    How much does a house extension cost in the UK?

    Outside London, the average cost of a house extension project in the UK ranges from £1,200 to £1,500 per metre square.  An additional 50% of the cost of a single-storey extension is required if you want to build a two-storey extension while you need to add around £5,000 to £10,000 if you need to add a kitchen or a bathroom.

    However, these cost estimates may or may not yet include the fixtures, furniture, furnishings, decors, and windows you choose. Make it clear with your contractor so you won’t get surprised when you get your final bill.

    Do I need an architect to extend my house?

    For house extensions, you may or may not hire an architect to get the project done. There is no specific law that tells you to have one. However, it may be very useful and helpful if you have an architect working with you with your house improvement project. Architects will save you from potential violations of local building codes which could cost you a lot.

    Moreover, architects will help you come up with a house extension design that utilises the available space efficiently.  The general rule is – when your project involves a structure that extends outside your main property and therefore affects its exterior aesthetics and function, hiring an architect is smart idea.

    Also, it is highly recommended to hire an architect if your project involves – basement conversion, garage conversion, loft conversion, two-storey extension, wraparound, side extension, and rear extension.

    What size extension can you build in UK without planning permission?

    If your house is detached, you can build an extension of up to 8 metres without a planning permission. If not detached, you can only have it up to 6 metres only. Additionally, the materials you are using must be the same as the existing structure. There must be no raised platforms, balconies, or verandas. Also, it must not be taller than the existing house and must not use up more than half of the outdoor space.

    Does a home extension add value to my property?

    In a lot of cases, the answer to this is in the positive. As dictated by record, a decent and good quality extension can up your property’s value by 23%. For an additional bathroom, such could increase it by 6%, an extended double bedroom by up to 12%, and a house extension by up to 23%.

    How much does it cost to convert a garage into a room in the UK?

    Converting a garage into a room in the UK typically costs around £5,000 to £7,000. The cost could go lower or even higher depending on the size of the garage, the materials, and the contractor you choose.

    How much does it cost to do a loft conversion in the UK?

    In the UK, loft conversion projects may cost you around £1,200 to £2,000 per square metre. However, this estimate most likely excludes finishes. Other factors that could increase or decrease the cost include your specific location, the type of finishing you prefer, how accessible the area is, and the size of the roof alterations required.
