House Extensions at LD Building Services

Right now, LD Building Services offers three types of extensions: garage conversions, single-storey extensions, and double storey extensions.

Garages are important when it comes to property value and living space. Our London extension builders can convert someone’s garage in ingenious ways. What's more, an extension can increase the value of the home by 10%! That's a brilliant way to a higher asking price, for those looking to resell their homes.

Adding just a one-storey extension in the back of the house seems to be the go-to choice of many homeowners in the UK. And getting the garage to be spacious and light is no hard task either — we can add a cheap, full-length sliding door to add more light. Bi-folding doors will also do the trick.

However, having a two-storey extension is by far the best. Our London extension builders can add a whole new wing to a homeowner’s house. A new bedroom, bathroom, kitchen, dining room, lounge — all of that and more with just one extension. Not to mention — an extension is almost an effortless solution, compared to the labour of house hunting.

Loft Conversions at LD Building Services

At LD, we do four types of loft conversions: dormer, mansard, hip to gable and roof lights.

People like installing dormers because they provide more headroom to a loft. Moreover, they can add value to the appeal of the whole house. Of course, if someone wants to install a dormer in the UK, they have to get proper planning permissions. LD Building Services has a lot of experience in loft conversion and dormers are our speciality.

Mansards are usually conversions that we do on period properties. For example, a house in a conservation area has to blend in and look similar to the surrounding houses. More often than not, these houses have mansard roofs.

Of course, some houses have hipped roofs. In other words, these are roofs with three sides. One of those sides is at a lower angle than the rest, which doesn’t leave a lot of headroom in the loft. But these spaces can be converted into gables and provide the homeowner with a lot more room than before.

Finally, there are roof lights or roof windows. The name really says it all—we instal a spacious roof window which gives more light to the loft than it had before.

House Renovation at LD Building Services

That’s right, we’re not just the best London extension builders, we’re also the best house refurbishes and renovators.

Decrepit houses aren’t a good place to live for anyone. But what’s easier, tearing a house down and building a new one or trying to save everything that can be saved? We always recommend the second option. Anyone can save their old home and breathe new life into it. All it takes is precise and resourceful planning.

For example, when we want to renovate a house, we make a few lists. The first list contains everything that HAS to go through a renovation. Stuff that is urgent and can’t be postponed. The second list contains everything that isn’t urgent, but which we should fix. Items on the second list will add to the rent value of the house when refurbished. Once we have the lists, we research the material and its cost. Luckily, there are a lot of business out there that offer inexpensive, yet high-quality materials for home renovations.
