Southwark

The London Borough of Southwark in south London, England forms a part of Inner London and is connected by bridges across the River Thames to the City of London. It was established in 1965 when 3 smaller sized council places amalgamated under the London Government Act 1963. This integrated the former area of the Metropolitan Borough of Southwark, the Metropolitan Borough of Camberwell, as well as the Metropolitan Borough of Bermondsey. It's controlled by Southwark London Borough Council.

The borough covers an overall area of roughly 11.14 square miles. To the south are the London Boroughs of Bromley and Croydon. As outlined by population estimates made during 2014, Southwark includes a permanent population of about 302538 people.

The borough is residence to many cultural, historical and notable attractions. The Shard, Tate Modern, Shakespeare's Globe Theatre, and Borough Market which are the biggest of the venues in Southwark to draw domestic and international tourism. Dulwich houses the Dulwich Picture Gallery plus the Imperial War Museum in Elephant and Castle.

FAQs

How long will a loft conversion take?

It depends on the style and size of the conversion, but in general, a loft conversion will take between 1-2 months. A loft conversion is a substantial building project, and plans will need to be drawn up. This may add to the time it takes to complete your loft conversion.

how disruptive is a loft conversion?

Asides the questions relating to planning permission of a loft conversion as well as the total cost of completing a loft conversion project, this is perhaps the most common question on the loft conversion subject matter. Before making an investment decision, many homeowners will want to know just how disruptive a loft conversion is. Well, we’ve all heard the several horror stories when loft conversion builder with dirty boots tramples all over the fresh and just-acquired shag pile or the noise of the construction loud enough to annoy neighbours from four blocks away or an obvious shortage of teabags, sugar and lots more. Good news is, the disruption of loft conversion is not as bad as people make out. Let’s have a look at how it works!

Just like all other major building projects, a loft conversion is disruptive to your property. However, no two loft conversions are the same, therefore some are certain to be more drastic and invasive than others. In the long run, the project is worth the stress and inconveniences caused and in most cases, it’s usually a very good investment.

Normally, an average loft conversion is expected to last for about 9 to 12 weeks (depending on the complexity of the loft conversion project some might take longer). Some of the factors that affects the duration of a project includes the type of the loft, the design of the loft as well as the style of the property.

Generally, a loft conversion is a lot less disruptive than say completely moving a home. It all has to do with how you’re able to deal with it as a person. And besides, the effect it’s going to have to a large extent depends on the company you hire. A good company will always look to ensure to keep disruptions to a minimal when carrying out the loft conversion project.

an every house have a loft conversion?

If you’re having issues with the amount of space in your home and need an extra space without affecting your garden, loft conversion comes to mind. Not only is it a great solution to creating more living space within a home, but it’s also one of the most budget-friendly solutions you can count on to expand your space by thinking upwards rather than sideways. So if you’re thinking about converting your loft, one thing that almost immediately comes to mind is whether or not your house is suitable for loft conversion.

To answer the question of whether every house can have a loft conversion is a very simple one. Generally, not every house is suitable for loft conversion. This is due to the fact that each and every loft space - from the stairways below and floors to the rafters and the roof up above, is unique. Therefore, the best way to really figure out whether or not a house’s loft offers the potential for conversion is to get in touch with a loft specialist.

So what can make a house not suitable for a loft conversion? Let’s take a closer look!

✓ A house will not be suitable for a loft conversion if the height of the ceiling happens to be too low and it’ll not be possible to have it raised.

✓ If you do not own own the freehold to the loft space, you won’t be able to convert the loft. Surprisingly, this happens to be a common issue in London.

✓ You will not be able to convert your loft if you reside in a conservation area or in a listed building. But you can identify a design solution that’ll still comply with the conservation rules and keep planners happy.

how much value does a loft conversion add?

When its impossible to build out and create more space sideways, why can’t you look upwards? As more and more homeowners in the UK are carrying out their loft conversion project, one question that keeps popping up is the amount of value the loft conversion can add to their homes. However, this is a question that is impossible to provide a single and precise answer to. This is because the value that’ll be generated by a loft conversion is largely dependent on a wide range of influencing factors. To give you a vague idea of the loft conversion value to a property, we’ve put forward a research carried out by industry experts so you can know what you’re in for.

Nationwide carried out a research which shows clearly that a loft conversion including an additional bedroom as part of the building plan will increase a house’s value by up to 21 percent. Since the number of rooms a house has is one of the main metrics for house valuations, loft conversion comes in pretty handy as it’s a great and easy way to convert your house from a 4 bedroom house to a 5 bedroom house prior to sale.

Apart from the financial value aspect, loft conversion also adds more value to your lifestyle which is very unlike nearly other financial investments you can make. More space in your house automatically means more storage or a new room as you wish. A new room can be for a growing family or probably to serve as a guest room. It can also be used as a study space or even an office especially with the rapidly growing rate of people working from home. With loft conversion, the possibilities in terms of value are simply endless!
