is not so much of an issue. But if a short or medium term move is likely, you need to seek advice from us as to costs as we have experience of this. For example, if your home in a particular postcode or street in Norwich is worth on average £325,000, would a £50,000 extension automatically hike the valuation to £375,000 as a return on investment? Is the ceiling price there relatively fixed at £325,000 or is there scope for price increases? We can advise.

Now on to the nitty gritty.

Do I need planning permission?

The answer is: not necessarily. There is a PD or Permitted Development ruling and these vary if you’re in a national park or a conservation area, but usually, and we quote, Permitted Development means:

You can extend a detached property by 8m to the rear if it’s a single-storey extension, or by 3m if it’s double

A single-storey extension can’t be higher than 4m on the ridge and the eaves, and ridge heights of any extension can’t be higher than the existing property

Two-storey extensions must not be closer than 7m to the rear boundary

Side extensions can only be single storey with a maximum height of 4m and a width no more than half of the original building

Any new extension must be built in the same or similar material to the existing dwelling

Extensions must not go forward of the building line of the original dwelling

In designated areas (such as areas of outstanding natural beauty, conservation areas, etc), side extensions require planning permission and all rear extensions must be single storey

An extension must not result in more than half the garden being covered

Building regulations apply

Regardless of whether you need planning consent, you need to comply with building regulations. You can find out more here.

Find a reputable and reliable architect and planner

Like being back at school, it pays to do your homework. Ask friends and colleagues for recommendations. Go online and check out company credentials and reviews. Phone or email and see how quickly they respond (and how helpful and professional they are). Check out website portfolios and social media as this can be a good indicator of reputation. If their social media accounts are active, as ours are, it can indicate a real commitment to customer service and excellence – after all no one wants a poor Facebook review or negative comments on LinkedIn.

Finally, when you’ve worked out budget, design, planning consent and sourced a planner, who will know builders, tradesmen and women, it’s time to begin work.

We are an experienced design and build company based in Norwich. You will find our service to be excellent.
