On date of event; I was working and training on Ground Control with my trainer. There was a NOTAM published and broadcasted on the ATIS that the larger runway; RWY 35L was closed; due to maintenance. All aircraft had to use RWY 35R (unless exceeded weight of 12;500 lbs; where then coordination would take place to use Rwy 35L temporarily). Because of the shorter runway being the ONLY runway in use; as well as being a beautiful; sunny VFR day; traffic levels and complexity were high. For all aircraft to get to the active runway; they must first cross the active runway; but at the departure end; then continue taxi to the active. In the general phraseology used to each aircraft; due to today's closed runway condition; 'hold short of Runway 35R' and runway assignment of 'Runway 35R' were in same statement. An aircraft called for VFR flight to NW with having the current ATIS information. I responded; 'Runway 35R; taxi via Echo; Foxtrot. Hold Short of Runway 35R.' The pilot read back the taxi and hold short instructions correctly. I had many other aircraft on frequency for clearance and taxi requests. I gave a clearance to an aircraft when my trainer and I noticed the aircraft taxi across the active Runway 35R while on Taxiway Echo; then continue on to Foxtrot; as instructed. We immediately made sure that there were no aircraft on final or departing on the active and communicated with the Local controller about what happened. We did not stop the aircraft because his taxi speed was fast and no aircraft were on the active runway at the moment. On his route of taxi he would first need to cross the active runway then be able to proceed onto Taxiway Foxtrot for remaining taxiing to the approach end for departure. Once at the approach end; and before I transferred him to Tower frequency; I notified the pilot of a possible pilot deviation and to contact the tower with the phone number I provided. He later called the tower and spoke the the FLM (Front Line Manager) on duty once landed at his destination. Because of the situation with Runway 35L closed; it may have been confusing to the pilots; instructing them to hold short of their runway assignment. They may have thought that once done taxing via the taxi-way routes; THEN hold short of the active runway at the approach end; where they are to depart from. Most pilots are used to crossing runways with intersections associated with it. Here; at DWH; our airfield configuration is different; and we do not need to say 'Hold short of Runway 35R at ECHO'. After the event; I incorporated that phraseology into my clearances and had no further conflicts; incidents; events; or confusion from the pilots.
Purpose of flight was a personal flight from DWH. On this morning 35L-17R was closed and only 35R was in use.After getting the ATIS info I contacted ground for taxi instructions. Received 'Taxi via Echo and Foxtrot; hold short of 35R'. I read back the instructions correctly. I proceeded to taxi down Echo; checking both directions for aircraft in the air or on the ground; rolled past the end of 35R without stopping; turned on Foxtrot; proceeded to the end of Foxtrot to the 35R hold line; performed the run-up; called ground; and was told to 'call the tower by phone'. I had to think for a minute before I realized what I had done.This airport has an ongoing emphasis program about issues with the taxiways in this area of the airport where several taxiways and two runways are within that small area along taxiway E; which is marked 'Hotspot 2' on the DWH runway diagram. And I was aware of this prior to this situation.First; the order the instructions were issued lead me to picture 'travel via Echo; then Foxtrot; then hold at 35R.'In thinking about this; my mistake was in not completely keeping in mind the bigger picture of operations on this morning. I got too casual when operating in a 'familiar' environment. I should have recognized and expected that hold and; which I did not. It would have helped me if different terminology had been used; i.e. if the controller had said 'hold at 35R Departure' I would have caught myself. From now on I will keep an airport diagram for DWH in the cockpit and LOOK AT IT after receiving taxi instructions to confirm the plan of movement and compliance.
DWH had one runway closed; and the pilot taxied across the departure end of an active runway.
