The benefits of buying a home with an annexe

Years of rising house prices have driven a growing trend for more than one generation to live in the same household. Often, it’s grown-up children who remain living with their parents until they have saved money for a deposit to buy their own home, and sometimes it can be elderly relatives who have downsized to live with family for care, company – or both.

Either way, buying a property with an annexe – additional self-contained accommodation – can prove a good way for extended families to realise the benefits of living in the same place, whilst also ensuring that everyone can enjoy their own space.

And there may be additional benefits to buying a property with an annexe when it comes to Stamp Duty Land Tax. This is because some properties with an annexe could qualify for Multiple Dwellings Relief.

Multiple Dwellings Relief allows the SDLT on the purchase of two or more dwellings to be calculated using the average value of the properties purchased, multiplied by the number of dwellings, rather than the total purchase price of all the dwellings, and this can lead to a significant reduction in the amount of SDLT charged.

When it comes to defining what constitutes ‘a dwelling’, HMRC guidelines state that a building or part of a building can still count as a dwelling if it is suitable to be used as such. This may be the case even if it is not currently being used or intended to be used in the future as a separate dwelling.

In the case of annexes, the house and annexe will probably be considered as two separate dwellings if each part is completely self-contained and each part has its own front door that is accessible without having to pass through a private living area of the other part to get to it.

However, it is worth noting that some properties with annexes may not qualify for Multiple Dwellings Relief if they are not considered to meet the required guidelines and so it is always important to seek specialist tax advice about a specific property. Once you have sought specialist tax advice, you may also want to instruct an independent valuation on both the main property and the annexe to ensure you are paying the right amount of SDLT.

Professional, efficient surveyors. Get the job done in a timely manner, had our survey back within 5 days of inspection. All team members I spoke with (Tiffany and Billy) were really lovely. Highly recommend. :)


I have only just started working with Stephen and he has already demonstrated the high levels of customer attention and dedication that this company has. The first impression he has caused is such that made me write this review. I have no doubt that the continuous service will be of same level. Looking forward to working further with Stephen. Well done!

Lease extension - I found Daniel Grove very professional and had an excellent understanding of all aspects relating to this transaction. Advice was invaluable, and it was nice to come across someone who did exactly what they said they were going to do. Would not hesitate in recommending the firm and Daniel to anyone who has a lease to extend.

Amazing job and fully professional treatment. The surveyor went above and beyond to check for everything, when he could have easily claim lack of access. In addition he was more than happy to answer questions over the phone and be there to explain the steps.

Within 48 hours I received my detailed report from Joe Arnold which enabled me to see the property as it was and not through rose-tinted glasses! The report highlighted areas where money might need to be spent and provided guidance on questions for my solicitor - just what I needed. Overall, the survey enabled me to re-assess my offer and in this respect was invaluable. Thank you for a friendly and professional service.

100% choose this company. As first time buyers we had a mortgage valuation which said the house was fine. The Arnold & Baldwin survey found over £30,000 of problems. Holes in the roof with daylight visible, damp, woodworm, broken sash windows and poor electrics. This company helped us renegotiate and save a fortune.


Arnold & Baldwin came recommended and I’ve got to say they were brilliant - not just in identifying issues with the property I was looking at but in the way they kept me informed and up to date (ie picking up the phone instead of just posting / emailing communications with you). After dealing with estate agents for so long, it’s nice to have someone who is genuinely on your side.

From my initial interaction with the firm I found them to be prompt, courteous and helpful. I received a detailed Homebuyers report within a week of instructing and was given the opportunity to talk it through with the attending surveyour. Overall excellent service all round, would certainly recommend this firm.
