Cobham

Cobham is a village in the Borough of Elmbridge in Surrey, England. It is situated about 17 miles (27 km) south-west of London and 10 miles (16 km) northeast of Guildford around the River Mole. Cobham covers an area of about 3.2 square miles. In line with the 2011 Census, the town features a permanent population of about 9739 individuals. Historically, Cobham comprised two separate communities, Street Cobham and Church Cobham. The former lay on the road to London, and the building now referred to as the Cobham Exchange was formerly a coaching inn. The community of Church Cobham expanded around St. Andrew's Church, which dates back to the 12th century. Although considerably altered and extended during the 1800s, the church preserves a Norman tower and is a Grade I listed building, which is the highest architectural category. The River Mole provides the scene for Cobham's most famous landmark, which is the red brick water mill. It was constructed in the latter part of the 1700s, and it was once a part of a considerably bigger complex. It stands on the site of earlier mills dating back to the Middle Ages. The mill continued to be in use till 1928, when it became uneconomical to continue operating. Since its closure, it has been applied as a storehouse. The town offers a lot of opportunities for sport and leisure activities. Painshill Park is nearby and Silvermere golf course is located in Redhill Road on the north side of the A3. Cobham has four football clubs: Cobham F.C., Mole Valley SCR F.C., Cobham United Football Club and Cobham Town F.C. Cobham also includes a cricket club, Cobham Avorians, formed in 1928. For all of your home upgrades, ensure that you utilise trustworthy specialists in Cobham to ensure you get the most effective quality.

FAQs

Will my extension be expensive?

It depends on the size and type of extension. Small porches or flat roof extensions are very reasonably priced. More substantial two storey extensions can be expensive. In general, the price is roughly proportional to the amount of space you add to your home.

are house extensions worth it?

Often referred to by many as the holy grail of home improvements, house extension comes with a wide range of benefits which makes it easy to see why the extension could be a great uptick in the potential price of your property in terms of sales. So if you’re looking to build a new home extension but still not convinced about the project, we’re here to help you. Being fully aware any home construction work is usually a heavy investment, there’s a huge need to be set on your decision before scheduling the commencement of any work. So are house extensions worth it? Below are some of the top benefits offered by house extensions to help you decide if it’s the most suitable route for you.

• Add To Your Home’s Value

Building an home extension is a great way to add value to your home before selling. Increasing the living space of your home is an incredible appeal to many buyers which significantly increases your property’s total value. However, you must ensure that the extension is impressively designed using top quality materials in order to generate more value.

• Good Alternative To House Moving

The most common reason for moving is usually due to a lack of sufficient space, but with house prices steadily on the increase a cost effective alternative is highly sought after. This alternative is house extension which creates more space for the household to spread out and have more privacy.

• You May Not Require A Planning Permission

You can extend your house and still not need to apply for a planning permission. To achieve this, simply comply with the laid down rules set under the permitted development rights.

• Extra Living Space

If you fill you’re starting to outgrow your existing structure and do not buy into the idea of moving, then your best bet might just be to extend your home.

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.

Can an extension add value to my home?

Yes. Most extensions will add substantial value to your home, and you may find that the extension adds more value than it cost. However, it’s important to be sure that the home remains balanced. Extending your garage and leaving your property with no parking spaces, for example, may impact your ability to sell.
