“It’s a great setting and an ideal opportunity to get grass-court practice,” said the Scot.
The world number one has added the event to his schedule following his defeat by Thompson, ranked 90th, at the Aegon Championships on Tuesday.
Murray, who is likely to play on Tuesday and Friday, last played at Hurlingham in 2014 after he lost in the last 16 at Queen’s.
He will begin his Wimbledon defence with the opening match on Centre Court on 3 July.
Canada’s Raonic, who lost to Murray in last year’s final at the All England Club, is playing after suffering a first-round loss at Queen’s, while France’s Jo-Wilfried Tsonga and 2010 Wimbledon finalist Tomas Berdych will also appear.
The quality of the guys across the net has a lot to do with it.
I saw a bit of Thanasi Kokkinakis against Raonic, and he played great, some really good stuff when he was behind in the games. Feliciano Lopez is a very good grass-court player and played extremely well against Wawrinka.
And sometimes it’s just coincidence. In an individual sport these results can happen.
‘Three or four hours is enough to prepare’
I found out that I was playing Jordan Thompson a few hours before the match, when I finished practising and saw on my phone that he had replaced Aljaz Bedene, who was injured.
At a Grand Slam, I will usually I talk about the next match with my team the night before, while at other events, when you play day after day, we tend to chat an hour and a half before the match.
That wasn’t the case on Tuesday. I hadn’t gone through any of my pre-match game plan with the team, but online you can get plenty of footage, so they found a little bit of him playing and I had a look on a tablet.
Three or four hours is still enough time to get ready for a different opponent; it can often be a lot shorter.
When it came down to it, he just played better than me.
He served well, I didn’t return the first serve well enough, and my decision-making and movement on the grass can get better.
‘Fewer matches means more practice’
First-round defeats haven’t happened loads during my career at Queen’s Club, but they have happened.
I lost to Nicolas Mahut in 2012 and used the extra time to play a couple of exhibition matches, and then reached my first final at Wimbledon.
Winning a tournament is great and you feel good afterwards, but you can also sometimes think that your game is in a good place and maybe become a little bit more relaxed in that week beforehand.
Now, there is clearly a lot of work required. I need to get myself out there on the practice court.
There will be a slight change of plans and each day becomes extremely important, because I just don’t have the matches behind me. I’ll need to put in a good 10 or 12 days of hard work.
Fewer matches means more practice, so it won’t change my home life too much in the build-up to Wimbledon.
My daughter Sophia sleeps pretty much from 6.30pm most days and I leave to practise pretty early, then I’m not back until quite late.
I’m very thankful she sleeps in the evenings – it’s a good thing – but it does mean I don’t get to see her quite as much.
Hopefully we’ll get the chance to catch a bit of Peppa Pig somewhere along the line.
