Cost-cutting tips for a small extension on the back of the house
Well, you can opt for cost-effective tips when deciding on a rear house extension to get it done in your budget for a high-end extension. We have helped numerous clients get the most out of their budget at GTB Builders, and now, we are discussing how you can save a lot of money when constructing a rear house extension:
-
Save more on fittings
You must know where you can cut extra costs. One quick tip is to invest in wise and budget-friendly fittings. For instance, spending on expensive fittings will not be a worthwhile decision. Instead, you can spend on classic, but cost-effective fittings. Choosing a stylish yet simple model can save you money.
-
Avoid overly complex builds
If you are low on budget, make sure to avoid spending on overly complex builds. For large or long extensions, you may have to spend a hefty amount. Therefore, we suggest that it’s essential to understand your structural costs when we put together their proposed design. When working with your architect, you need to ask your architect to double-check the price with the structural engineer when sorting out your building regulations.
-
Use clever concrete to save more money
Concrete floors are in the trend when it comes to interior design. However, although a concrete floor provides a sturdy and stylish finish, pouring and curing it is both expensive and labour-intensive. That’s why people love concrete tiles. They mimic the look of concrete, and they come at half the price because of their easy assembly. If you want to save more money on a rear house extension, you can also choose concrete tiles. Remember to choose the best quality concrete tiles because there are many who sell low-quality concrete tiles, which don’t last long.
-
Consider skylight
If you are on a tight budget and cannot spend a hefty amount on glass ceilings, you can consider a skylight, which is an alternative to glass ceilings. You also don’t need to compromise on quality, and the level of natural light your rear extension enjoys, if you consider installing skylights in a row.
Large glass features are usually built using structural glass to ensure the longevity of your design. However, it’s an expensive material that usually needs structural support in the surrounding walls. On the other hand, skylights are affordable and save you a lot of money while mimicking the same aesthetic.
Do you need planning permission for an extension at the back of your house?
You need planning permission for a rear extension if it surpasses 3m from the rear wall of a semi-detached house or 4m for a detached house, with limits of up to 6 or 8m under permitted development after prior approval. Two-storey extensions need permission if within 7m of the boundary or taller than 3m at the eaves.
