The best house extension builder

House extensions are a fantastic way of increasing space in your home without having to endure the hassle of moving properties. At Firtree Building Services, we have the expertise and staff required to build single and double storey extensions to meet your needs. If you want an extension that has a modern look or something to blend in with your home – our house extension builders’ team can construct it all.

There will always be a pre-site assessment in which we check if your property is suited to an extension build. During this time, we will go over your house extension builder requirements and assess what we can do for you and your home. The team will work hard to find the right materials for your new extension to ensure that it blends in well with your property.

Estate agents often recommend extensions as they add superb value to the home and space is always an attractive prospect for future buyers who want to ensure they get the best value for their money. Hiring Firtree Builders for your house extension builder needs will be a decision that you will not regret.

Moving property can be a pain for homeowners and may not turn out to be worth it in the end. You will have to remember to factor in the moving out costs and increase in stamp duty if you go to a larger property.

    Benefits of our house extension builders

    If you are new to builders of house extension like Firtree Building Services, we recommend that you read our list of advantages that house extensions can give your property:

    More space and lots of it!

    If you need extra room whether it is a bedroom or a new study, a house extension is the perfect way to expand your property without having to buy a new home! It doesn’t matter if you choose a single or double story extension as it offers plenty of space for every home.

    Adds value to your home

    The increase in space can add extra value to your home and will make it more lucrative for would-be buyers who are on the lookout for properties that are great value and have plenty of space. Our team of house extension builders will do their best to make sure that the new extension fits in with your property’s existing appearance.

    Save money on moving out

    Moving out of your home is a costly business as there are so many costs that you will have to add up. Investing in an extension can be more cost-effective than a new home as you only have to fund the extension and not put your hard-earned money into the following:

    • Paying off final bills
    • Survey fees
    • Valuation fees
    • Stamp Duty
    • Land registry fee
    • Local authority searches
    • Mortgage fees
    • Solicitor’s costs
    • VAT
    • Removal expenses

    The only limit is your imagination!

    Whether you work with an architect or designer, we will take their designs and bring it to life with the help of our specialised house extension builder team. If you haven’t created your home from scratch, this is your opportunity to put your own spin on your building. All extensions will be customised to your imagination.

    Less hassle

    Homeowners forget that moving out (especially to a different area) comes with a whole myriad of issues that are not always paperwork-based. Local amenities are very important to a property, and you may find that you miss having a corner shop when you need to go out for a pint of milk. You will have to find a property with the following local amenities:

    • Schools for the children
    • Transport
    • Work
    • Shops
    • Nice neighbours
