Belvedere

Belvedere is a town of south east London, England within the London Borough of Bexley. It's situated south east of Thamesmead and is located about 12 miles (19 kilometres) southeast of Charing Cross. Belvedere was in Kent, and in terms of the postal system, remains so. It formed part of the Municipal Borough of Erith ahead of 1965 and improvement work occurred prior to the Second World War, with significant renovation after the Blitz. Despite this, Upper Belvedere and the Village still retains a considerable amount of its Victorian and Edwardian charm and character. Upper Belvedere boasts a church and a number of Victorian and Edwardian brick villas. It boasts numerous standard pubs, restaurants and retail outlets. These consist of The Eardley Arms on Woolwich Road, The Vic on Victoria Street, The Royal Standard in the centre of the village as well as the Fox in Belvedere village. Upper Belvedere also boasts a large sized park and a library that was under threat of getting closed as a result of local government cuts. Thankfully closure threats have been averted as a result on the efforts with the local neighbourhood. A new 'Splash Park', which opened its doors in 2005, was a popular addition to the village, having been created on the site of an old Victorian paddling pool. The splash park retains some of the original paddling pool architecture. Between 1898 and 1961, Callender's Cable Works, at the Erith Works, was patron to Callender's Cableworks Band, an amateur brass band made up of employees of the company. The band was a successful broadcaster on BBC Radio in the 1920s and 1930s. For all of your residence upgrades, be sure that you pick trusted professionals in Belvedere to ensure you get an excellent quality service.

FAQs

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.

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.

Should I use concrete or timber footings?

For 2 metre solid fences it’s recommended to use concrete posts to support each panel. For smaller 1 metre fences or for picket fences with gaps between each timber piece you can use timber posts. A fencing contractor will be able to advise you on the best materials from the length and requirements of a new fence.

how much does a two storey house extension cost?

If you’re considering adding a two storey house extension, then setting a budget for this project would be a great way to get started. Similar to a rear extension, a two storey extension usually leaves the rest of the building needing some work and, due to its size, this may imply the re-development of the entire house - which is why they can be very costly. Some of the other influencing factors that can have big impact on a two storey house extension cost includes: your location, the size of the build, complexity of the design ( anything beyond the standard build will normally require more expertise and time), the glazing to be incorporated ( the more the glass used in the project, the more the material cost), as well as the team used.

Generally, when it comes to extensions, the major part of the expenses will be made on the build of the project. This is because it doesn’t only cover the material cost but also the contractor’s overhead as well as the daily rates. At this stage, the extension prices can be determined by the standard of the work that’s being done.

For a fairly average room size of about 18 square metre, the two storey extension should cost within the range of £2,500 to £3,000 per square metre - with the range being determined by the finishes incorporated. Therefore, a two storey extension of about 18 square metre should cost within the range of £45,000 to £55,000. However, this is with the assumption that there are standard window sizes, bathroom suits are modest, and without any need for any purpose joinery or glazing. If you wish to include all these extra features you’ll also have to pay more to make the total cost between £70,000 to £80,000.
