Chesham

Chesham is a market town in the Chiltern Hills in the county of Buckinghamshire. It is situated 11 miles south east of the county town of Aylesbury. Chesham is also a civil parish using a town council inside the Chiltern district. Situated inside the Chess Valley, it's surrounded by farmland, as well as being bordered on Amersham and Chesham Bois. The earliest records of Chesham as a settlement which have been found go back to the second half of the 10th century, although archaeological evidence of inhabitants in this location from 8000 BC has been uncovered. The town is most extensively recognised for its 'four Bs'. This consists of boots, beer, brushes and Baptists. The prosperity of Chesham improved considerably over the 18th and 19th centuries as a result of the improvement of the manufacturing industry. Employment in the town currently is supplied mostly by independent companies engaged in light industry, technology and the professional services. With a population of 20343, a number of shops, workshops and cottages can be discovered along the high street to meet consumer demands of the residents.

FAQs

What types of extension are there?

There are many different types of extension. For example, you could install an orangery, flat or pitched roof extension, over-structure extension, single or double storey extension or a glass box extension. Which one of these is most suitable will depend on your existing property.

how long do house extensions take?

If you’re about to start your house extension project and wondering how long it’ll take to complete, you’re not alone! This is one of the most common questions that’s asked by homeowners in the UK and across the globe. However, there’s no single precise answer for this as there are multiple factors that’ll affect the length of time it’ll take to complete your home extension. These factors include the size of the construction work as well as whether you’re planning to live in the house after completion or otherwise.

For a single extension, the length of time it’ll take to complete the home extension is normally up to 3 months. So let’s break this down:

As you would have expected, the first step to be taken is the preparation of the site. You start by digging out the footing and preparing the foundation which should take about 2 weeks. This is then followed by the damp course installation as well as the fitting of any drains needed around the extension which will also take a further 2 weeks.

The 5th week will be for the construction of the external walls as well as putting the blockwork in place for the provision of the cavity wall insulation. A further 2 weeks after this, will be dedicated to the installation of the roof structure and the internal walls.

It’s at this junction that you’ll call on your weather proof installer to fit in your uPVC windows and doors. Once done, the gas fitters and electricians will have to be on site to connect power to your new extension building. Subsequently, this will be followed by internal wall plastering as well as breaking through your main house. Once the plaster is dried, decorations completed and all the required furniture and units installed, the extension is ready for use.
